Lac d'Ambléon

Ambléon

Lac d'Ambléon is a small mountain lake in the commune of Ambléon, in the Ain department, within the Auvergne-Rhône-Alpes region of France. Tucked into the Bas-Bugey massif at the foot of the Tentanet mountain, it sits at roughly 712 metres above sea level and is ringed by conifer forest. Locals and visitors alike rank it among the prettiest lakes in the Bugey area, and it draws a steady mix of walkers, photographers and anglers. What makes this lake distinctive? At barely 5.6 hectares, Lac d'Ambléon is modest in size, and only part of it is genuinely deep — the rest is a marshy fringe of reeds and wetland vegetation that shelters herons, dragonflies and amphibians. One notable trait is that the lake has no visible surface outlet: excess water simply seeps away through the limestone bedrock beneath it, a drainage pattern typical of the karst terrain that underlies much of the Bugey. Because of this ecological richness, the site is listed among the Ain department's Espaces Naturels Sensibles (ENS), one of 32 such protected areas in the department, and it also carries a ZNIEFF type I designation, marking it as a habitat of recognised value for local plant and animal life. Can you swim or fish here? Swimming is not permitted, a rule meant to protect the shoreline habitat and water quality. Fishing, on the other hand, is actively practised — though the lake is privately managed, so a fishing permit is required before casting a line. Permits are sold at the Ambléon town hall and at a sports shop in nearby Artemare. The waters hold trout, perch, pike, whitefish and carp. A set of clear rules governs the activity: no night fishing, no boats of any kind (including for carp baiting), no combustion or electric motors, and no open fires or barbecues along the banks. Anyone under 18 must fish alongside an adult who holds a valid permit. What hiking routes pass by the lake? A roughly 6-kilometre loop trail circles Lac d'Ambléon through the surrounding woods, opening onto viewpoints over both the valley and the water below. It's an easy, well-marked walk suited to families and casual hikers. Those looking for more of a challenge often combine the lakeside loop with the ridge walk to Innimond, which rewards the climb with sweeping views across the Bas-Bugey countryside. Thanks to modest visitor numbers and its largely untouched setting, the area feels quieter than many of the better-known trails in the Ain department. When and how should you visit? The lake lies close to the village of Ambléon, a short distance from Artemare and the main roads linking the Bugey hills to the Rhône valley. Given the forest surroundings and the elevation above 700 metres, late spring through early autumn offers the most comfortable conditions for walking and fishing, while the turning leaves in autumn add another reason to visit for anyone drawn to quiet, forested landscapes. FAQ Is swimming allowed at Lac d'Ambléon? No — swimming is prohibited to protect the lake's plant and animal life. Can you fish at the lake? Yes, but only with a permit, since the lake is privately managed. Permits are available from Ambléon town hall and a sports shop in Artemare. How long is the walking loop around the lake? About 6 kilometres, on an easy, family-friendly trail. Does the lake have protected status? Yes — it is listed as an Espace Naturel Sensible of the Ain department and carries a ZNIEFF type I designation. How big is the lake? It covers about 5.6 hectares, and its deeper zone stays within a range of roughly ten metres.

Gérardmer Lake

Gérardmer

Lake Gérardmer is the largest natural lake in the Vosges mountains, often nicknamed the "Pearl of the Vosges." It sits within the municipality of Gérardmer, in the Grand Est region of France, at an altitude of roughly 660 meters. The lake formed through glacial action, giving it the elongated, spindle-like shape typical of glacial lakes carved into mountain valleys. It covers about 115 hectares, stretches up to 2,200 meters in length and 750 meters in width, and reaches a maximum depth of nearly 38.5 meters. That scale is what sets it apart from the much smaller Lake Longemer nearby, in the neighboring municipality of Xonrupt-Longemer. What does the lake look like up close? A waymarked path circles the entire shoreline, running several kilometers and taking around one and a half to two hours to walk or cycle. The route hugs the water's edge, offering views across to forested hills and to the town of Gérardmer itself, which spreads along the lake's eastern shore. What can visitors do on the water? In summer, the lake becomes the heart of local outdoor life. A supervised beach run by the local sailing club, Union Nautique, operates from June through September, and several unsupervised natural swimming spots are scattered around the shore. On the water itself, visitors can sail, row, paddle a canoe or kayak, or rent a pedal boat. Motorized traffic is tightly restricted — only engineless craft or electric-motor boats are permitted, which keeps the water quiet and clean. Anglers also find good conditions here. Is there anything to do in winter? Above the lake rise the slopes of La Mauselaine ski resort, home to the longest ski run in the entire Vosges range and well-equipped lift infrastructure, including a high-capacity chairlift. That combination makes Gérardmer a year-round destination: a summer lake resort and a winter ski base within a few minutes of each other. Does the lake host any events? Yes — it stages one of the best-known firework displays in the Grand Est region. Large pyrotechnic shows light up the water on 14 July and 15 August each year, drawing crowds from across the area. In winter, additional light and firework shows take place at La Mauselaine during the Christmas and February school holidays. Frequently asked questions How big is Lake Gérardmer? It covers about 115 hectares, with a maximum length of 2,200 meters, a width of up to 750 meters, and a maximum depth of nearly 38.5 meters — making it the largest natural lake in the Vosges. Can you swim in the lake? Yes. The supervised Union Nautique beach operates from June to September, and there are also unsupervised natural swimming areas around the shore. Are motorboats allowed? Only non-motorized craft (sailboats, kayaks, rowing boats) or electric-motor boats are permitted; combustion-engine motorboats are banned. How does it differ from Lake Longemer? Lake Longemer, in the neighboring municipality of Xonrupt-Longemer, is much smaller — about 0.76 square kilometers — and while geographically close, it is a separate body of water. Gérardmer is the larger of the two and the largest natural lake in the whole region. What else is nearby? The La Mauselaine ski resort, with the longest run in the Vosges, and the waymarked shoreline walking path are the main year-round draws for visitors.

Lac de Longemer

Xonrupt-Longemer

Lac de Longemer is a natural glacial lake sitting at the foot of the main Vosges ridge, within the commune of Xonrupt-Longemer in eastern France. Its surface sits at an altitude of 736 metres and covers 0.76 square kilometres, making it one of the two sizeable lakes in this part of the massif. Its modest scale and mountain backdrop make it a favourite half-day trip from Gérardmer and the surrounding valleys. Where exactly is the lake located? The lake lies in the Vosges department, within the Grand Est region, a short drive from the town centre of Gérardmer, with which it shares the Vologne river valley. Wooded slopes and open meadows typical of the mid-altitude Vosges landscape surround the water on most sides. Local roads run along parts of the shoreline, and Gérardmer remains the nearest sizeable tourist town for accommodation and services. Can you swim, and is there a beach? Sections of the shoreline have sandy beach areas suitable for summer swimming. Bathing is allowed but unsupervised, so visitors — particularly families with children — should exercise their own judgement about water conditions. A few designated zones keep swimmers away from boat traffic, giving the lake a calmer feel than some of the busier waters in the region. What else can you do at the lake? Beyond swimming, a pedal-boat rental point operates on the shore, letting visitors get out on the water without their own equipment. Anglers can fish from 1 May to 1 November, with a separate closing date of the third Sunday of September for salmonid species, provided they hold a local fishing permit. Species present include trout, pike-perch, perch, pike, tench, roach and chub. Walkers can follow a marked path that circles the entire lake in roughly an hour, an easy option for those short on time. Is this the same lake as Lac de Gérardmer? No. Lac de Longemer and the neighbouring Lac de Gérardmer are two separate bodies of water, a few kilometres apart and linked through the same Vologne valley. Longemer is noticeably smaller in surface area than the lake at Gérardmer and keeps a quieter, less built-up shoreline — there is no sizeable town directly on its banks, and development along the water stays scattered. Visitors planning a trip to this part of the Vosges should keep the distinction in mind, since the two lakes are often confused given their proximity and shared glacial origin. What is the surrounding area like? The landscape around the lake reflects the wider Vosges: rounded mid-altitude hills, coniferous forest and river valleys. Summers bring a mild mountain climate well suited to both lakeside relaxation and hiking on nearby trails. In winter, the Gérardmer and Xonrupt-Longemer area also serves as a base for reaching Vosges ski resorts, though the lake itself is primarily associated with the summer season. FAQ Is it safe to swim in Lac de Longemer? Swimming is permitted but not supervised — there is no lifeguard, so entering the water is at each visitor's own risk. Do you need a permit to fish? Yes, a local fishing permit is required, and the season runs from 1 May to 1 November, with an earlier closing date for salmonid species. How long does it take to walk around the lake? The path circling the full lake takes about an hour, depending on pace. Is Lac de Longemer the same as Lac de Gérardmer? No, they are two distinct neighbouring lakes; Longemer is smaller and has a quieter, less developed shoreline. Can you rent boats or watercraft? Yes, a pedal-boat rental point is available on the shore.

