Lacs de Prals
Saint-Martin-Vésubie
Lacs de Prals is a cluster of glacial mountain lakes above Saint-Martin-Vésubie, tucked into the high Mercantour National Park in the Alpes-Maritimes. Sitting at the head of the Upper Vésubie valley, the lakes occupy a rocky glacial basin ringed by bare ridgelines and alpine pasture, and rank among the best-known day hikes in this part of the French Maritime Alps. How do you get there? The usual starting point is the Madone de Fenestre sanctuary, reached by road from Saint-Martin-Vésubie and sitting at roughly 1,820 m altitude. From there a loop trail climbs past grazing pastures and rocky outcrops toward the Baisse des Cinq Lacs, a pass above 2,300 m that marks the high point of the circuit and opens up a view over the whole chain of lakes. The full loop covers around 8 km, with about 530 m of elevation gain, and typically takes hikers four to five hours to complete. It's considered a demanding outing, so a reasonable fitness level and proper trekking footwear are worth planning for. What will you find at the lakes? The name "Lacs de Prals" covers a small group of lakes — several accounts count five — scattered across a rocky, glacially carved basin. The water takes on a striking, saturated colour against the surrounding scree slopes and bare granite ridges, and the sparse alpine vegetation that clings to the rock adds bursts of green among the grey. It's a landscape typical of Mercantour's high country: stark, stony, and shaped almost entirely by ice and erosion rather than forest cover. Mercantour National Park is one of the last strongholds of large alpine wildlife in France, and the Prals basin is no exception. Hikers regularly spot chamois grazing on the steep slopes, and the whistling calls of marmots often carry across the valley long before the animals themselves come into view — one of the reasons this route draws so many nature-focused walkers. Who is this hike suited for? Given the altitude, the elevation gain, and the rocky ground near the pass, the Lacs de Prals circuit is best suited to hikers with some mountain experience rather than a casual family stroll. It's more of a full-day outing for people ready to spend several hours on open, high-altitude terrain where weather can shift quickly. In return, it delivers some of the most distinctive glacial scenery in the whole Mercantour range. Frequently Asked Questions Where does the hike to Lacs de Prals start? Most hikers begin at the Madone de Fenestre sanctuary (around 1,820 m), reached by road from Saint-Martin-Vésubie. How long does the hike take and how difficult is it? The loop is roughly 8 km with about 530 m of elevation gain, usually taking four to five hours. The rocky, high-altitude terrain makes it a demanding rather than easy route. How many lakes make up Lacs de Prals? The name refers to a small cluster of glacial lakes within a single rocky basin, with several sources counting five separate bodies of water. What wildlife might you see along the way? Chamois and marmots are commonly observed around the lakes, both typical of the high-altitude fauna found throughout Mercantour National Park. Is this route suitable for beginners? Because of the altitude, the elevation gain, and the rocky sections near the Baisse des Cinq Lacs pass, prior hiking experience and solid fitness are recommended.

Grand Lac de l'Oule
La Salle-les-Alpes
Grand Lac de l'Oule is a high-altitude lake in the Cerces massif in the Hautes-Alpes, sitting at roughly 2,425 metres above sea level on the divide between the Névache valley and the Guisane valley. It falls within the commune of La Salle-les-Alpes, although most hikers approach it from Névache as well. Its turquoise-blue water, framed by jagged rocky ridges, gives the setting a stark, almost lunar character that makes it one of the more distinctive lakes in this corner of the Alps. Where exactly is the lake? The lake sits at the heart of the Cerces massif, between the Névache and Guisane valleys, ringed by rocky crests including the rock formation known as Grand Pierron. The terrain here is classic high-mountain scenery — open alpine pastures, scree slopes, and sparse vegetation above the treeline. Nearby, within the same commune, lies the smaller Lac de Cristol, which many hikers visit on the same outing. How do you get there? The best-known approach starts from the Col du Granon and climbs toward the Col de l'Oule before descending to the lakeshore — a relatively straightforward route across wide pastures, with views over the Cerces massif and the rock walls of Grand Pierron. A second option starts in Névache, from the Fort Ville car park at around 1,585 metres. This longer approach covers about 9.3 km one way with roughly 890 metres of elevation gain, and takes around 5 hours 30 minutes for the round trip. Parts of the trail network here overlap with the GR5c long-distance path, which continues on toward the lakes below the Cristol peak. Is there a longer loop worth doing? Yes — the area around Grand Lac de l'Oule is also the starting point for a longer loop of about 18 km with around 800 metres of elevation gain, linking roughly four mountain lakes above 2,000 metres in a single day out. It suits hikers with solid fitness and some mountain experience who want to turn the visit into a full-day trip rather than a simple there-and-back walk. What makes the lake worth seeing? The lake's main draw is its colour: a turquoise-blue surface set against grey and reddish rock. The jagged skyline and the isolated, stony valleys around it have earned the area comparisons to a western-film backdrop or a lunar landscape. It's a spot that particularly rewards hikers looking for mountain photography and quiet trails away from the busier paths of the Écrins massif just to the south. Frequently asked questions How high up is Grand Lac de l'Oule? The lake lies at around 2,425 metres above sea level. Where's the best starting point for the hike? The two main options are the approach from the Col du Granon, which passes the Col de l'Oule, and the longer route from Névache starting at the Fort Ville car park at about 1,585 metres. How long does the hike take? From Névache, count on roughly 9.3 km one way and about 5 hours 30 minutes round trip, with 890 metres of elevation gain. Hikers wanting to see more of the area can opt for the loop of about 18 km connecting several lakes. Are there other lakes nearby? Yes — the same commune of La Salle-les-Alpes is also home to Lac de Cristol, often visited on the same route. Is the hike difficult? The Col du Granon approach is considered easier and accessible to most hikers, while the longer Névache route and the multi-lake loop require better fitness and some mountain hiking experience.

Lac de Cristol
La Salle-les-Alpes
Lac de Cristol is a mountain lake sitting at 2,245 metres above sea level in the Cerces massif, within the municipality of La Salle-les-Alpes in the Hautes-Alpes department. It lies right on the divide between the Clarée and Guisane valleys, at the meeting point of the Serre Chevalier ski area and the Clarée valley, surrounded by a stark, rocky alpine landscape. Where exactly is the lake? Lac de Cristol sits on the north-facing slope of the Cerces range, above the Serre Chevalier resort area that La Salle-les-Alpes belongs to. It shares its high mountain setting with several neighbouring lakes: Lac de l'Oule (2,425 m) and Lac Rond (2,339 m) lie close by, with the peak of La Gardiole (2,753 m) rising above the group. This cluster of lakes is often listed among the notable high-altitude attractions of the wider Hautes Vallées area, which also includes La Grave, the Clarée valley and Izoard. How do you get there? From Col du Granon The most common and easiest approach starts at Col du Granon, on the Guisane valley side. The route runs partly on marked trail and partly off-trail, and it's easy to turn the walk into a loop that also takes in the neighbouring Lac de l'Oule before returning to the pass. From Névache A second option climbs from the village of Névache in the Clarée valley, following a stretch of the GR5c long-distance trail. This approach is noticeably tougher: it runs through forest, gains roughly 800 metres of elevation, and is generally described as demanding, if scenic. What is there to see? The shores are lined with rhododendrons, which give the setting a distinctive look, especially in summer. Beyond that, the landscape is typical of high alpine lakes above the treeline: bare rocky slopes, open pastureland, and views toward the surrounding peaks of the Cerces massif. The lake is also mentioned in some sources as a spot used by anglers fishing high-altitude waters, though that's worth checking locally before planning a fishing trip. Who is the hike suited for? Trails leading to Lac de Cristol are rated as moderate to difficult — this isn't a beginner's stroll, particularly on the Névache side. The loop from Col du Granon is generally considered the more approachable option and is a popular summer choice for visitors based in the Serre Chevalier area. Frequently asked questions How high up is Lac de Cristol? The lake sits at an altitude of 2,245 metres. Where's the best place to start the hike? The simplest and most commonly recommended access is from Col du Granon, on the Guisane valley side. A harder alternative climbs through forest from Névache, following the GR5c trail. Can the visit be combined with other lakes? Yes — Lac de l'Oule and Lac Rond lie in the immediate vicinity, making it possible to plan a longer loop covering several lakes of the same range. Is the trail difficult? The hike is considered demanding, especially the Névache approach with its roughly 800 metres of climbing. The Col du Granon route is usually described as more accessible, though it still runs partly off marked paths. What does the lake look like? Lac de Cristol lies in a rocky, high-mountain setting, its shores fringed with rhododendrons, with views toward the surrounding peaks, including the dominant Gardiole above.

Lac de Roy
Taninges
Lac de Roy is a small glacial lake sitting at roughly 1,660 metres above sea level, tucked into the alpine pastures of the Praz de Lys Sommand area. It belongs to the commune of Taninges, in the Haute-Savoie department, in the Auvergne-Rhône-Alpes region, about 2 kilometres west of the Praz de Lys ski resort. It's the kind of spot that rewards very little effort with a view that would normally take a much harder climb to earn. Where exactly is the lake? The lake lies on the open grazing pastures surrounding Praz de Lys, right where several mountain paths converge. The terrain around it is gentle and unobstructed, so the water comes into view well before you reach the shore. How do you get there? The most common approach starts in Praz de Lys and takes about half an hour one way. The path is wide with very little elevation gain, which makes it manageable for families with young children or anyone without much hiking experience. An alternative route begins in Sommand, following the road toward Col de la Ramaz — a pass at 1,619 metres — before descending toward the water. What is there to see along the way? Because the landscape is so open, the Mont Blanc massif is visible for much of the walk, which is one of the main reasons this short outing feels worthwhile. In summer, cows graze the meadows around the lake, and marmots are a frequent sight, especially in the morning or late afternoon when they're most active. Can the walk be extended? Lac de Roy sits at a crossroads of several trails, so hikers looking for more can continue on toward Pic de Marcelly, a peak reaching 1,999 metres. From the summit, the view opens into a full 360-degree panorama covering the valley and the surrounding ranges — a natural extension for anyone who finds the lake walk too short on its own. When is the best time to visit? The area around the lake is freely accessible from 1 May to 30 November. During the summer holiday season the trail can get busy, so it's worth timing a visit for the morning or later in the afternoon, when the crowds thin out. Who is this spot suited for? Given the short approach and minimal elevation gain, Lac de Roy works well as a family destination, but it also serves as an easy waypoint for longer treks through the Praz de Lys Sommand massif. There's little in the way of built infrastructure here — the appeal comes from the scenery, the quiet, and the view toward Mont Blanc rather than any tourist amenities. Frequently asked questions How high up is Lac de Roy? The lake sits at an altitude of around 1,660 metres. How long does it take to reach the lake? About 30 minutes of gentle walking from Praz de Lys. Is the trail difficult? No, the path is wide with minimal elevation gain, suitable for families with children. Can the hike be extended? Yes, from the lake you can continue up to Pic de Marcelly (1,999 m) for a 360-degree panorama. When is the lake area open to visitors? The site is freely accessible from 1 May to 30 November, though it gets crowded during summer midday hours. What wildlife might you see nearby? Cows graze the surrounding pastures in summer, and marmots are commonly spotted in the meadows.

Lac de la Lande
Le Régit
Lac de la Lande is a man-made reservoir in the Vosges mountains, sitting at roughly 1,060 meters above sea level at the foot of the Kastelberg massif, within the municipality of La Bresse. It belongs to a cluster of lakes around La Bresse and Gérardmer — alongside Lac des Corbeaux and Lac de Lispach — and lies inside the Ballons des Vosges Regional Nature Park, making it a regular stop on longer lake-hopping hikes through the area. Is the lake natural? No. Before the dam, the site held a natural peat bog known as the Faignes de la Lande. Construction started on 1 December 1982, the reservoir went into service on 10 December 1983, and it was formally inaugurated on 29 May 1984. The project drew opposition from environmental groups at the time, since it meant flooding a valuable peat bog ecosystem. As compensation, the municipality of La Bresse pushed for the protection of the Machais peat bog, which was formally classified as a nature reserve in 1988. How big is the reservoir, and what is it used for? The dam itself is 70 meters high and 330 meters long. It holds back around 700,000 m³ of water across a surface area of 10.5 hectares, with a maximum depth of 13 meters. A Pelton turbine rated at 2,090 kW sits at the structure. The water serves three purposes: electricity generation, drinking water for part of La Bresse's supply network, and snowmaking for the La Bresse–Hohneck ski resort. That last function explains why locals often talk about the lake in the same breath as the ski slopes, even though the surrounding forest makes it feel far removed from any resort infrastructure. What is the hiking loop like? The classic route circles the entire lake, covering about 5 km and taking around 2 hours at a moderate pace. Most hikers start near the Vologne chairlift station, head toward the Piste Bourvil, climb up past the top of the Vologne lift, then descend to the lakeshore. From there the path follows the southern bank, crosses the top of the dam, and closes the loop along a northwestern stretch back to the start. There is some elevation gain along the way, so proper walking shoes are worth having even though the trail itself is not technical. When is the best time to visit? May through September is the recommended window, when trails are dry and the vegetation around the reservoir is at its fullest. In winter the surrounding slopes switch over to skiing, tying directly back to the lake's role as a water reserve for the resort's snow cannons. Frequently asked questions How long does it take to walk around Lac de la Lande? The full loop is about 5 km and takes roughly 2 hours at a moderate walking pace. Is Lac de la Lande a natural lake? No — it is an artificial reservoir put into service in 1983, built over a former peat bog. What other lakes are nearby? Lac des Corbeaux and Lac de Lispach are both close by in the La Bresse area, and together with Lac de la Lande they form a popular circuit for visitors touring the Vosges lakes. What is the dam used for? Hydroelectric power (a 2,090 kW Pelton turbine), drinking water for part of La Bresse, and snowmaking for the La Bresse–Hohneck ski area. Can you swim in the lake? Available sources do not describe an organized swimming area at Lac de la Lande — it is primarily a hiking and scenic destination rather than a bathing lake.

Lac Achard
Chamrousse
Lac Achard is a mountain lake sitting at roughly 1,917 metres of altitude in the Belledonne massif, within the municipality of Chamrousse in the Isère department of the French Alps. It's one of the most accessible alpine lakes in the area, which makes it a favourite for families and for anyone after a short but rewarding walk with a genuine high-mountain feel. Where is the lake located? Lac Achard sits on a plateau in the upper part of the Chamrousse ski resort, close to two of the resort's main access points: Chamrousse 1750 (Roche-Béranger) and Chamrousse 1600 (plateau de l'Arselle). Its coordinates are approximately 45.114°N, 5.901°E. Chamrousse itself lies at the tip of the Belledonne range, about 30 km from Grenoble. How do you get to Lac Achard? The most popular approach starts from Roche-Béranger (Chamrousse 1750) and takes around an hour at a relaxed pace, which is why it's often chosen by families with children. A second route climbs from the plateau de l'Arselle (Chamrousse 1600), but it's steeper and better suited to hikers with a bit more stamina. In summer the path requires no special equipment, while in winter the area around the lake becomes a popular destination for snowshoe outings. Are there any restrictions around the lake? Lac Achard lies within a designated Sensitive Natural Area (ENS) known as "Plateau de l'Arselle et lac Achard," and the site also falls inside a Natura 2000 zone. As a result, several activities are banned here: lighting fires, collecting firewood, camping, foraging for plants, fishing, and swimming — the swimming ban applies to dogs as well. These rules exist to protect the fragile ecosystem of the high-altitude lake and the surrounding peat bogs. What views and onward routes are worth knowing about? The lake's distinctive, well-rounded shape is best appreciated from the Col de l'Infernet and from the Croix de Chamrousse, the resort's highest point at around 2,250 metres. On a clear day, both spots offer views across to the Taillefer massif. Lac Achard also works as a natural waypoint on a longer route that continues past the Lacs Robert all the way up to the Croix de Chamrousse summit — a popular option for hikers wanting to string together several of Belledonne's highlights in one outing. What is Chamrousse best known for? Chamrousse is a ski resort spread across three villages — Recoin, Roche-Béranger and l'Arselle — and it holds a distinctive place in Olympic history: it was the only French resort to host every alpine skiing event of the 1968 Winter Olympics in Grenoble. It was on the slopes of Chamrousse that Jean-Claude Killy won three gold medals and Marielle Goitschel took one of her own. That Olympic legacy remains a defining part of the resort's identity and is still proudly highlighted to visitors today. Frequently asked questions How long does it take to reach Lac Achard? From Roche-Béranger (Chamrousse 1750), the walk takes about an hour at a moderate pace. Can you swim in the lake? No. Because the area has protected status, swimming is banned, along with fishing, camping, and lighting fires. Is the hike suitable for children? Yes, the approach from Roche-Béranger is considered easy and is popular with families. Can the lake be visited in winter? Yes, the area around Lac Achard is a well-known destination for snowshoe outings during the winter season. What can you see from the nearby Col de l'Infernet? The lake's characteristic shape, and on clear days, the Taillefer massif in the distance.