Lac du Portillon

Oô

Lac du Portillon is a high-altitude lake tucked into the Central Pyrenees, within the commune of Oô in the Haute-Garonne department of southern France, right up against the Spanish border. Sitting at 2,580 meters above sea level and covering roughly 0.34 square kilometers, it ranks among the higher lakes in this part of the range and rewards only those willing to put in a full day of hiking to reach it. Where exactly is the lake located? The lake sits at the head of the Oô valley, well above the better-known lower lakes of Oô and Espingo. Its coordinates, 42.7008, 0.5089, place it deep inside a ring of rocky ridgelines that mark the frontier between France and Spain. The surrounding terrain is stark: bare slopes, glacial moraine, and granite outcrops typical of the high Pyrenean landscape. How do you get to Lac du Portillon? Hikers usually start from the Granges d'Astau car park, reached by road from Bagnères-de-Luchon along the valley leading toward Oô. From there the path first climbs to Lac d'Oô, a lake famous for the waterfall that feeds it from the slopes above. The route then continues along the GR10 long-distance trail and yellow waymarks 42/43 up to Lac d'Espingo, passes Lac de Saoussat, and finally reaches the dam that impounds Lac du Portillon. How long does the hike take? The stretch from the car park up to the area around the Espingo pass typically takes about two hours. Covering the remaining distance to the lake and its refuge adds roughly another two and a half hours. In total, this makes for a demanding full-day outing that calls for solid fitness and sturdy hiking boots, since the final section crosses rocky, uneven ground. Is there anywhere to stay overnight near the lake? Yes. A mountain refuge stands right beside the dam, run by the French alpine club. It offers around 25 beds spread across a handful of small rooms and two larger shared dormitories. The hut serves as a popular base for hikers pushing on toward the higher ridges near the border, and booking ahead is advisable outside the quiet winter months given the limited number of beds. What should visitors know before setting out? The lake occupies a natural basin that was later enlarged with a hydroelectric dam, which explains the noticeably straight, engineered edge of the shoreline near the barrage. The approach crosses protected mountain terrain, so park rules on camping and waste apply along the way. Hikers should carry enough water and windproof layers, since temperatures above the treeline can drop sharply even in midsummer. FAQ How high up is Lac du Portillon? The lake sits at 2,580 meters above sea level, deep in the high-altitude zone of the Central Pyrenees. How large is the lake? Its surface area covers approximately 0.34 square kilometers. Where's the best place to start the hike? Most hikers begin at the Granges d'Astau car park, accessible by road from Bagnères-de-Luchon. Is the trail suitable for beginners? Given its length, several hours of steady climbing, and the altitude involved, the route is better suited to hikers with some mountain experience and good fitness. Can you stay overnight near the lake? Yes, a staffed mountain refuge sits right next to the dam, offering several dozen beds and serving as a stopover for those continuing toward the Spanish border. Is the lake natural? It began as a natural basin that was later expanded with a hydroelectric dam, which is why part of its shoreline looks distinctly man-made.

Lac de Bious-Artigues

Laruns

Lac de Bious-Artigues is a mountain reservoir in the commune of Laruns, in the Pyrénées-Atlantiques department, inside the Pyrenees National Park. Sitting at 1,416 metres above sea level in the Ossau valley, in the historic Béarn region, it covers roughly 0.326 square kilometres. Rather than being an endpoint in itself, the lake works mainly as a launching pad into the higher ground of the range. Where is it and how do you get there? The lake sits in the upper Ossau valley, above Laruns, about 55 kilometres from Pau — roughly an hour to an hour and a half by car depending on traffic. Two car parks serve the site. The first, Bious-Oumettes, takes all types of vehicles and charges a fee during the day, but overnight stays are not allowed. The second, right next to the water, is gated and only open during set hours, and it turns away motorhomes and larger vehicles. On summer weekends the area fills up quickly, so arriving early in the morning is the safer bet. What is there to do at the lake? A footpath circles the entire reservoir, an easy walk that suits families and anyone after a short outing with mountain views rather than a full-day hike. In summer the lake also draws anglers, mainly for trout, and its calm, modest surface is well suited to kayaking or canoeing. Swimming is possible on warmer days too, though the water stays cold even in high summer since it is fed by snowmelt from higher up the massif. Trails nearby — the gateway to the Ayous lakes Bious-Artigues is the usual starting point for the hike to the Ayous lakes, one of the best-known loop routes in this part of the Pyrenees. The trail links several small lakes, including Lac Gentau and Lac Bersau, with views along the way of the distinctive Pic du Midi d'Ossau, whose silhouette famously reflects in Gentau's still water on a clear day. The full loop runs about 16 kilometres with several hundred metres of ascent, so it is best treated as a route for reasonably fit walkers rather than a casual stroll. A mountain hut, the Refuge d'Ayous, sits along the way and offers a stopping point for a rest or a meal partway through, and part of the route overlaps with the GR10, the long-distance trail that crosses the entire Pyrenees from east to west. Walkers looking for something shorter can also aim just for Lac Gentau and turn back from there. Frequently asked questions Can you swim in Lac de Bious-Artigues? Yes, swimming is possible in summer, though the water stays cold because the lake is fed by run-off from higher parts of the Pyrenees. How long does it take to drive there from Pau? About an hour to an hour and a half by car, depending on traffic and the season. Can you park right next to the lake? Yes, but the car park closest to the water has limited opening hours and does not accept motorhomes — the other option, Bious-Oumettes, is more flexible. How long is the hike to the Ayous lakes? The full loop typically takes five to six hours; the walk to Lac Gentau alone can be much shorter if that single viewpoint is the goal. Is the area suitable for children? The path around Bious-Artigues itself is easy and family-friendly, but the full loop to the Ayous lakes calls for reasonable fitness and proper footwear.

Lac de la Landie

Égliseneuve-d'Entraigues

Lac de la Landie is a small highland lake in the commune of Égliseneuve-d'Entraigues, in the Puy-de-Dôme department, Auvergne-Rhône-Alpes region. It lies within the Auvergne Volcanoes Regional Nature Park, on the Artense plateau, at an elevation of roughly 1,035 metres. Clermont-Ferrand is about 70 kilometres away, and the lake sits between two well-known massifs: the Sancy chain to the north and the Cantal massif to the south. Where exactly is the lake? The lake occupies a remote corner of the Artense plateau, a landscape shaped by both ancient volcanic activity and glaciation, deep in the French Massif Central. Far from major roads, the surrounding countryside has kept a quiet, sparsely built character, dominated by pastures, peat bogs and deciduous woodland. How did the lake form? The basin is volcanic in origin, but its present outline owes more to later glacial action. Unlike the neighboring volcanic lakes of the region, which tend to be round and regular in shape, Lac de la Landie has an elongated, irregular contour — the result of a glacier stretching the original hollow. The lakebed is formed of basalt, a reminder of Auvergne's volcanic past. What are its physical characteristics? The lake covers an area of roughly thirty hectares, with a maximum depth of about twenty metres. It is fed by a small watercourse, the May stream, along with several tributaries and deep springs rising from the ground. Where the stream enters the lake, a peat bog has formed — a habitat typical of highland lakes on the Artense plateau. Can you fish here? Lac de la Landie is a privately owned lake, reserved exclusively for fly fishing. Its stock is unusually varied, including several species and strains of salmonid fish: trout (including the aguabonita variety), brown trout, multiple strains of rainbow trout, brook char, and ouananiche, a landlocked strain of Atlantic salmon. This diversity and the quality of the fishing have earned the lake a reputation among fly fishing enthusiasts that extends well beyond France. Because it is private, the opening and closing dates of the fishing season are set by the owner, independent of the general angling calendar that applies to public waters. What can visitors do without a rod? Access to the lakeshore is free and open to the public — visitors can walk around the lake, take in the views toward the Sancy and Cantal massifs, and observe the peat bogs and deciduous forest that surround it. Because the fishery itself is private, angling on the lake is reserved for guests of the site's operator rather than the general public. FAQ Where is Lac de la Landie located? In the commune of Égliseneuve-d'Entraigues, Puy-de-Dôme department, on the Artense plateau within the Auvergne Volcanoes Regional Nature Park. How high up is the lake? At an elevation of roughly 1,035 metres. Is the lake natural? Yes. It has a volcanic origin, and its current elongated shape was later reworked by glacial action. Can anyone fish there without permission? No — the lake is private and fishing is reserved for fly fishing arranged through the site's owner. What else is there to see nearby? Views of the Sancy chain and the Cantal massif, along with the peat bogs and deciduous forests characteristic of the Artense plateau landscape.