Lac des Corbeaux
La Bresse
Lac des Corbeaux is a small mountain lake tucked into the Vosges range, within the commune of La Bresse in eastern France. Sitting at roughly 900 metres above sea level and covering about 9.1 hectares, it is one of the few natural lakes on the Lorraine side of the massif, making it a distinctive stop for anyone exploring this part of the Vosges. How did the lake form? The basin occupies an old glacial cirque, a bowl-shaped hollow carved out by a glacier during the last Ice Age. As the ice retreated roughly 10,000 years ago, water collected in the depression left behind. The steep, rocky slopes that ring the lake today are a direct legacy of that glacial carving, giving the site its enclosed, amphitheatre-like feel. Where does the name come from? Despite the literal translation ("lake of the crows"), local tradition traces the name back to the French word "courbées," meaning curved or bent - a reference to the steeply curving slopes that surround the water. Over time, "courbées" is thought to have shifted in pronunciation toward the similar-sounding "corbeaux," giving the lake its current name. What can visitors do at the lake in summer? Swimming is permitted during the summer months, though the water stays on the cool side, typically around 18-20°C. Campfires and camping along the shore are not allowed, which helps keep the setting undisturbed. The lake also supports fishing, with trout and Arctic char living in its waters - anglers need a local fishing permit before casting a line. How do you get there, and how long is the walk? The lake sits about 5 km from the centre of La Bresse, reached via the D34 road, with free parking available on site. A gentle loop trail circles the water, covering around 3 km and taking roughly one to one and a half hours - an easy option suitable for families. More ambitious walkers can extend the outing toward the Hohneck summit or a nearby waterfall. Did the lake ever serve an industrial purpose? Since 1905, the lake has fed a small 140 kWh turbine operated by La Bresse's municipal power utility. The electricity it generated was notably used to light the local church on Christmas night - a small but memorable piece of the lake's history as a working part of the community rather than just a scenic backdrop. When is the best time to visit? Summer draws visitors looking to swim and stroll along the shaded shoreline. Spring and autumn bring quieter trails and more vivid colours on the surrounding slopes. In winter, the extended path leading to the rocky viewpoint above the lake can become impassable, so it is worth checking conditions locally before setting out. Frequently asked questions How high up is Lac des Corbeaux? The lake lies at an altitude of around 900 metres, within the commune of La Bresse in the Vosges. Can you swim in the lake? Yes, swimming is allowed in summer, though the water remains cool at around 18-20°C. Campfires and camping are prohibited. How long does it take to walk around the lake? The easy loop trail around the lake is about 3 km long and takes between one and one and a half hours. Where does the lake's name come from? It likely derives from "courbées" (curved), referring to the steep slopes surrounding the water, which over time evolved into "Corbeaux." Is fishing allowed at Lac des Corbeaux? Yes, the lake holds trout and Arctic char, but a local fishing permit is required.

Lac de l'Aréna
Roquebrune-sur-Argens
Lac de l'Aréna is a man-made lake in the commune of Roquebrune-sur-Argens, in the Var department, sitting at the foot of the Rocher de Roquebrune between Fréjus and the Gulf of Saint-Tropez. Once a working gravel quarry, it has become one of the region's most popular outdoor destinations, valued equally for its wildlife and its watersports. Where did the lake come from? The site was quarried for sand and gravel by the Perrin family business, which began operations there in 1962. Aggregate dredged from the nearby Basses Roques pit was shipped downriver, and dozens of workers handled extraction, sifting and washing of the material, using both open-pit methods and a dredger working underwater. The quarry closed in the late 1980s, after which the abandoned pit filled with water from the Argens river, forming the roughly 30-hectare lake seen today. What is there to see and do around the lake? The lake now serves two purposes at once: nature reserve and recreation ground. Its western shore, lined with reed beds, gives shelter to nesting waterbirds and provides spawning grounds for fish, while the sandy banks are used by European bee-eaters to dig their nesting burrows. These features have earned the site Natura 2000 protected status. From May to September, a watersports base operates on the lake, with room for up to 1,500 visitors at a time. It includes a 3,000-square-metre floating inflatable park with more than 250 structures, an XXL slide and an obstacle course graded for different skill levels. Visitors can also try water-skiing, windsurfing and pedal boating. Can you walk around the lake? A 3.5-kilometre footpath circles the lake, taking around an hour and a quarter to complete. The full loop opened in 2023, once the last stretch of the trail was finished. The path is flat and smooth enough to be covered with an all-terrain stroller, making it a straightforward outing for families. Does the lake host events? In summer the lake doubles as a concert venue: a temporary floating stage is set up on the water for evening shows mixing French chanson, pop and electronic music. Frequently asked questions Where exactly is Lac de l'Aréna? In the commune of Roquebrune-sur-Argens, Var department, at the foot of the Rocher de Roquebrune, between Fréjus and the Gulf of Saint-Tropez. Is the lake natural? No — it is an artificial lake created when the Argens river flooded a former gravel quarry that operated from 1962 until the late 1980s. How big is the lake? Around 30 hectares. Can you swim and do watersports there? Yes, a supervised watersports base runs from May to September, with an inflatable park and rental equipment for water-skiing, windsurfing, kayaking and pedal boats. Is there a walking trail around the lake? Yes, a 3.5-km loop (about 1 hour 15 minutes) fully opened in 2023 and suitable for all-terrain strollers.

Lac de Nino
Corte
Lac de Nino is a mountain lake in Haute-Corse sitting at 1,743 metres above sea level, in the range of peaks surrounding Corte. It is not the island's largest body of water, but it ranks among Corsica's bigger natural freshwater lakes, and it sits noticeably lower than many other alpine lakes on the island. Its glacial origin is still visible today in the smooth, rounded terrain around it and the shallow basin the water now fills. Where exactly is the lake, and how do you get there? The lake lies deep in the mountains within the commune of Albertacce, in the range stretching between the Col de Vergio and the Niolo valley, not far from Corte and Lake Calacuccia. No road reaches the shore itself — the only way in is on foot, which is very much part of the experience. The classic starting point is the old forest house at Poppaghia, just off the D84 road linking the Col de Vergio with Calacuccia and Albertacce. From there the round trip covers roughly 10 kilometres with about 720-730 metres of elevation gain, taking most hikers somewhere between 5 and 7 hours depending on pace and trail conditions. The first stretch runs through forest; the second, steeper section climbs above the tree line onto the open highland plateau where the lake sits. What are the pozzines everyone talks about? The lake is ringed by pozzines — wide, boggy alpine meadows that formed where smaller glacial lakes once stood before gradually filling in with sediment and vegetation, leaving behind only scattered pools and thin channels of open water. In summer these meadows turn a deep, saturated green, crossed everywhere by small streams, and the effect is unlike almost anywhere else on the island. It's this combination of high plateau, soft wetland grass, and surrounding granite peaks that gives the site its distinctive look. Why are there horses and cows just wandering around? One of the most talked-about sights at Nino is the free-roaming livestock — horses, cows, and occasionally pigs — grazing loose across the pozzines with no shepherd in sight. The animals spend the whole summer here, finding both food and water in the wetland grass, and their presence is entirely unsupervised. It gives the plateau an unusually wild, half-tamed character even though it lies right at the geographic heart of Corsica. Why do hikers on the GR20 rate this section so highly? Lac de Nino sits directly on the GR20, one of Europe's toughest long-distance trails, which runs the length of Corsica's mountain spine. The stretch passing the lake, just before the Manganu refuge, is often singled out as one of the most scenic parts of the entire route, largely because of the sharp contrast between the rocky high country and the lush, waterlogged pozzines below. Frequently asked questions Can you swim in Lac de Nino? The lake is a popular stop in summer, but it functions mainly as a viewpoint and rest area along the trail rather than a swimming spot — the water tends to be shallow and cold, and the surrounding ground is marshy. Is the hike suitable for children or beginners? Given the distance, the elevation gain, and long stretches without shade, this is not a casual family walk; it requires reasonable fitness, though experienced hikers do bring children along without major issues. When is the best time to visit? Summer is the best window, when the pozzines are fully green and the trail has dried out. Earlier in the season the ground can be extremely waterlogged, and snow covers the area in winter. Are the grazing animals dangerous? The horses and cows on the pozzines are used to hikers passing through and generally keep their distance, but visitors are advised not to approach or feed them.

Lac de Remoray
Labergement-Sainte-Marie
Lac de Remoray is a small glacial lake in the Doubs department, straddling the communes of Labergement-Sainte-Marie and Remoray-Boujeons in the Bourgogne-Franche-Comté region of eastern France. It sits in the upper Doubs valley, just south of the larger Lac de Saint-Point — a separate lake with a similar name that lies in the same valley, so the two are easy to confuse but should not be mixed up. Where exactly is the lake? Lac de Remoray lies in the Jura foothills, close to the Swiss border, surrounded by meadows, forest and wetland typical of this part of France. Since 1980, the lake together with its surrounding marshes and peat bog has formed the Lac de Remoray National Nature Reserve, covering roughly 330 hectares. What makes this reserve stand out? The reserve brings together several very different habitats within a small area: the glacial lake itself, extensive wetlands, an acidic peat bog, farmed meadows and patches of forest. This close juxtaposition of habitats gives the site an unusually high level of biodiversity for the region. The peat bogs were historically altered by peat cutting, forestry and farming, but restoration work carried out in recent decades has successfully brought back their natural wetland character. What wildlife can you see around the lake? Remoray has long been known for its exceptional birdlife: 242 species have been recorded in the reserve, with 110 of them nesting there. The most notable residents include common snipe and water rail, alongside the much rarer corncrake and spotted crake, both tied to wet meadows and reedbeds. Insects are equally rich — 66 butterfly species have been catalogued, including some found only on peat bogs, along with 48 dragonfly species, among them all four French species of Leucorrhinia whiteface dragonflies. The sphagnum-covered acidic bogs support bog rosemary and cranberry, and the reserve is home to four species of carnivorous plants: common butterwort, round-leaved sundew and two species of bladderwort. How can you visit the reserve? Visits start at the Maison de la Réserve in Labergement-Sainte-Marie, a visitor centre with six exhibition rooms across 500 square metres, dedicated to the region's natural habitats and to the lake itself. From there, a marked interpretive trail leads down to the lakeshore, open to visitors without entering the strictly protected core of the reserve. During the February half-term and the July-August school holidays, the centre organises guided outdoor outings to observe wildlife in its natural setting. The best time to walk the trail is toward evening, when the setting sun reflects across the water and birds return to roost at the nearby heronry. Frequently asked questions Can you swim in Lac de Remoray? The lake lies within a nature reserve where bird and plant protection takes priority, so open access to the shore and swimming are not part of the usual visitor experience. Is entry to the reserve free? Walking the interpretive trail along the lake is open to the public, while the exhibitions at the Maison de la Réserve require an admission fee. How is it different from Lac de Saint-Point? They are two neighbouring but distinct lakes in the same Doubs valley — Lac de Remoray is considerably smaller and lies entirely within a protected nature reserve. When is the best time to visit? Spring and summer are best for spotting nesting birds and bog plants in flower, while early evening offers the clearest views across the lake.

Lac de la Sitre
La Combe-de-Lancey
Lac de la Sitre is a small mountain lake in the Belledonne range, sitting at 1,952 metres above sea level within the commune of La Combe-de-Lancey, in the Isère department of France. It occupies a rocky cirque below the Pointe de la Sitre, surrounded by the bare ridgelines and alpine terrain typical of this part of Belledonne. Where is the lake located? The lake lies in the upper reaches of the valley above La Combe-de-Lancey, on the flank of the Belledonne range that overlooks the Grésivaudan valley. The commune's territory spans every alpine level found in the massif, from forest at the bottom to mountain pasture and bare rock higher up. Lac de la Sitre sits close to other lakes of the same chain, including Lac du Crozet and Lac du Loup, which means several bodies of water can be combined into a single outing. How do you get to Lac de la Sitre? Most hikers start from La Combe-de-Lancey itself. The path climbs through forest before opening onto mountain pasture, passing the Pré du Mollard refuge along the way. The first stretch up to the refuge is the steepest part of the walk; beyond it the gradient eases across open pastureland. From the Habert de la Sitre, walkers can branch off toward the neighbouring Grande Sitre lake or continue on a loop that takes in the Col du Loup, Lac du Loup and Lac du Crozet. That loop involves no technical climbing, though its length and elevation gain call for a reasonable level of fitness. Hikers after a longer day can continue up to the Pointe de la Sitre, the peak overlooking the lake, which opens onto views of the Grésivaudan valley and the Grand Pic de Belledonne. What should you know before setting out? The route runs through high mountain terrain, where weather can shift quickly and shaded sections can hold snow well into late spring. Sturdy hiking boots and a check of the forecast beforehand are standard practice for any outing in Belledonne. Summer is the most reliable season to visit, when the trails are clear and fully passable. Frequently asked questions How high up is Lac de la Sitre? The lake sits at 1,952 metres above sea level, in the Belledonne massif. Where should you start the hike? La Combe-de-Lancey is the natural starting point. From there the trail climbs through forest and pasture to the Pré du Mollard refuge before reaching the lake. Is the trail technically difficult? The loop connecting Lac de la Sitre with the nearby Lac du Loup and Lac du Crozet involves no technical climbing, though its distance and elevation gain require decent fitness. The initial climb to the Pré du Mollard refuge is the steepest section. Are there other lakes nearby worth visiting? Yes — Lac du Crozet and Lac du Loup lie in the same part of Belledonne, making it easy to plan a longer hike linking several lakes in one trip. Can you see other Belledonne peaks from the trail? Yes. The climb toward the Pointe de la Sitre opens onto views of the Grésivaudan valley and the Grand Pic de Belledonne, the massif's highest summit.

Lac Saussat
Oô
Lac Saussat is a mountain lake in the commune of Oô, in the Haute-Garonne department of the French Pyrenees, not far from the spa town of Bagnères-de-Luchon. It sits at roughly 1,920 to 1,940 metres above sea level, on the same high-altitude circuit that draws hikers to the well-known Lac d'Oô. Where exactly is it? The lake belongs to a chain of alpine lakes strung along the valley of the Neste d'Oô. It lies between Lac d'Espingo, downstream, and Lac du Portillon, further upstream near the Spanish border. Lac Saussat receives inflow from Lac du Portillon via the Neste d'Oô, as well as some water from the nearby Lac Glacé d'Oô, and in turn feeds Lac d'Espingo further down the valley. Its shape is irregular, stretching up to about 500 metres north to south and 200 metres east to west, for a surface area of roughly 6 hectares. How do you get there? The most direct approach starts at Granges d'Astau, a small hamlet at around 1,130 metres in the commune of Oô. A broad, easy path climbs first to Lac d'Oô, one of the Pyrenees' best-known lakes, fed by a 275-metre waterfall that tumbles down the valley headwall. Beyond that lake the trail turns considerably steeper, winding up switchbacks for roughly 400 metres of additional ascent to reach Lac d'Espingo. From there, a final, much shorter stretch of about fifteen minutes leads to Lac Saussat, through terrain that grows progressively more rocky and remote. Hikers can also approach from Bagnères-de-Luchon on a longer route. What makes the lake distinctive? Compared with the busier Lac d'Oô, Lac Saussat feels far quieter and more remote. Its water is notably clear, with a deep greenish tint. The surrounding landscape marks a transition from mid-mountain pasture to a starker, high-mountain environment, with bare rock and views toward the peaks that ring the valley. The name itself comes from the Béarnese Occitan word "saussat", meaning a place planted with willows. When should you go? The route is generally only practicable from June to October, once snow has cleared from the higher sections. Outside that window, reaching the lake requires winter mountaineering experience and equipment, given the altitude and the steep approach beyond Lac d'Espingo. Frequently asked questions Is Lac Saussat connected to Lac d'Oô? Yes — they belong to the same chain of lakes in the valley, with Lac Saussat lying higher up the same trail, above Lac d'Espingo and below Lac du Portillon. Can you fish at Lac Saussat? Fishing is allowed in season, under the applicable local regulations. How long does the full hike take from Granges d'Astau? Timing varies with fitness and pace, but the route runs through three stages: a gentle climb to Lac d'Oô, a much steeper 400-metre ascent to Lac d'Espingo, and a final short fifteen-minute stretch to Lac Saussat. Is the trail difficult? The first section to Lac d'Oô is wide and easy; the climb beyond it, up to Lac d'Espingo and then Lac Saussat, is considerably harder, with steep switchbacks that demand reasonable fitness. When is the lake accessible to visitors? Essentially only from June to October, once the upper sections of the trail are free of snow.