Lac de Fabrèges

Laruns

Lac de Fabrèges is a mountain lake in the French Pyrenees, in the commune of Laruns in the Pyrénées-Atlantiques department, at the heart of the Ossau valley. It sits at an altitude of 1241 metres and covers an area of roughly 0.54 square kilometres. The lake marks a well-known stop on the road climbing up the valley, right next to the cable car station that carries visitors further up the mountainside toward the Artouste ski area. Where exactly is the lake? Lac de Fabrèges lies in the upper Ossau valley, on the road heading toward the Col du Pourtalet, the mountain pass on the border with Spain. Its coordinates are approximately 42.875°N, -0.397°W. Steep, forested slopes and high alpine meadows surround the water, with the distinctive silhouette of the Pic du Midi d'Ossau, one of the emblematic peaks of the French Pyrenees, visible in the background. What draws visitors here? The main draw of the area is the cable car (télécabine) that departs from the lakeshore. In a matter of minutes it lifts passengers to roughly 2000 metres, at the La Sagette station, opening up wide views over the Ossau valley and the surrounding summits. From that upper station runs the famous Petit Train d'Artouste, a narrow-gauge tourist railway ranked among the highest-altitude rail lines in France. The train follows the mountainside for around an hour before reaching the vicinity of Lac d'Artouste, a separate and much higher lake that visitors then reach on foot after a short walk from the final station. Lac de Fabrèges itself is also a pleasant stop for a short stroll along the shore, whether before or after riding the cable car. In summer, the valley draws hikers heading up toward the high passes and ridgelines; in winter, its position next to the Artouste ski area keeps the whole area busy with winter sports. How to get there? The Ossau valley is easily reached via the main road running from Pau through Laruns toward the Spanish border. Following this route past Laruns, drivers reach a car park by the lower cable car station, right at the edge of the lake. This is the natural starting point for anyone planning to ride the cable car or simply take a short walk around the area. Frequently asked questions Can you swim in Lac de Fabrèges? The lake mainly serves as a scenic starting point for the valley's attractions rather than as a swimming spot. How long does the cable car ride from the lake take? The télécabine to the upper La Sagette station takes only a few minutes, climbing several hundred metres in altitude. Can you walk from Lac de Fabrèges to Lac d'Artouste? No — Lac d'Artouste is a separate, much higher lake, reached by taking the cable car and then the Petit Train d'Artouste, followed by a short walk. When is the best time to visit? Summer offers green valley scenery and hiking trails, while winter turns the area into the base for the Artouste ski resort. Is parking available near the lake? Yes, a car park at the lower cable car station beside the lake serves visitors during the tourist season.

Lac de Rabuons

Saint-Étienne-de-Tinée

Lac de Rabuons is a high-altitude lake in the municipality of Saint-Étienne-de-Tinée, deep inside the Mercantour National Park in the Alpes-Maritimes department. Sitting at roughly 2,500 meters, it's the largest lake in the whole department, framed by the bare, rocky terrain typical of the Haute Tinée valley, with the approach trail delivering wide views over the surrounding peaks. How do you get there? The hike starts in Saint-Étienne-de-Tinée and climbs more than 1,500 meters over a round trip of roughly 21 kilometers. Most hikers set aside 7.5 to 8 hours of walking, treating it as a full day out — or splitting it with an overnight stay at the lake. After about three hours of climbing, the trail reaches the well-known Chemin de l'Énergie, a flat stretch running for a couple of kilometers past a disused power station, originally cut into the rock by EDF workers. From there it's roughly one more hour of climbing to reach the lakeside refuge. What makes this lake different? Lac de Rabuons isn't fully natural in its current form. Between 1938 and 1939, the original lake was enlarged by carving a water intake into the rock, intended to feed a hydroelectric plant. That power station was never actually built, but the intake itself was installed and is still in use today — EDF draws on it to supply hydroelectric production in the Tinée valley, with a major refurbishment carried out in 2013 and 2014. This is also the story behind the Chemin de l'Énergie: a trail with two tunnels and a scenic balcony section, originally used by the workers who built the intake. What will you find once you're there? On the lakeshore stands the Refuge de Rabuons, where you can stop for a midday meal (typically served between noon and 2 p.m.) or book a night with dinner and breakfast included — a practical option if you'd rather spread the effort over two days or catch the lake at sunrise and sunset. The surrounding landscape is stark and mineral, with bare slopes and rock outcrops replacing vegetation, characteristic of Mercantour's high-altitude zone. When is the best time to go? June through September is the best window, once the trail is clear of snow and the full route can be walked safely in a day. Earlier in the season, the upper sections can still hold snow, making the climb longer and more demanding. FAQ How high up is Lac de Rabuons? The lake sits at around 2,500 meters, inside the Mercantour National Park. How long does it take to reach the lake? The full round trip from Saint-Étienne-de-Tinée is about 21 kilometers and 7.5 to 8 hours of walking, with around 1,500 meters of elevation gain. Can you stay overnight at the lake? Yes — the Refuge de Rabuons offers meals as well as overnight stays with dinner and breakfast. Is Lac de Rabuons a natural or artificial lake? It began as a natural lake and was enlarged between 1938 and 1939 with a water intake for hydroelectric use, which EDF still operates today.

Lac au Duc

Ploërmel

Lac au Duc is a man-made lake in the commune of Ploërmel, in the heart of Brittany's Morbihan department. Covering roughly 250 hectares, it ranks among the largest bodies of water in the region and has long served as the area's main outdoor playground, drawing visitors for sailing, swimming, and lakeside walks. Where exactly is the lake? Lac au Duc sits on the boundary between Ploërmel and the neighbouring commune of Taupont, just a few kilometres from Ploërmel's town centre and within easy reach of the Brocéliande forest, famed for its Arthurian legends. Its coordinates are approximately 47.9515°N, -2.4112°E. A short drive from central Ploërmel gets you to the shore, and cycling and walking paths link the lake to the town. What is there to do around Lac au Duc? A water sports centre on the shore rents equipment and runs lessons for beginners and experienced practitioners alike: dinghy sailing, catamarans, windsurfing, kayaking, and stand-up paddleboarding are all on offer. Those after a faster pace can try water skiing or wakeboarding, while pedal boats and electric boats suit a calmer outing. On land, the site includes archery, disc golf, an orienteering course, and open-air pitches for beach volleyball and air badminton. Cycling and mountain-biking trails run along the shoreline, with bikes available to hire on site. Between the water and land activities, the lake appeals equally to families and to visitors planning a full day of outdoor activity. Is there a beach for swimming? Yes. The lake has a sandy beach split into two supervised swimming zones — a deeper section for confident swimmers and a shallower one better suited to children and less experienced swimmers. Picnic spots, play areas, and shaded rest zones surround the beach, making it an easy destination for a day trip without much planning. Where can visitors stay nearby? On the Taupont side of the lake, a campsite makes the most of its position on Brittany's largest artificial lake. It offers pitches for tents and caravans set among oaks and pines, along with mobile homes, chalets, and unusual accommodation options such as barrel-shaped cabins and hiker's huts. It works well as a base for exploring both the lake and the nearby Brocéliande forest, or for day trips into Ploërmel itself. When is the best time to visit? The lake is busiest from spring through early autumn, when the water sports centre and the supervised beach are both open. In summer, Lac au Duc becomes one of the most popular leisure spots around Ploërmel, so booking equipment or a campsite pitch ahead of time is worth doing. Outside the peak summer months, the lake still appeals to walkers and cyclists looking for a quieter pace. FAQ How big is Lac au Duc? The lake covers about 250 hectares, making it one of the largest bodies of water in Brittany. Can you swim in the lake? Yes, the beach has two supervised zones, one deeper and one shallower, catering to different swimming abilities. What water sports are available? Sailing, windsurfing, kayaking, paddleboarding, pedal boats, water skiing, and wakeboarding, with equipment and lessons for all levels. Is there accommodation close to the lake? Yes, a campsite sits right on the shore in Taupont, offering tent pitches, mobile homes, and unusual cabin-style lodging. How do you get to the lake from Ploërmel? It's a few kilometres from central Ploërmel, reachable by a short drive or via cycling paths that follow the shoreline.