Lac de Villeneuve-de-la-Raho
Villeneuve-de-la-Raho
Lac de Villeneuve-de-la-Raho is a man-made lake roughly 10 km north of Perpignan, in the Pyrénées-Orientales department of French Catalonia. Its waters spread across the communes of Villeneuve-de-la-Raho, Bages, Montescot and Pollestres, taking their name from the first. The site combines the practical role of a water reserve with that of a popular recreation area and a refuge for waterbirds. How did the lake come to exist? A natural pond called Étang de Barrià, covering around 150 hectares, once occupied this spot. Considered of little use, it was drained in 1854. The idea of a reservoir only returned in the 20th century: retention works were built here in the 1970s, and the basin was flooded again in 1977. The project was designed to secure water for irrigating nearby farmland, to support fire-fighting reserves, and to help supply drinking water to the Roussillon plain. How large is the area around the lake? The complex is made up of three separate basins with a combined water surface of about 230 hectares, surrounded by close to 50 hectares of maintained green space, including planted pine woods. That scale makes Lac de la Raho one of the larger artificial lakes in the region and a significant feature of the local water landscape. Is it a bird reserve? Yes. Wildlife settled on the site remarkably quickly after it was flooded, which led authorities to place part of the area under protection. In 1983 the Groupe Ornithologique du Roussillon (GOR) began regular bird monitoring, and in 1985 a 14-hectare section was formally designated an ecological reserve. The area is listed as a ZNIEFF (zone of special ecological interest) and a ZICO (Important Bird Area). The lake serves as a stopover point for migratory birds, and around 200 bird species have been recorded in and around the reserve. What can visitors do there? Lac de la Raho is a favourite outing for residents of Perpignan and the surrounding area. In summer, from June to August, a supervised beach with a lifeguard post is open for swimming. Paths around the basins are laid out for running and walking, along with a fitness trail with outdoor exercise stations. Cyclists and mountain bikers can ride the full loop around the lakes, a 6.7 km circuit. On the water, visitors can row, sail or paddle a canoe or kayak, and anglers will find spots for fishing. Pétanque is another popular pastime here. Access to the site is free of charge and there are no fixed opening hours, making it an easy stop for a day trip. Frequently asked questions Is Lac de Villeneuve-de-la-Raho a natural lake? No, it is an artificial reservoir, built on the site of the former Étang de Barrià, which was drained in 1854 and reflooded in 1977. How far is the lake from Perpignan? About 10 km north of central Perpignan, in the Pyrénées-Orientales department. Can you swim there? Yes, a supervised beach with a lifeguard post operates in summer, from June to August. Is it a nature reserve? Yes, a 14-hectare section has been protected as an ecological/ornithological reserve since 1985, classified as ZNIEFF and ZICO, with around 200 bird species recorded. What activities are available besides swimming? Running, walking, cycling on a 6.7 km loop, fishing, pétanque, and water sports such as rowing, sailing and kayaking. Is entry free? Yes, access to the lake area is free and there are no set opening hours.

Lac de Goria
Corte
Lac de Goria is a small glacial lake tucked into the upper reaches of the Restonica valley in the mountains of Corsica, not far from the town of Corte. Sitting at an altitude of 1,852 metres, it covers a modest surface area of around 4 hectares, making it one of the smaller lakes in this part of the island. Like its neighbours, it was carved out by glacial activity thousands of years ago, leaving behind the rocky, bowl-shaped cirque that holds it today. Where exactly is the lake? Goria lies in Haute-Corse, in the mountain range that frames the Restonica valley, one of Corsica's best-known hiking destinations. The lake sits higher up and further into the mountains than the valley's two more famous lakes, Lac de Melo (1,711 m) and Lac de Capitello (1,930 m), and is effectively the next stop for hikers willing to push beyond them. How do you get to Lac de Goria? Most visitors start from the Restonica valley, reached by road from Corte. Following storm damage in November 2023, part of that road was washed out, and vehicle access is now limited to the first six kilometres of the valley, as far as Tuani. The former starting point at the Grotelle sheepfolds is therefore harder to reach directly, and many hikers now begin lower down, near Frassetta (around 900 m), which adds extra distance and time to the whole outing. The path toward Lac de Melo splits into two options: an easier route along the left side of the valley, and a steeper one on the right that crosses a rocky passage equipped with chains and ladders. Reaching Goria means continuing past both Melo and Capitello, further up into the high mountain cirque — a stretch that calls for a reasonable level of fitness and some hiking experience. What sets Goria apart from Melo and Capitello? Melo and Capitello are the valley's star attractions and draw large numbers of visitors, especially in summer, when the trail can get crowded. Goria sits higher and further along the route, and reaching it takes noticeably more effort, which keeps visitor numbers much lower. For hikers looking to get away from the crowds gathered around the two better-known lakes, Goria offers a quieter alternative just a bit further up the valley. What should you know before setting out? Weather at this altitude can change quickly, even in summer, and the terrain around Goria is rocky and typical of high-mountain cirques, so proper hiking boots and a reasonable fitness level matter here. It's also worth keeping in mind that, since the access road was damaged, the overall hike has become longer than it used to be a few years ago. Frequently Asked Questions How high up is Lac de Goria? The lake sits at 1,852 metres above sea level, higher than both Lac de Melo and Lac de Capitello nearby. Can you drive all the way to the lake? No. Road access ends at Tuani, six kilometres into the Restonica valley; from there, the rest of the journey is on foot. Is the hike difficult? It requires decent fitness, since it continues past two other lakes through rocky, high-altitude terrain. One of the approach routes to Melo includes a section with chains and ladders. How is Goria different from Melo and Capitello? It's smaller, sits higher up, and sees far fewer visitors — a good option for those seeking a quieter spot away from the crowds. Can you visit all three lakes in one trip? Yes. The trails to Melo, Capitello and Goria connect, so it's possible to see all three lakes on a single outing, provided you have the time and stamina for it.

Grand lac de Rinoso
Corte
Grand lac de Rinoso is a glacial mountain lake sitting at roughly 2065 metres above sea level, in the upper reaches of the Restonica valley, within the Corsica Regional Natural Park (Parc naturel régional de Corse), a dozen or so kilometres from Corte. It pairs with the smaller, higher-lying Petit lac de Rinoso (around 2082 m) — together the two sit in the bare, rocky surroundings of the Monte Rotondo massif and rank among the quieter lakes of this part of Corsica. Where exactly is the lake? The lake occupies a stony high-altitude basin in the upper Restonica, along the route linking the Bergeries de Grotelle area with the Bocca a Soglia pass. It is classic Corsican interior scenery — granite ridges, sparse vegetation, and small, cold lakes fed by melting snow, reachable only on foot. How do you get there? The traditional starting point is the Bergeries de Grotelle, at the end of the road running up the Restonica valley. Severe storms in November 2023 damaged the road beyond the Tragone bridge, making it impassable, so the current trailhead is the Frassetta car park. A shuttle bus runs there from Corte between 2 May and 30 September. The path to the Rinoso lakes is waymarked only as far as the junction with the Lac de Melo trail; beyond that, hikers follow cairns. The climb is steady and steep in places but not technically demanding. On reaching the lakes, you pass the smaller, higher Petit lac de Rinoso first, then the Grand lac de Rinoso about 200 metres further on. The return can be varied by looping back over the Bocca a Soglia pass. How does it compare with Lac de Melo and Lac de Capitello? The Restonica valley is best known for Lac de Melo and Lac de Capitello, both easier to reach and correspondingly far busier in summer. The Rinoso lakes sit up a side branch of the valley and require a longer, more demanding approach, which keeps visitor numbers much lower. It is the kind of spot suited to travellers after quiet high-altitude Corsica rather than crowds — in exchange for a longer walk and less obvious waymarking. When is the best time to go? Summer is the most practical season, once the snow has cleared and the Corte–Frassetta shuttle is running (early May through the end of September). Earlier in the season, snow can still linger around the lakes and the cairn-marked stretch becomes harder to follow. Plan for a full day out, check the weather forecast beforehand, and wear proper hiking boots — the terrain is rocky and offers little shade. Frequently Asked Questions How high up is the Grand lac de Rinoso? About 2065 metres above sea level; the neighbouring, smaller Petit lac de Rinoso sits a little higher, around 2082 metres. Where does the trail to the Rinoso lakes start? Currently at the Frassetta car park, served by a shuttle bus from Corte from 2 May to 30 September — the traditional Bergeries de Grotelle starting point has been unreachable since the road was damaged by the November 2023 storms. Is the hike difficult? The climb is steady and steep in parts but mostly non-technical; the main challenge is navigation, since waymarking gives way to cairns past the Lac de Melo junction. Are the Rinoso lakes as busy as Melo and Capitello? No — they lie along a longer, less clearly marked side route, which makes them considerably quieter than the heavily visited Lac de Melo and Lac de Capitello in summer.

Lac de Scapuccioli
Corte
Lac de Scapuccioli is a high-altitude lake in the Monte Rotondo massif in Corsica, sitting at 2,338 metres above sea level in Haute-Corse, in the upper Restonica valley near Corte. It neighbours the Lac de Bellebone and the Lac de Cavacciole (2,015 m) — together, Scapuccioli and Cavacciole feed the Ruisseau de Cavacciole, which flows down into the Restonica river and, further along, forms the well-known Grotelle waterfalls. How do you get to Lac de Scapuccioli from Corte? The starting point is Corte, from where the D623 road climbs about 16 km up the Restonica valley to the Bergeries de Grotelle, the sheepfolds where the paved road ends and the hiking trail begins. In summer, parking at Bergeries de Grotelle is a paid car park, and spaces can fill up quickly around midday. What is the hike to the lake like? From Bergeries de Grotelle, the route follows the Cavacciole stream valley upward, crossing alder thickets and scree slopes while keeping to the left bank of the stream. This is a far quieter corner of the Restonica valley than the well-trodden path to Lac de Melo and Lac de Capitello. Near Lac de Scapuccioli itself there is no marked trail — only a scattering of cairns to guide the way — so reaching the lake calls for solid off-trail mountain hiking experience. Who is this hike suited for? The approach to Lac de Scapuccioli suits experienced mountain hikers who are comfortable moving over scree and unmarked ground. The lake sits along a route that continues toward the summit of A Maniccia (2,496 m), which is why it is often visited as one stage of a longer, full-day outing that combines both the Cavacciole and Scapuccioli lakes. How is it different from the other Restonica valley lakes? The upper Restonica valley holds several glacial lakes, and Lac de Scapuccioli is sometimes confused with the far better-known Lac de Melo and Lac de Capitello, which sit lower down and are much easier to reach from Bergeries de Grotelle. Scapuccioli, together with its neighbours Cavacciole and Bellebone, lies higher up in a quieter side valley and demands a longer, more demanding approach with no waymarked path. Frequently asked questions How high up is Lac de Scapuccioli? The lake sits at 2,338 metres above sea level, in the Monte Rotondo massif. Where should you start the hike? From Corte, take the D623 road to Bergeries de Grotelle (about 16 km), where the walk up the Cavacciole stream valley begins. Is the trail marked? The final stretch near the lake has no marked trail — only scattered cairns — so it requires real off-trail hiking experience. Is this the same lake as Lac de Melo or Lac de Capitello? No. Melo and Capitello lie lower down and are much easier to access, while Scapuccioli, along with Cavacciole and Bellebone, sits higher up in a less-visited part of the Restonica valley. Where does the trail lead beyond the lake? Toward the summit of A Maniccia (2,496 m), allowing hikers to combine both the Cavacciole and Scapuccioli lakes into one longer mountain outing.

Lac de Melu
Corte
Lac de Melo (also spelled Lac de Melu) is a glacial lake tucked into the Restonica gorges above Corte, in the Haute-Corse mountains of Corsica. Formed in a rock basin carved by a glacier, it sits at roughly 1,710 metres above sea level, covers close to 6.5 hectares, and reaches a depth of around 20 metres. The Restonica river, which later flows through Corte itself, begins here. Where exactly is the lake? Melo lies along the approach toward Monte Rotondo, at roughly 42.213° N, 9.022° E. It is the lower of two well-known lakes in this valley: a smaller lake, Capitello, sits in a higher rock cirque and is usually reached after a stop at Melo. How do you get there? The starting point used to be the Grotelle sheepfolds, reached by a mountain road running up the Restonica valley from Corte. Since storm damage in November 2023, the bridge near Tragone has been impassable, so the drivable section now ends earlier, at Frassetta, and the rest of the approach is on foot. Between May and September, a shuttle bus runs from Corte to Frassetta, which helps given how limited parking is in the narrow valley. How long does the hike take? Walking from Frassetta up to the former Grotelle car park and back takes about 5 hours. Reaching Lac de Melo itself, with the longer approach on foot, typically takes 6 to 7 hours round trip. The path is well marked, but the final stretch climbs over rock and includes a few short sections fitted with chains, so sturdy footwear and a bit of scrambling confidence help. Is it worth continuing to Lac de Capitello? Many hikers combine both lakes in a single outing. Capitello sits higher up and requires an additional, steeper climb above Melo. The two-lake route is one of the best-known hikes in this part of Corsica, but it takes noticeably longer and more effort than a visit to Melo alone. When is the best time to go? May through October is the safest window, once snow has cleared from the higher ground. Summer days can get crowded — Melo is one of the most visited mountain lakes on the island — so an early start helps avoid the busiest hours on the trail. Frequently asked questions Can you swim in Lac de Melo? The water is glacially cold, fed by snowmelt in a glacier-carved basin, but on warm summer days some hikers do take a quick dip. Is the trail difficult? The path itself is well signposted and doesn't require climbing skills, but the 2023 access change means the walk is now considerably longer than it used to be, and the final chained section demands some care. Can you still drive close to the lake? Not since 2023 — the damaged bridge at Tragone blocks access to the old Grotelle car park, so hikers now park at Frassetta or use the seasonal shuttle bus. How big is the lake? Lac de Melo covers about 6.5 hectares and reaches nearly 20 metres in depth, making it one of the larger natural freshwater lakes on Corsica.