Lac de Trémelin

Iffendic

Lac de Trémelin is a lake in the commune of Iffendic, in the Ille-et-Vilaine department of Brittany, roughly half an hour's drive west of Rennes, right at the edge of the Brocéliande forest. The lake sits within a wider domain of more than 220 hectares of woodland, moorland and open water, and the site draws over 400,000 visitors a year, making it one of the busiest outdoor destinations in this part of Brittany. What is there to do at the lake? The shoreline is organised around Aventur'O Lac, a leisure base run by the Montfort Communauté. It brings together: canoe, kayak and pedal-boat hire, a tree-top adventure course with zip lines, an equestrian centre, beach volleyball, a playground and mini-golf, walking and cycling paths that circle the whole lake. Walking around the domain and enjoying the woodland is free; visitors only pay for the specific activities they choose. Can you swim in the lake? Yes. The beach holds the Pavillon Bleu (Blue Flag) label, awarded for water quality and environmental management. Supervised swimming runs through the summer season, generally from late June to the end of August, mostly in the afternoon. Water temperature reaches around 20°C in summer, and a diving platform by the jetty is available for more adventurous swimmers. Is fishing allowed? The lake is also popular with anglers. A local fishing association (AAPPMA) manages fish stocks and fishing rights on site. What else is worth seeing? L'Aparté, a small contemporary art space, sits within the domain, and a campsite (Camping du Lac de Trémelin) operates right next to the lake for visitors staying longer. During July and August, early-morning guided canoe outings are organised at sunrise - a quieter way to experience the lake before the daytime crowds arrive. A lakeside restaurant and snack bar overlook the water, and picnic spots are scattered around the shore for families bringing their own food. Who is it suited for? The mix of a supervised beach, water sports, a tree-top course and family-friendly paths makes Lac de Trémelin an easy day trip from Rennes, and equally a good base for a longer stay in the Brocéliande area, known for its Arthurian legends. FAQ How far is Lac de Trémelin from Rennes? About a 30-minute drive west of Rennes, in the commune of Iffendic. Is entry to the lake free? Walking around the domain is free; specific activities such as equipment hire, the tree-top course or horse riding are paid separately. When can you swim? Supervised swimming operates during the summer season, generally from late June to the end of August, in the afternoon. Is the lake suitable for children? Yes - the supervised beach, playground, mini-golf and gentle walking paths make it a family-friendly spot. Can you stay overnight nearby? Yes, a campsite operates directly on the lakeshore.

Gour de Tazenat

Charbonnières-les-Vieilles

Gour de Tazenat is a near-perfectly circular volcanic lake in the commune of Charbonnières-les-Vieilles, in the Puy-de-Dôme department of the Auvergne region in France. It sits close to the village of Manzat and marks the northern edge of the Chaîne des Puys volcanic range. How did this lake form? Gour de Tazenat is a maar, a crater created by a phreatomagmatic eruption — a violent reaction that occurs when rising magma meets groundwater. This eruption took place roughly 29,000 years ago. The blast left behind an almost perfectly round depression measuring about 700 meters across, now filled with water to a depth of around 66 meters. Such geometric regularity is unusual among volcanic lakes, and it is precisely this feature that draws attention from visitors viewing the lake from nearby high ground or aerial photographs. Where exactly is Gour de Tazenat located? The lake sits at coordinates 45.98°N, 2.991°E, in the northwestern part of Puy-de-Dôme. This corner of Auvergne belongs to the Chaîne des Puys, a chain of volcanic cones and domes running through central France. Gour de Tazenat lies right at the northern tip of this chain, making it somewhat set apart from the more famous puys further south while still clearly sharing their volcanic origin. What can visitors do at the lake? A footpath circles the entire lake, covering roughly 7 kilometers. It is an easygoing route that lets walkers take in the lake from every angle and appreciate the scale of its circular shape. Two unsupervised swimming spots are also available along the shore: one near a local crêperie, reached by a wooden staircase leading down to the water, and another accessible via a quieter path along the bank. The water is clear, but there are no lifeguards on duty, so swimmers use the lake at their own risk. Does Gour de Tazenat have any cultural significance? The lake has a place in French literature — writer Guy de Maupassant referred to it in one of his short stories, a sign that this spot has long caught the attention of both local residents and visiting observers of the countryside. Today it remains a reference point for anyone learning about the volcanic history of Auvergne, offering tangible evidence of how intense volcanic activity shaped this part of France during the Pleistocene. Why visit Gour de Tazenat? The site combines educational and recreational value. On one hand, it is a clear, easy-to-grasp example of a maar landscape — no geology background needed, since the regularity of the shape speaks for itself. On the other hand, it is a quiet spot for a walk, a swim, or simply time by the water, away from the heavier tourist traffic found at the better-known sites of the Chaîne des Puys. It suits travelers looking for a less obvious but equally genuine encounter with volcanic Auvergne. FAQ What is Gour de Tazenat? It is a volcanic maar lake located in the commune of Charbonnières-les-Vieilles, in the Puy-de-Dôme department, at the northern end of the Chaîne des Puys. How was the lake formed? It formed through a phreatomagmatic eruption about 29,000 years ago, when groundwater met magma and produced a circular crater. How large and how deep is the lake? It is nearly perfectly circular, roughly 700 meters in diameter, with a depth of about 66 meters. Can you swim in the lake? Yes, there are two unsupervised swimming areas — one near a crêperie with wooden stairs, and another reached by a path along the shore. Is there a walking trail around the lake? Yes, a footpath of about 7 kilometers circles the entire lake. Where exactly is Gour de Tazenat? Near the village of Manzat, in the commune of Charbonnières-les-Vieilles, at coordinates 45.98°N, 2.991°E.

Plan d'Eau de Cournon-d'Auvergne

Cournon-d'Auvergne

Plan d'Eau de Cournon-d'Auvergne is a man-made recreational lake on the south-eastern edge of Cournon-d'Auvergne, right on the banks of the Allier river, just a few kilometres from Clermont-Ferrand in the Puy-de-Dôme department (Auvergne-Rhône-Alpes region). The whole landscaped site covers roughly 18 hectares of green space and water, making it one of the larger leisure complexes near the Auvergne regional capital. What can you do on the water? The designated swimming area covers about 5,000 m² and is typically watched over by lifeguards during the summer season (broadly July and August). For visitors who want more than a spot on the sand, wakeboarding is on offer, along with a canoe and kayak rental point for paddling out onto the calm water. A fishing pier along the bank caters to anglers. And if you're not here for the water? The grounds around the lake work as a family-oriented sports and leisure complex in their own right. There are tennis courts, a mini-golf course, an outdoor fitness area, sports pitches, a skate park and children's playgrounds. Pétanque players will also find a dedicated pitch. Those who prefer to stay on foot can follow several marked walking trails looping around the lake and along the Allier, while more puzzle-minded visitors can try orienteering courses, with maps available from the town hall. A small animal park on site is a popular stop for families with children. Accessibility and facilities The beach and the fishing pier have both been adapted for visitors with reduced mobility. A free car park with roughly 200 spaces sits at the entrance, making the site easy to reach by car. An on-site restaurant covers meals, and a three-star campsite, Le Pré des Laveuses, stands right next to the complex — useful if you're planning to stay more than a day. Good to know before you go Water quality can vary from one season to the next, and swimming is sometimes suspended temporarily because of cyanobacteria (blue-green algae) blooms, with notices posted on site and on the town's website. When that happens, the splash pools and water play areas for children usually remain open, so it's worth checking current conditions before planning a swim. FAQ Can you always swim at Plan d'Eau de Cournon-d'Auvergne? Not always — the swimming zone is occasionally closed for sanitary reasons, such as cyanobacteria blooms, so it's best to check current conditions before your visit. How big is the site around the lake? The whole area covers roughly 18 hectares along the Allier river, with a designated swimming zone of about 5,000 m². Is there somewhere to eat or stay overnight? Yes, there's an on-site restaurant, and a three-star campsite, Le Pré des Laveuses, sits right next to the complex. Is the site accessible for visitors with reduced mobility? The beach and the fishing pier have both been adapted for reduced-mobility access. How do you get there and where can you park? The site sits on the south-eastern edge of Cournon-d'Auvergne, close to Clermont-Ferrand. A free car park with about 200 spaces is available on site. What can you do besides swimming? Tennis, mini-golf, wakeboarding, canoe and kayak rental, fishing, pétanque, a skate park, walking trails, orienteering courses and a small animal park.