Estany de Lanoset
Angoustrine-Villeneuve-des-Escaldes
Estany de Lanoset is a small high-altitude tarn in the French Pyrénées-Orientales, within the commune of Angoustrine-Villeneuve-des-Escaldes, in the Cerdagne (Cerdanya) region of Northern Catalonia. Also known locally as Lanouzet, it sits in the Carol valley at an elevation of roughly 2,234 metres. How big is the lake, and where exactly is it? Covering an area of around 2 hectares, Estany de Lanoset is a modest, quiet body of water - far smaller than the nearby Lac de Lanoux (Estany de Lanós), the largest lake in the entire Pyrenees. The name "Lanoset" is a Catalan diminutive of "Lanós" (the "-et" suffix meaning "smaller"), which can cause confusion: the two are separate lakes in the same area, not two names for one and the same lake. The tarn lies in the French commune of Angoustrine-Villeneuve-des-Escaldes, at the northern edge of Cerdagne, close to the Carlit massif, an area known for its cluster of glacial lakes. Is there a hiking trail to it? Yes. Estany de Lanoset sits along the GR10, the long-distance trail that crosses the French Pyrenees from coast to coast. The route passes the tarn before climbing to the Portella de la Grava pass (2,426 m) and then descending toward Lac des Bouillouses, one of the most visited destinations in the region. As a result, Lanoset often serves as a waypoint or a short rest stop for hikers covering this stretch of the GR10. What should visitors know before heading up? This is high-mountain terrain, realistically accessible only during the summer months; in spring and autumn the trails in this part of Cerdagne can still hold snow, and the passes call for extra caution. Angoustrine or the area around the Lanoux dam are the usual starting points, and the hike should be treated as a genuine mountain outing that requires fitness and proper footwear. Frequently asked questions Is Estany de Lanoset the same lake as the famous Lac de Lanoux? No. Lac de Lanoux (Estany de Lanós) is a separate, much larger lake, known among other things for a historic France-Spain dispute over shared border waters. Lanoset is a smaller, distinct tarn nearby - the similar name reflects a relationship, not identity. Where exactly is the lake located? In the commune of Angoustrine-Villeneuve-des-Escaldes, in the Pyrénées-Orientales department, at about 2,234 metres of elevation, in the Carol valley. Can you reach the lake on a day hike? Yes, for reasonably fit hikers - it lies directly on the GR10 and can be worked into a day trip from around Angoustrine, though it demands good fitness and attention to high-mountain conditions. What else is worth seeing nearby? The Carlit massif with its many glacial lakes, and Lac des Bouillouses, reached via the next stretch of the GR10 beyond the Portella de la Grava pass.
-
Lac de Capitellu
Corte
Lac de Capitello is a high-altitude lake tucked into the upper Restonica valley in the Haute-Corse region of Corsica, a short but demanding walk above the town of Corte. Sitting at 1,930 meters in a glacial cirque, it is generally regarded as the deepest natural freshwater lake on the island, plunging more than 40 meters below a surface that covers only around 0.055 square kilometers. Ringed by bare granite walls, the lake often stays partly frozen or snow-covered well into early summer. Where is the lake located? Capitello sits above its better-known neighbor, Lac de Melo, and together the two form one of the most popular lake pairings in Corsica. Both lie in the valley carved by the Restonica river, a tributary of the Tavignano, roughly 16 kilometers from Corte — the old Corsican capital and the natural base for exploring this part of the interior. How do you get there? Access is via the Restonica valley road, a narrow, scenic route that ends at the Frassetta parking area, where the walking trail begins. Because parking space is limited and traffic can be heavy in summer, a shuttle bus runs from Corte to Frassetta between early May and the end of September — using it avoids the hassle of hunting for a spot along the roadside. How long does the hike take, and how hard is it? The path is well marked but not casual. Reaching the lower Lac de Melo (1,711 m) and returning typically takes 6 to 7 hours. Pushing on to Capitello adds roughly another hour and a half each way. The final stretch is the toughest part of the route: the ground turns steep and rocky, with chains fixed to the rock in a few sections to help hikers scramble up safely. This is a full day out in the mountains, best suited to hikers who are reasonably fit and wearing proper footwear. Why go beyond Lac de Melo? Many visitors stop at Lac de Melo, which is already a scenic destination on its own. Those who continue on to Capitello are rewarded with a starker, wilder setting: a bare rock basin carved by glaciers, holding water with a striking turquoise tint. The contrast between the still lake and the jagged granite peaks surrounding it is often cited as one of the more dramatic mountain landscapes in Corsica. When is the best time to go? The hiking season for this route runs from May through October. Earlier in the year, snow can still linger around the lake itself, making the chain-assisted sections trickier to cross. Conditions are generally best from June to September, once the snow has fully cleared and the days are long enough to complete the full round trip without rushing. Frequently asked questions Can you drive directly to the lake? No. The road only reaches the Frassetta parking area in the Restonica valley; from there it's a multi-hour walk to reach Capitello. Is the trail suitable for children? The section up to Lac de Melo is manageable for many families, but continuing to Capitello involves steep, chain-assisted sections that call for more strength and caution. Can you swim in the lake? The water stays very cold for most of the year because of the altitude and snowmelt origin, though some visitors do take a brief dip during peak summer. Do you need a guide? The trail is well marked and heavily used, so most hikers manage it on their own — but checking the weather forecast and wearing sturdy footwear is essential given the steep, rocky final approach.

Lac de Nielluccio
Ghisoni
Lac de Nielluccio is a small mountain lake in Corsica, sitting within the commune of Ghisoni in the Haute-Corse department. It lies in the Monte Renoso massif, between the peak itself and the Ventosa ridge, at an elevation of 1,919 metres. The lake is one of five lakes scattered around Monte Renoso within the Fiumorbo watershed, and it draws mainly hikers looking for a quiet, high-altitude corner of the island away from the coastal crowds. Where exactly is the lake? Lac de Nielluccio sits deep in Corsica's interior, in the commune of Ghisoni, on the high ground of the Monte Renoso massif (2,352 m). Its better-known neighbour, Lac de Bastani, lies less than a kilometre away, closer to the summit itself. The two lakes share the same glacial origin and are often visited on the same outing, but they are separate bodies of water with distinct settings — Bastani sits higher and nearer the peak, while Nielluccio lies a little further down, on the valley side. What does the lake look like? The lake is modest in size, covering roughly 1.2 hectares, with a maximum depth of about 15 metres. It occupies a rocky glacial basin typical of Corsica's high interior, ringed by bare granite slopes rather than forest. The water is usually still and dark, standing out against the pale rock around it. Levels can drop noticeably in the warmer months, exposing a stony shoreline. How do you get there? Access is on foot, from trails rising out of the Fiumorbo valley. One common approach starts at the Casaccie bridge and follows a stretch of the GR20 long-distance trail upward, passing the former Traggette sheepfolds before reaching the lake. Another route links up with the nearby Lacs de Rina, returning via the same section of the GR20. Neither route is technically extreme, but both demand a reasonable level of fitness: expect steep, rocky stretches, especially on the final approach to the water. The path is marked with cairns, though in fog or poor visibility it can be difficult to follow, so carrying a map or GPS is a sensible precaution. Who is this hike suited for? This is a destination for prepared hikers rather than casual visitors — there are no lifts, access roads, or facilities anywhere near the lake itself. The payoff is solitude and views over the bare rock of the Renoso massif that are hard to find in Corsica's more accessible spots. Plan for a full day out, wear proper hiking boots, and carry enough water and sun protection, since there is little to no shade once you're above the treeline. Frequently asked questions How high up is Lac de Nielluccio? The lake sits at 1,919 metres above sea level, within the Monte Renoso massif. Is it a large lake? No. It covers about 1.2 hectares and reaches a maximum depth of roughly 15 metres, making it a small, intimate mountain lake. Is Lac de Nielluccio the same as Lac de Bastani? No. They are two separate lakes close to each other in the same massif. Bastani sits higher, nearer the summit of Monte Renoso, while Nielluccio lies somewhat lower, toward the valley. How do you reach the lake? Most visitors walk in from the Casaccie bridge, following part of the GR20 past the former Traggette sheepfolds, or approach via the nearby Lacs de Rina. The hike requires decent fitness and care on the steep, rocky sections. Is the trail well marked? Partly. Cairns guide the way, but in fog or low visibility the route can be hard to follow, particularly on the final, more demanding stretch — a map or GPS device is worth carrying.

Estany de Trebens
Angoustrine-Villeneuve-des-Escaldes
Estany de Trebens is a small glacial lake in the Carlit massif, within the commune of Angoustrine-Villeneuve-des-Escaldes in the Pyrénées-Orientales department, in the historic Cerdagne (Cerdanya) region straddling the Catalan-French border. The Catalan word "estany" simply means "lake," a name shared by dozens of other high-altitude lakes scattered across this mountain range. Where is Estany de Trebens located? The lake sits at an altitude of roughly 2,330 metres and covers an area of just under 4 hectares. It is one of many glacial lakes in the Carlit massif, shaped by glacier activity during the Pleistocene. Its coordinates are 42.576683, 1.960839. Estany de Trebens is fed by water flowing down from the higher-lying Estany de Sobirans, as well as by snowmelt from the Coma de Trebens, a mountain cirque above it. From its shores, hikers get a clear view of Pic Carlit, the massif's highest peak at 2,921 metres and a popular objective in this part of the Pyrenees. How do you get to the lake? The most common starting point for reaching Estany de Trebens is the Bouillouses dam (barrage des Bouillouses), from which a marked trail leads past several other lakes in the massif, including Estany del Viver, Estany Llat, and Estany d'en Gombau. This route forms part of a wider loop known as the "loop of the twelve Carlit lakes," roughly 11 kilometres round trip from the dam. Estany de Trebens lies near the end of this route, just before the final approach to Pic Carlit, which makes it a natural stopping point before a summit attempt — or a turnaround spot for less experienced hikers. A small mountain shelter (abri) stands near the lake, offering protection in case weather conditions change suddenly, which can happen even in summer at this altitude. What should you know before hiking there? Because of the altitude — over 2,300 metres — the trail is realistically only accessible from late spring to early autumn; for much of the year the area remains snow-covered. The terrain around the lake is rocky and open, with no tree cover, typical of the alpine zone of the Eastern Pyrenees. Proper hiking boots, sun protection, and enough water are essential, since there are no supply points along the trail. The Cerdagne region is known for its exceptionally sunny climate and serves as a gateway to numerous hiking routes leading to the lakes of the Carlit massif. Each lake has its own character, ranging from small, shallow pools to larger, deeper basins framed by rocky ridgelines. Frequently asked questions How big is Estany de Trebens? The lake covers about 4 hectares and sits at an altitude of nearly 2,330 metres. Where does the lake's water come from? It is fed by the higher-altitude Estany de Sobirans and by snowmelt from the Coma de Trebens cirque. How do you reach Estany de Trebens on foot? The usual route starts at the Bouillouses dam and passes Estany del Viver, Estany Llat, and Estany d'en Gombau, forming part of the roughly 11-kilometre loop of the twelve Carlit lakes. Is there any shelter near the lake? Yes, a small mountain shelter (abri) stands nearby, useful if the weather turns suddenly. When is the best time to visit? Given the altitude and snow cover for much of the year, June through September is the best window for a visit.