Lac du Cinto

Lozzi

Lac du Cinto is a high-altitude glacial lake sitting on the south-western flank of Monte Cinto, Corsica's highest peak at 2,706 metres. It lies within the commune of Lozzi, in the Haute-Corse department, at an elevation of roughly 2,289 metres. The setting is stark and rocky — scree slopes and bare granite give the basin an almost lunar look — and the lake sits under the shadow of the Capu Falu summit, inside the Regional Natural Park of Corsica (Parc naturel régional de Corse). Where exactly is the lake? Lac du Cinto lies deep in the mountainous interior of Haute-Corse, within the ridge system surrounding Monte Cinto, the island's highest massif. Its coordinates are approximately 42.3708 N, 8.9339 E. The nearest trailhead village is Lozzi, a small mountain settlement on the southern side of the massif. How do you get to Lac du Cinto? The standard approach starts in the village of Lozzi and follows the southern side of Monte Cinto. The trail passes a mountain refuge partway up the slope, then continues on steep, rocky paths toward the lake — roughly two hours from the refuge, with the full round trip from Lozzi taking about 7 to 8 hours. The path is uneven and demanding, so it suits hikers with some mountain experience, reasonable fitness, and proper footwear. A second route, from Haut-Asco on the northern side, climbs all the way to the summit of Monte Cinto itself; it is longer, more technical, and involves greater elevation gain, but does not pass directly by the lake. When is the best time to visit? The hiking season around Monte Cinto runs from June to October. Outside this window, the high trails are often snow-covered or icy, and weather at this altitude can shift quickly. Hikers should carry enough water, sturdy gear, and a map or GPS device, since the terrain above the tree line is open and only loosely marked in places. What is there to see along the way? The route crosses a cross-section of Corsican mountain landscape: dense maquis scrub at lower elevations, pine forest higher up, and finally a bare alpine zone above the tree line. The lake itself is small, ringed by loose rock, and set against the backdrop of Capu Falu and the wider Monte Cinto massif. For hikers pushing on to the summit, it serves as a natural rest point; for others, it is a worthwhile destination in its own right — a chance to see a high-altitude glacial lake without tackling the summit push. FAQ How high up is Lac du Cinto? The lake sits at roughly 2,289 metres, on the south-western slope of Monte Cinto. How long does it take to reach the lake? From Lozzi via the mountain refuge, the round trip typically takes 7 to 8 hours; from the refuge itself, it's about a 2-hour walk to the lake. Is the trail difficult? Yes — it's steep and uneven, crossing genuine high-mountain terrain, so it's best suited to hikers with some experience and good fitness. When should I plan a visit? Between June and October, when the trail is generally free of snow and ice and weather conditions are more stable. Can I continue from the lake to the summit of Monte Cinto? Yes, the route from Lozzi connects to the summit approach (2,706 m), though reaching the top requires an additional, more demanding stretch beyond the lake.

Lac des Confins

La Clusaz

Lac des Confins is a small mountain lake sitting at the foot of the Aravis range, a short distance from the centre of La Clusaz in the Auvergne-Rhône-Alpes region of the French Alps. Open pastureland and patches of spruce forest surround the water, with Pointe Percée, the highest summit of the Aravis massif, rising in the background. The combination of gentle scenery and easy access makes it a popular stop for families and for walkers looking for a short outing without serious elevation gain. Where exactly is the lake? Lac des Confins sits at an altitude of just over 1,300 metres, roughly 5 km from the centre of La Clusaz, a village better known as a ski resort. Its approximate coordinates are 45.9158°N, 6.4761°E. The setting is a broad pastoral plateau typical of this part of the Bornes-Aravis area, with the steep flanks of the Aravis range visible in every direction. How do you get there, and do you need to walk? An access road runs from La Clusaz to the lake and is open to cars year-round, with free parking close by. In summer it is equally possible to reach the lake on foot or by mountain bike, following waymarked trails that start in the village itself. That makes the site accessible both to visitors after an easy stroll and to more experienced hikers who want to combine a visit to the lake with a longer route toward Pointe Percée. What is there to do around the lake? A signposted footpath circles the water, and the full loop takes about 45 minutes to walk — an easy outing suitable for most fitness levels. Along the way, walkers pass a small chapel that serves as a distinctive landmark. Marmots are often spotted on the surrounding slopes, and trout live in the lake itself. For visitors after something more active, two zip-lines have been rigged over the water, roughly 700 and 300 metres long. In summer the lake also serves as a starting point for easy walks along the GR de Pays waymarked trail, while in winter it becomes a destination for snowshoeing routes setting out from La Clusaz. Where can you eat and take a break? Several mountain inns with terraces sit around the lake, serving traditional Savoyard dishes such as tartiflette and baked cheese on a crust of bread. These make a natural stop halfway through a walk or a longer bike ride, particularly in summer, when the terraces fill with visitors enjoying the view over the surrounding peaks. Frequently asked questions Can you drive to Lac des Confins? Yes, the access road is open year-round and there is free parking close to the lake. How long does it take to walk around the lake? The full loop around the lake takes about 45 minutes and is an easy walk suitable for most visitors. What can you do at the lake in summer? Besides the lakeside walk, visitors can try two zip-lines over the water, watch for marmots and trout, or continue on longer hiking routes toward Pointe Percée. Is the lake accessible in winter? Yes, in winter the area is a destination for snowshoeing routes from La Clusaz, though reaching it takes longer and requires proper winter gear. How far is the lake from La Clusaz? The lake lies about 5 km from the centre of La Clusaz, a well-known ski resort in Haute-Savoie.

Lac Lérié

La Grave

Lac Lérié is a small mountain lake set on the Plateau d'Emparis, in the municipality of La Grave in the Hautes-Alpes department, right in the heart of the Oisans massif. Sitting at roughly 2375 metres above sea level on the right-hand side of the Romanche valley, it's one of the most visited lakes in this corner of the French Alps. Where exactly is the lake? Lac Lérié sits close to a second, slightly smaller lake, Lac Noir, and to a cluster of small pools known as the Lacs Cristallins, together forming a well-loved hiking objective on the Emparis plateau. The plateau itself unfolds at around 2000 metres, west of the village of La Grave, and works as a natural balcony above the Romanche valley below. What can you see from the lakeshore? The main draw of Lac Lérié is the view: straight across to the north face of la Meije and the neighbouring Râteau (3809 m), two of the most recognisable summits in the Oisans massif. On a clear day you can also make out the Girose glacier, reachable from La Grave by cable car. The lake's calm, shallow water often mirrors the surrounding peaks, which is why it's such a popular stop for photographs along the trail. How do you get to Lac Lérié? Several trails lead up to the Emparis plateau and its lakes, most commonly starting from the village of Le Chazelet or from the Rif Tort trailhead west of La Grave. Part of the route follows a section of the GR54, the long-distance path that loops around the entire Ecrins massif. For most visitors, Lac Lérié makes a moderate day hike, though a longer two-day loop linking it with Lac Noir, with an overnight bivouac in between, is just as popular. What should you know before setting out? The Plateau d'Emparis falls within the Natura 2000 network, which brings a few specific rules: bivouacking is only tolerated for a single night, between 7pm and 9am, dogs must stay on a lead, and campfires are banned outright. The best window for a visit runs from June to October — earlier in the season, the higher parts of the plateau can still be under snow. In summer the meadows around the lake fill with blue gentians and alpine edelweiss, and marmots are a common sight among the surrounding rocks. Why is it worth the walk? Lac Lérié brings together everything hikers look for in the Alps: a relatively easy approach, wide open plateau scenery, and a front-row view of one of the most striking massifs in the French Alps. It also makes a solid base for anyone planning a longer stay around La Grave, a village best known for its glacier ski area and for the climbing reputation of la Meije itself. Frequently asked questions How high up is Lac Lérié? The lake sits at around 2375 metres above sea level, on the Plateau d'Emparis. Which mountains can you see from the lake? From the shore of Lac Lérié you get a view of the north face of la Meije and the Râteau (3809 m), and on clear days the Girose glacier as well. What's the best starting point for the hike? Most hikers set off from Le Chazelet or the Rif Tort trailhead, both west of La Grave. When is the best time to visit? June through October, once the trails across the high plateau are clear of snow.

Lac des Plagnes

Abondance

Lac des Plagnes is a mountain lake in the commune of Abondance, in the Haute-Savoie department of the Auvergne-Rhône-Alpes region. Sitting at roughly 1,191 metres of altitude in the Chablais massif, it is the largest lake in the entire Abondance valley, and it pairs easy car access with genuinely alpine scenery — a combination that draws both casual walkers and anglers through the summer months. Where is Lac des Plagnes and how do you get there? The lake sits about 5 km from the centre of Abondance village, best known for its historic abbey. A paved road leads all the way to the shore, where a car park lets visitors reach the water without a long approach on foot — though motorhomes are not allowed to stay overnight in the car park. From there it only takes a few minutes to walk down to the shoreline and start the loop around the lake. What can you do at the lake? The main draw is the walk around the lake itself: a short, easy loop suitable for most visitors, though not recommended for pushchairs or wheelchairs. Benches and picnic tables are set up along the way, making it easy to stop for a break by the water. Swimming and any form of water sport are forbidden, with one exception — fishing is permitted. In winter, the surrounding area is used as a cross-country skiing route. Why is the lake part of a UNESCO Geopark? Lac des Plagnes is one of the designated sites of the Chablais UNESCO Global Geopark. Interpretive panels along the walking path explain how this stretch of the Alps has evolved over the last 20,000 years, from retreating glaciers to the peat bogs and glacial lakes seen today. Nearby, the Cubourré site is specifically dedicated to this geological history. When is the best time to visit? The lake looks its most striking in late May and early June, right after the snow at higher altitude has melted. At that point the water takes on a turquoise colour, set against the still snow-capped peaks behind it, creating a strong contrast of colours. Later in summer the water level drops somewhat, but the walking loop stays open and accessible for the whole season. What views does the lake offer? From the shores of Lac des Plagnes, hikers get a clear view of the sunlit side of Mont de Grange, the highest point of the Abondance valley at 2,432 metres. It serves as a natural landmark for orienting yourself in the surrounding terrain. How can you extend the walk? Visitors looking for a longer outing can head toward the nearby Lac de Tavaneuse, another lake in this part of the Chablais massif that is often combined with Lac des Plagnes into a single loop. Another option leads to the Cubourré waterfall, with its small cascades. More determined walkers can continue toward the Refuge des Tindérêts, roughly an hour and fifteen minutes away on foot. Right at the lake, the restaurant Chez Rémy offers a place to eat after the walk. FAQ Can you swim in Lac des Plagnes? No. Swimming and water sports are banned; fishing is the only permitted water activity. Is the lake easy to reach? Yes, a road leads directly to a car park by the shore, so no long approach on foot is needed. How long does the walk around the lake take? It is a short, easy loop suitable for most visitors, though not ideal for pushchairs or wheelchairs. Is there an entrance fee? No, access to the lake and the walking trail is free. What is the best season to visit? Late May to early June, once the snowmelt gives the water its turquoise colour while the peaks above are still snow-capped.

Lac de Vonnes

Châtel

Lac de Vonnes is a small lake in the commune of Châtel, in the Haute-Savoie department, within the Auvergne-Rhône-Alpes region of France. It sits in the Chablais massif, inside the well-known Franco-Swiss Portes du Soleil area, just outside the centre of the village of Châtel. The lake works as both a recreation spot and a quiet viewpoint set among alpine slopes and forest. Where exactly is the lake located? Lac de Vonnes lies at an altitude of around 1,250 metres, just off the road leading out of Châtel toward the higher parts of the valley. The lake covers roughly 2 hectares and reaches a depth of about 10 metres. It isn't a fully natural lake — it was formed as a water body on what used to be marshy ground, which explains its regular outline and managed shoreline. A footpath runs all the way around the water, letting visitors circle the whole lake on foot in a matter of minutes. What can you do at Lac de Vonnes? In summer, the lake serves as a local recreation area for both Châtel residents and visitors to Portes du Soleil. Pedal boats and stand-up paddle boards can be rented right at the water's edge, and there's a children's playground and a picnic area nearby. One of the lake's defining features is a fountain jet that shoots water up to around 40 metres — visible from a distance and especially striking in the evening when it's lit up. Fishing at the lake Lac de Vonnes is also a well-known fishing spot. It's stocked with rainbow trout, brown trout (fario), char and minnow, with fish ranging from roughly 20 to 80 centimetres. The fishing season generally runs from early May to late September, with access limited to morning hours. Anglers bring their own tackle, barbless techniques are required, and equipment can also be rented on site. Trout and tench under 25 centimetres must be released back into the water. How do you get there, and is it accessible? The lake has its own car park, including spaces reserved for visitors with disabilities. The site is wheelchair accessible, both for self-propelled chairs and with assistance. Local shuttle buses serve the area in both winter and summer — on different routes depending on the season — making it easy to reach without a car from central Châtel. Dogs are welcome but must be kept on a leash. Why is it worth a visit? Lac de Vonnes isn't built for crowds; it's a calm spot woven into everyday life in Châtel, one of the main villages of Portes du Soleil, an area primarily known for its extensive ski and mountain-biking network. In summer, the lake offers a natural resting point after hikes through the surrounding Chablais trails, and its still water framed by mountains draws both families with children and anglers looking for quiet. FAQ Can you swim in Lac de Vonnes? The lake is mainly set up for recreation — pedal boats, paddle boarding and walking around the shore — so it's worth checking on-site rules before swimming. Is fishing available year-round? No, the season effectively runs from spring to early autumn, and fishing is limited to set morning hours. Can you reach the lake without a car? Yes, local shuttle buses run from Châtel during the season, and there's also a car park right at the lake. Is the lake suitable for children? Yes, there's a playground and a picnic area by the water, and the path circling the lake makes for an easy family walk.

Lac de l'Aiguillette

Les Houches

Lac de l'Aiguillette is a mountain lake in the commune of Les Houches, in the Haute-Savoie department of France, sitting at the southern tip of the Aiguilles Rouges range, right across the valley from the Mont Blanc massif. The lake occupies a high plateau known as Carlaveyron and counts as the largest body of water inside the nature reserve that surrounds it. The setting is classic glacial terrain — rocky ridgelines, alpine pastures, and shallow pools scattered across a wide basin, all mirroring the peaks above. Where exactly is the lake? Lac de l'Aiguillette (roughly 45.925 N, 6.8111 E) sits on a plateau carved by glaciers that retreated tens of thousands of years ago, leaving behind a broad, bowl-shaped amphitheater. The basin lies beneath the summit of Aiguillette des Houches (2,285 m), which delivers sweeping views over the Mont Blanc massif on one side and the Fiz range on the other. The lake itself is visible from the summit trail, tucked among smaller pools locally called "gouilles" that dot the plateau. The Carlaveyron nature reserve The lake lies within the Carlaveyron National Nature Reserve (RNN103), established on 5 March 1991 and covering close to 599 hectares. The reserve is a genuine biodiversity hotspot: surveys have recorded 132 plant species and 460 animal species, including 224 species of insects. The landscape reads like a natural water garden — streams, peat bogs, marshy hollows, and small lakes woven between outcrops and grazing meadows. What lives around the lake The reserve's peat bogs host rare plants, among them carnivorous sundew and alpine orchids, while the wetlands support a dragonfly species typical of high-altitude bog habitats. In summer, chamois and Alpine ibex come down to the shores of Lac de l'Aiguillette to drink and to graze on bilberry shrubs nearby. Elsewhere in the reserve, patient observers may also spot lynx, golden eagle, three-toed woodpecker, black grouse, and roe deer, though these are far less commonly seen than the ibex and chamois at the water's edge. How to reach it The usual starting points are the Parc de Merlet in Les Houches or the hamlet of La Flatière, at roughly 1,370 m. From there, trails climb past the Bel Lachat refuge (2,152 m) and the Chailloux mountain pastures toward the Carlaveyron plateau, passing in sight of the Bossons Glacier, one of the largest icefalls in Europe. One popular loop that links the lake with the Aiguillette des Houches summit runs about 17.7 km with over 1,300 m of elevation gain — a full day out for fit, experienced hikers. The final push to the summit itself follows an exposed rocky ridge that calls for scrambling with hands; reaching the lake on the plateau below is a considerably gentler proposition. FAQ Can you swim in Lac de l'Aiguillette? The lake sits inside a strictly protected nature reserve, so swimming and other disturbances to the ecosystem are discouraged. The point of a visit is to observe the landscape and wildlife, not to use the water for recreation. How long does it take to reach the lake? It depends on the route and starting point. The approach from Parc de Merlet or La Flatière typically takes several hours one way, and the full loop over the Aiguillette des Houches summit is a whole-day undertaking. Is the hike suitable for beginners? Getting up to the Carlaveyron plateau is demanding in terms of fitness but technically moderate. Pushing on to the Aiguillette des Houches summit is another matter — the ridge sections are exposed and require a good head for heights. When is the best time to visit? Summer is the best window, once snow has cleared from the higher stretches of trail and the peat bogs are passable. It's also the season when chamois and ibex are most often seen coming down to drink at the lake.