Lac de Ribou
La Tessoualle
Lac de Ribou is an artificial lake about 4 km southeast of Cholet, spanning the boundary of the Cholet, La Tessoualle, Maulévrier and Mazières-en-Mauges municipalities in the Maine-et-Loire department of western France. Formed on the Moine river and the Trézon stream by a dam built in La Tessoualle, it has become one of the main outdoor destinations for the Choletais area. How did the lake come to exist? The lake is not natural — it exists because of the Ribou dam (also known as the Moulin-Ribou dam), built between 1955 and 1957 to secure a drinking-water supply for Cholet. The reservoir basin was filled in 1958. Before that, the town relied on wells between Cholet and Puy-Saint-Bonnet that could no longer keep up with a growing population. The dam itself is 162 metres long and 15 metres high, built as an arch (vault-type) structure. It still serves its original purpose today, supplying drinking water to Cholet as well as to La Tessoualle, Le Puy-Saint-Bonnet and Saint-Christophe-du-Bois. How big is Lac de Ribou? The lake covers roughly 80 hectares and holds an estimated 3.2 million cubic metres of water. It is modest in scale compared with France's large natural lakes, but combined with the surrounding woods and meadows it forms a landscape that has turned into a genuine local attraction rather than just a piece of water infrastructure. What can visitors do at the lake? A year-round leisure complex has grown up around the shoreline. Water-sports fans can try windsurfing, sailing and canoeing, while on dry land there are tennis courts and an archery range. The site draws both Cholet residents looking for an afternoon out and travellers spending a longer stay in the region. Where can you swim? Supervised sandy beaches operate along the shore in summer, with dedicated swimming areas and play zones for children. Dogs are welcome on the site too, which sets Lac de Ribou apart from many other French bathing spots that restrict pets. Is there a trail around the lake? Since February 2020, an 11 km signposted footpath called "La Ribou'cle" has circled the entire lake. Walking the full loop takes about 2 hours and 50 minutes and gives a changing view of the water, from wooded stretches to the top of the dam itself. Where can you stay nearby? A campsite right on the lakeshore, Camping Lac de Ribou, offers tent pitches, mobile homes and gîtes alongside a heated pool complex with water slides. It makes a convenient base for families and for anyone wanting an extended stay by the water without commuting in from central Cholet. Frequently asked questions Is Lac de Ribou a natural lake? No — it is an artificial reservoir created after a dam was built on the Moine river between 1955 and 1957, with the basin filled by 1958. What is the lake actually used for besides tourism? Its primary role is drinking-water supply for Cholet and the neighbouring municipalities of La Tessoualle, Le Puy-Saint-Bonnet and Saint-Christophe-du-Bois. Can you swim in the lake? Yes, supervised beaches with swimming areas and a children's play zone operate during the summer season. How long is the walking trail around the lake? The "La Ribou'cle" loop is 11 km long and takes roughly 2 hours 50 minutes on foot. Is there accommodation close to the lake? Yes, a lakeside campsite offers pitches, mobile homes and gîtes, along with a heated swimming pool and water slides.

Lac de la Remuaz
Chamonix-Mont-Blanc
Lac de la Remuaz is a small mountain lake in the Aiguilles Rouges massif, within the commune of Chamonix-Mont-Blanc in Haute-Savoie, and inside the Aiguilles Rouges Nature Reserve. Sitting at roughly 2,100–2,160 metres, it rests in a grassy hollow at the foot of the Aiguille d'Encrenaz, tucked away from the busy balcony trail that leads to the far more famous Lac Blanc. How do you get to Lac de la Remuaz? The usual starting point is the Col des Montets (1,461 m), a pass on the road linking Argentière and Vallorcine. From there, a well-marked balcony trail climbs across the flank of the Aiguilles Rouges toward Lac Blanc. To reach Lac de la Remuaz, hikers leave this main path and turn onto a faint, unmarked traverse that branches off near 2,030 m, by two distinctive boulders on a second plateau. From that point it's a further short climb to the sloping plateau of La Remuaz, where the lake sits. How long does the hike take, and how hard is it? Counted from Col des Montets, the round trip typically takes around 3.5 hours and involves roughly 700 metres of elevation gain. The route is rated moderate: no climbing equipment is needed, but the unmarked section beyond the main trail is faint underfoot and calls for some route-finding confidence. Why detour off the main trail? Lac Blanc, reached via the same balcony path, is one of the most visited hiking destinations around Chamonix and gets crowded in season. Lac de la Remuaz sits out of sight in its own side hollow, which keeps it markedly quieter — it draws hikers looking for solitude away from what regulars sometimes call the "highway" toward Lac Blanc. Fitter, well-prepared walkers sometimes continue past the lake toward the Col de l'Encrenaz (2,579 m) for a higher traverse of the ridge. What rules apply here? The lake lies inside the Aiguilles Rouges National Nature Reserve, where strict conservation rules apply: picking plants is forbidden, and dogs are not allowed under any circumstances, even on a leash. Anyone planning a visit should factor this in before setting out. Frequently asked questions How high up is Lac de la Remuaz? The lake sits at approximately 2,100–2,160 metres, on a plateau below the Aiguille d'Encrenaz. Where does the hike start? Most hikers begin at Col des Montets (1,461 m), on the road between Argentière and Vallorcine. Is the trail signposted the whole way? The main balcony trail toward Lac Blanc is well marked, but the turn-off to Lac de la Remuaz is a faint path starting near two boulders at about 2,030 m — it requires careful navigation. Can I bring a dog? No. The area lies within the Aiguilles Rouges Nature Reserve, where dogs are banned even on a leash. How long does the full outing take? From Col des Montets, allow about 3.5 hours for roughly 700 metres of elevation gain.

Lac d'Issarlès
Le Lac-d'Issarlès
Lac d'Issarlès is a volcanic lake in the Ardèche department, sitting at 1,000 metres above sea level in the commune of Le Lac-d'Issarlès, within the Auvergne-Rhône-Alpes region. Covering roughly 0.9 km², it ranks among the deepest volcanic lakes in France. How did the lake form? The lake fills a maar crater, produced by violent phreatomagmatic eruptions — explosions triggered when rising magma met underground water, setting off a series of steam-driven blasts. The eruptions took place tens of thousands of years ago, during a period when Neanderthals still inhabited the surrounding area; the ash and steam columns would have been visible from far off. The crater is considered one of the deepest of its kind in France, with the lake bed lying more than 100 metres below the surface. What has the lake been used for? In the 19th century, engineer Louis Eugène Mouline proposed piping water from Issarlès to the city of Lyon through a roughly 150 km aqueduct; the scheme was never built. Since 1954, the lake's water has instead fed the Montpezat hydroelectric plant, part of a cascade system that channels water from this volcanic plateau down toward the Rhône valley. The lake itself has been protected as a natural heritage site since 1935. What can visitors do at the lake? In summer, swimming is the main draw: the water stays clear and cool thanks to underground springs, and supervised beaches — including the Plage de la Pommeraie — operate through July and August. A water-sports base on the shore rents out pedal boats, kayaks and canoes, and conditions are also suitable for sailing. Anglers come for trout, pike and perch in the lake's deep, clear waters. A footpath circles the entire lake, taking around an hour to walk, and the surrounding roads are popular with mountain bikers. How to get there and where to stay? Le Lac-d'Issarlès sits on the high plateau of Ardèche, ringed by volcanic hills known locally as "sucs," a landscape typical of this part of the Massif Central. The village itself is a small lakeside holiday base, with most accommodation clustered around the shore. It makes a convenient starting point for exploring the wider Monts d'Ardèche area, known for its extinct volcanic scenery. Frequently asked questions Can you swim in Lac d'Issarlès? Yes — supervised beaches operate in summer, and the water is kept clear and cool by underground springs. Is the lake a volcanic crater? Yes, it occupies a maar crater formed by a phreatomagmatic eruption tens of thousands of years ago. How deep is the lake? It is one of the deepest volcanic lakes in France, with a depth of more than 100 metres. Does the lake generate electricity? Yes, since 1954 its water has supplied the Montpezat hydroelectric power plant. What activities are available on the shore? Swimming beaches, boat and kayak rentals, fishing, and a walking trail around the entire lake.