Étang d'Eychelle

Bethmale

Étang d'Eychelle is a small mountain lake in the French Pyrenees, set within the commune of Bethmale in the Ariège department, in the Couserans area. Sitting at roughly 1,894 metres above sea level, the lake covers less than a hectare — a quiet, secluded pool ringed by grassy slopes and rocky ridges, characteristic of the high-altitude zone of the French Pyrenees. Where exactly is the lake? Eychelle lies on the eastern flank of the ridge overlooking the Bethmale valley, close to two distinctive peaks: Tuc de la Seube (2,096 m) and Tuc d'Eychelle (2,315 m), which lends its name both to the lake and to the nearby shepherd's hut, the Cabane d'Eychelle, standing at about 1,900 m just above the water. The whole area falls within the Parc Naturel Régional des Pyrénées Ariégeoises (Ariège Pyrenees Regional Nature Park). How do you get there? The most common starting point is the Col de la Core (1,395 m), reached by a local departmental road. From there, the trail climbs toward the Col d'Auèdole (1,727 m), from which the lake is a short distance further on — the ascent from the pass typically takes about ninety minutes. Part of the route follows a variant of the GR10, the well-known long-distance Pyrenean trail (the GR10D branch). A second option is a longer approach from the Étang de Bethmale (1,074 m), sitting further down the same valley. This variant lengthens the walk but lets hikers combine both lakes in a single outing. The hike is generally rated moderate, with total elevation gain running into several hundred metres depending on the chosen approach. What is there to see? The scenery around Eychelle is classic high-Couserans terrain: a modest sheet of water framed by alpine grassland and bare rock, with no tourist infrastructure beyond the shepherd's shelter. The lake holds brown trout (truite fario), making it a target for anglers, though swimming is prohibited here, as it is at the neighbouring Étang de Bethmale. Given the altitude and terrain, the best window for a visit runs from spring through early autumn; in winter, snow cover can make the trail difficult or impassable without proper equipment. Who is this hike for? This is a destination for hikers looking for a quiet, low-key goal away from the busier Pyrenean trails. The absence of crowds, the untouched surroundings, and the views toward Tuc de la Seube and Tuc d'Eychelle are the main draws. Sturdy hiking boots, water, and a good trail map are worth bringing, since waymarking on the higher stretches can be sparse. Frequently asked questions How high up is Étang d'Eychelle? The lake sits at an altitude of around 1,894 metres. Where's the best place to start the hike? The Col de la Core (1,395 m) is the most convenient trailhead; from there, via the Col d'Auèdole (1,727 m), the lake is roughly ninety minutes away. Can you swim in the lake? No, swimming is prohibited, just as it is at the nearby Étang de Bethmale. Are there fish in the lake? Yes, Eychelle holds brown trout (truite fario). When is the best time to hike here? Spring through early autumn is best; in winter, snow can make the trail hard to access.

Lac de Montriond

Montriond

Lac de Montriond is a mountain lake in the commune of Montriond, in the Haute-Savoie department of France, set within the Chablais massif at an elevation of 1,072 metres. Locals sometimes call it the "green lake" because of the striking emerald colour of its water. It ranks as the third-largest lake in the whole department and is one of the busiest summer stops in the Portes du Soleil area, right next to Morzine. Where is the lake and how do you get there? The lake sits within Montriond commune, only about a 10-minute drive from central Morzine. During the summer season, a free shuttle bus also runs from the centre of Montriond down to the lake, which is a handy way to avoid parking pressure at peak times. A free car park is available right at the lakeside. Its approximate coordinates are 46.2083°N, 6.7278°E. How big is the lake, and where does the water come from? Lac de Montriond covers roughly 32 to 33 hectares, with a maximum length of 1,320 metres and a maximum width of 253 metres. It belongs to the drainage basin of the Dranse river, specifically the branch known as the Dranse de Montriond. Steep, forested slopes covered in conifers rise around the shoreline, and combined with the vivid colour of the water, this gives the lake one of the most recognisable landscapes in the Chablais massif. What is there to do at the lake in summer? During the summer months, particularly July and August, a supervised swimming area with a beach operates on the western shore. At that time of year the lake works as a full outdoor leisure spot: visitors can paddle a canoe or kayak, try stand-up paddleboarding, take a pony ride, or play a round of mini-golf. There is a playground for children, and activities such as bubble football or laser biathlon can also be found near the water. This mix draws both families with young children and visitors simply looking for a scenic, relaxed afternoon by the water with mountain views on every side. What is the Cascade d'Ardent, and is it worth the walk? The best-known destination for a walk around the lake is the Cascade d'Ardent, a waterfall roughly 30 metres high that flows into the lake from the south. A footbridge crosses the waterfall itself, letting visitors get close to the falling water. The out-and-back walk to the falls is one of the most commonly recommended short hikes near Morzine, and it is manageable for most fitness levels. Who is this destination best suited for? Thanks to its gentle surroundings, supervised beach, and short distance from Morzine, Lac de Montriond works well as a day-trip destination for families with children, couples after a scenic short walk, and summer visitors to the Portes du Soleil area — a region better known for its winter ski slopes than for its lakes. Frequently asked questions How high up is Lac de Montriond? The water surface sits at an elevation of 1,072 metres. How large is the lake? It covers around 32 to 33 hectares, with a maximum length of 1,320 metres and a maximum width of 253 metres, making it the third-largest lake in the Haute-Savoie department. Can you swim in the lake? Yes. A supervised swimming area with a beach operates on the western shore in summer, mainly during July and August. How do you get to the lake from Morzine? It is about a 10-minute drive; in summer, a free shuttle bus also connects central Montriond to the lake. What is the main sight nearby? The Cascade d'Ardent, a roughly 30-metre waterfall flowing into the lake, crossed by a footbridge that offers a close-up view of the falls.

Lac de Peyre

Le Reposoir

Lac de Peyre is a small mountain lake sitting at roughly 2,100 metres above sea level in the Bornes-Aravis massif, within the commune of Le Reposoir in Haute-Savoie. It's one of the best-known hiking destinations in this part of the French Alps: a modest but strikingly situated body of water, ringed by rocky summits and reached by a steady stream of walkers every summer. Where exactly is Lac de Peyre? The lake sits high in the massif, tucked below Pointe Blanche and flanked by Pointe de Balafrasse, Pointe du Midi and Pointe de Dzérat. The usual starting point is the Col de la Colombière, a mountain pass reachable by car only from roughly June to October or November — outside that window, snow closes the road. The commune of Le Reposoir itself is best known for its former Carthusian monastery, the Chartreuse du Reposoir, but the lake lies well above the monastery valley, higher in the mountains. What does the hike look like? From the Col de la Colombière, the walk to the lake covers around 3 km one way and typically takes about an hour and a half of climbing, depending on the exact route chosen. The path crosses open, sun-exposed slopes, rocky and uneven in places, with no shade anywhere along the way — carrying enough water is essential in summer. The payoff is the sight of the lake resting in a rocky hollow, framed by a wide mountain panorama. What can you see from around the lake? The viewpoint near Lac de Peyre delivers one of the more rewarding panoramas in the region: the Mont Blanc range on one side, the Aravis and Bornes massifs on the other, and on a clear day the surface of Lake Geneva (Lac Léman) in the distance. That view, alongside the lake itself, is what draws hundreds of hikers a day during peak season. What about wildlife and protection status? The area around Lac de Peyre falls within the European Natura 2000 network of protected sites. Marmots and ibex are regularly spotted on the surrounding slopes and rocks, and encountering them is a common highlight hikers mention afterward. Vegetation here is sparse and distinctly alpine, shaped by a short growing season and intense sun exposure at this altitude. When is the best time to go? The hiking season lines up closely with the period the Col de la Colombière road stays open — roughly June through mid-November, depending on snow conditions. In peak summer the trail can get busy, so an early start is worth planning for anyone hoping for a quieter walk. Some hikers choose to camp overnight near the lake instead, to catch the surrounding peaks at sunrise and sunset. FAQ How do you get to Lac de Peyre? Drive up to the Col de la Colombière in the commune of Le Reposoir, where the footpath to the lake begins. The pass road is closed outside the summer-to-autumn season. How long does the hike take? The climb from the pass usually takes about an hour and a half, covering roughly 3 km one way. Is the trail difficult? No climbing skills are needed, but the path crosses rocky, sun-exposed slopes with no shade, so good fitness and enough water are important. What will you see along the way? Besides the lake itself: views of the Mont Blanc, Aravis and Bornes massifs, Lake Geneva on clear days, and wildlife such as marmots and ibex. Is the lake accessible year-round? No — the access road and the trail are effectively unreachable in winter, when snow closes the Col de la Colombière.

Lac de la Persevérance

Chamonix-Mont-Blanc

Lac de la Persévérance is a high-altitude alpine lake sitting at roughly 2,460 m, inside the Aiguilles Rouges Nature Reserve, in the municipality of Chamonix-Mont-Blanc, Haute-Savoie, France. It lies above the far more popular Lac Blanc, which keeps it quieter and makes it a target mainly for seasoned hikers after solitude and a close-up view of the Mont Blanc range. Where exactly is the lake? The lake occupies a rocky, mineral basin at the foot of the Aiguilles Rouges massif, above Lac Blanc (2,352 m) and the Lacs des Chéserys (2,210 m). It marks the highest point on the popular loop that strings the three lakes together. Its water runs noticeably darker than Lac Blanc's, and far fewer walkers make it this far. How do you get there? The usual starting point is the Col des Montets (about 1,461 m), on the road linking Chamonix and Argentière, near Tré-le-Champ. From there the path first climbs to Lac Blanc, then branches off toward the upper lake along a rockier, steeper stretch that crosses scree and a few exposed sections. Depending on the exact loop chosen, the round trip covers roughly 12.6 to 13.7 km with 1,200-1,500 m of cumulative elevation gain. The ascent alone typically takes 3 to 4 hours, and the full there-and-back outing runs 6 to 8 hours. What should you know before setting out? The route is rated difficult. Several rock steps are fitted with ladders and metal rungs, and some stretches call for sure footing and no fear of exposure. Snow patches can linger on the upper sections well into early summer. The best window to hike is June through September, once the trail has cleared. Sturdy boots, trekking poles, and enough water are essential — there is little to no water source along the way. What views does it offer? The lake sits in a stark, rocky alpine setting ringed by the Aiguilles Rouges. The approach opens onto views back over the Chamonix valley and across toward the Mont Blanc massif. It suits hikers who have already done Lac Blanc and want a rawer, less crowded corner of the same reserve. Frequently asked questions Is this hike suitable for beginners? No. It is rated difficult, with rocky, exposed sections and fitted ladders, and it calls for good fitness and steady footing. How long does it take to reach the lake? The climb from Col des Montets usually takes 3 to 4 hours, depending on fitness and the exact route taken. When is the best time to go? Between June and September, once snow has cleared from the higher sections. Is the lake close to Lac Blanc? Yes — Lac de la Persévérance sits higher and farther along the same popular loop through the Aiguilles Rouges Nature Reserve, past Lac Blanc. Where does the trail start? Most commonly at Col des Montets, on the Chamonix–Argentière road near Tré-le-Champ.

Lac de Saint-Pardoux

Saint-Pardoux-le-Lac

Lac de Saint-Pardoux is a man-made lake in the Haute-Vienne department, in the historic Limousin region of central France, roughly 25 km north of Limoges. Formed by damming the Couze and Ritord rivers, it now covers around 330 hectares, making it the second-largest body of water in Haute-Vienne after Lac de Vassivière. The lake sits at an altitude of about 360 metres and its shoreline is shared by three communes: Compreignac, Saint-Pardoux-le-Lac and Razès. How did an artificial lake end up here? Planning for the dam began in 1968, and the valley was flooded in 1976. The lake officially opened to visitors the following year, in 1977. In the decades since, it has grown into one of the region's main leisure destinations, second only to Vassivière in scale and popularity among Limousin's inland lakes. Is the whole lake open for every kind of water sport? Not quite — the surface is split into zones so that different activities don't get in each other's way. About 192 hectares are set aside for quieter pursuits such as sailing and pedal boats, 88 hectares are reserved for motorised watercraft, and the remaining 50 hectares are dedicated to fishing. This zoning keeps sailors, anglers and motorboat users out of each other's paths. What can visitors actually do here? The activity hub is the Chabannes water sports base, jointly run by the Ligue de l'Enseignement and the local PALL sailing club. From here you can rent canoes, stand-up paddleboards, pedal boats, sailing dinghies, catamarans and funboats, with options suited to complete beginners as well as more confident sailors. The base also runs supervised group sessions — archery, blowpipe shooting, orienteering — and, during school holidays, multi-sport camps for young people that mix water- and land-based activities. Land-based visitors aren't an afterthought either: there are mountain biking trails, plus rental points for electric scooters and electric skateboards. A standout addition is the wake park at Fréaudour, opened in 2019, which uses a cable lift to tow water-skiers and wakeboarders — no motorboat required, which opens the sport up to a much wider range of visitors. Where can you swim, and when? Swimming is officially permitted, and lifeguard-supervised, only in July and August. The lake's three main beaches — Santrop, Fréaudour and Chabannes — each come equipped with picnic tables, a children's play area, showers, toilets and small kiosks selling drinks and ice cream. For visitors who'd rather skip open water, one of the sites also has a swimming pool, in operation since 2017. Who is this lake best suited to? Lac de Saint-Pardoux works well for families and active travellers alike. Its combination of open water, surrounding woodland and the gentle Limousin countryside means a visit can be as simple as a day on the beach or as packed as a weekend of sailing, paddling and cycling. FAQ How far is the lake from Limoges? About 25 km to the north, making it an easy day trip from the city. Can you swim in the lake year-round? No — supervised swimming is limited to July and August, though sailing, canoeing and other water sports run for a longer season. How many beaches does the lake have? Three supervised beaches: Santrop, Fréaudour and Chabannes, each with full visitor facilities. Is the lake natural? No, it's an artificial reservoir created by damming the Couze and Ritord rivers; the valley was flooded in 1976 and the lake opened to the public in 1977. What water sports is the lake known for? Sailing, canoeing, paddleboarding and pedal boats, plus cable-tow wakeboarding and water-skiing at the Fréaudour wake park, running since 2019.

Lac Fourchu

Livet-et-Gavet

Lac Fourchu is a mountain lake sitting at roughly 2,048 metres above sea level on the Taillefer plateau, within the commune of Livet-et-Gavet in the Isère department, Auvergne-Rhône-Alpes region. It lies less than an hour's drive south of Grenoble, deep in the Belledonne-Taillefer range, and forms part of a cluster of high-altitude lakes scattered across the plateau — the best known neighbour being Lac de Poursollet. Where does the lake's name come from? The French word "fourchu" means forked or fork-shaped. The name describes the lake's outline, which splits into two distinct arms resembling the letter Y or a pitchfork — a shape best appreciated from the slopes surrounding it. This forked silhouette is what sets Lac Fourchu apart from the rounder lakes nearby on the same plateau. What is the surrounding landscape like? Lac Fourchu sits on a broad plateau covered in alpine grassland, dotted with peat bogs and wetlands that hold meltwater for much of the year. This section of the Taillefer massif falls under Natura 2000 protection, recognised for its heathland, peatland and rocky habitats. The scenery is stark and high-mountain in character — open pastures, rocky ridgelines, and the Taillefer summit rising above the plateau. How do you get to Lac Fourchu? The most common starting point is the car park near the Poursollet chalets, at around 1,650 metres. From there, the trail to the lake takes roughly one to one and a half hours, gaining about 400 metres of elevation — a route generally considered manageable for most hikers, including families, though it still calls for the fitness needed for high-altitude walking. A longer and tougher alternative starts from the village of Les Clots, regarded as one of the more demanding approaches to the Taillefer lakes plateau, following steeper, rockier ground. What should you know before heading out? Because of the altitude and exposed terrain, weather on the plateau can shift quickly, so checking the forecast and packing wind and rain protection is worthwhile even in summer. Most of the trail runs above the tree line, offering clear views but little shelter if a storm rolls in. The area carries nature-protection status, so hikers are expected to stay on marked paths to avoid disturbing the peatland vegetation and nesting birds. FAQ Where exactly is Lac Fourchu located? On the Taillefer plateau, within the commune of Livet-et-Gavet (Isère), Auvergne-Rhône-Alpes region, at an altitude of around 2,048 metres. Where does the lake's name come from? From the French word "fourchu" (forked), describing its Y-shaped, forked outline. What is the most popular route to the lake? Starting from the Poursollet car park (around 1,650 m), from which the lake is roughly a one to one-and-a-half-hour walk. Is this hike suitable for beginners? The Poursollet approach is relatively gentle and manageable for most reasonably fit walkers; the route via Les Clots is significantly harder. Is there another lake nearby? Yes — Lac de Poursollet sits on the same plateau and is a common starting point or waypoint on the way to Lac Fourchu. Is the area protected? Yes, it falls within the Natura 2000 network due to the peatlands and heathland habitats of the Taillefer massif, so visitors should keep to marked trails.
