Lac d'Arboréiaz

Saint-Germain-les-Paroisses

Lac d'Arboréiaz is a small lake in the Ain department of eastern France, straddling the boundary between the communes of Saint-Germain-les-Paroisses and Colomieu. Cradled in a hollow shaped by glacial erosion and ringed by reed beds and wet meadows, it has a quietly untamed feel that sets it apart from the region's more developed leisure lakes. Where is the lake and how big is it? Sitting at roughly 340 metres above sea level in the Bugey — the hill country wedged between the Jura range and the Rhône valley — Lac d'Arboréiaz covers about 7 hectares and reaches an average depth of 12 metres, unusually deep for its modest surface area. Its outflow feeds the Agnin stream, itself a tributary of the Gland river, tying the lake into the broader Bugey watershed. What can visitors do here? Fishing The lake is managed by the local municipality primarily as a fishery. Day passes and annual permits are both available, and angling remains the main organised activity on the water — Arboréiaz draws local residents and regional anglers rather than crowds of holidaymakers. Walking A network of footpaths links Arboréiaz to the nearby Lac d'Armaille via the Corne-Bœuf ridge. The loop connecting the two lakes is a well-known option for visitors after a few unhurried hours outdoors, taking in wetland and woodland views typical of the Bugey countryside. Quiet observation Because the shoreline is largely marsh and reed, the lake also appeals to birdwatchers and anyone after stillness rather than activity. There are no beaches or swimming facilities, and the atmosphere leans contemplative rather than sporty. Does the lake have any cultural significance? Yes. Lac d'Arboréiaz served as a filming location for "Les Enfants du marais" ("Children of the Marshland"), Jean Becker's 1999 French film starring Jacques Gamblin, Jacques Villeret, Michel Serrault and André Dussollier. The lake's marshy, timeless setting suited the film's story of rural interwar France. How do you get there? The lake sits right on the boundary between Saint-Germain-les-Paroisses and Colomieu, within easy reach of the larger towns of the Bugey. There is little tourist infrastructure — no large car parks or restaurants — something many visitors see as part of the appeal rather than a shortcoming. FAQ Can you swim in Lac d'Arboréiaz? No developed swimming area exists. The lake is managed chiefly for fishing, and its marshy, reed-lined banks aren't suited to bathing. Do you need a permit to fish? Yes. Fishing is regulated by the municipality, with both daily and annual permits issued locally. How large is the lake? It covers about 7 hectares with an average depth of around 12 metres. Are there hiking trails nearby? Yes, a trail connects Lac d'Arboréiaz to the neighbouring Lac d'Armaille by way of the Corne-Bœuf ridge. Why is the lake known beyond the local area? It featured as a filming location in Jean Becker's 1999 film "Les Enfants du marais," which starred well-known French actors.

Lac Foréant

Abriès-Ristolas

Lac Foréant sits at 2,618 metres above sea level in the commune of Abriès-Ristolas (Hautes-Alpes), within the Queyras Regional Natural Park. The lake occupies the Bouchouse valley, right below the Col Vieux pass and the steep rock faces of La Taillante, and is ringed by high peaks — Pic Foréant (3,081 m), Pain de Sucre (3,208 m) and Taillante itself (3,197 m). How do you get to Lac Foréant? The shortest approach starts at Col Vieux, a roughly 45-minute walk that families often choose because the gradient stays gentle. A second option climbs from Col Agnel and takes about an hour and a half through open, panoramic terrain. Hikers following the GR58 (Tour du Queyras) from L'Échalp reach neighbouring Lac Égorgeou first, then continue upward to Lac Foréant, which lies higher and ranks among the larger lakes in this part of the massif. The same stretch of trail is shared with the GRP Tour du Pain de Sucre. What makes this lake stand out? Lac Foréant is of glacial origin and borders both the Taillante ridge and the Eychassier ridge. With a surface area of around 4.6 hectares, it counts among the largest bodies of water in Queyras, which helps explain its status as one of the more recognisable stops on the Tour du Queyras. Its appearance shifts through the season: as late as the end of June the surface can still carry ice or snow, and it's only the summer warmth that reveals the deep blue water beneath the Taillante cliffs that most photographs show. The Bouchouse valley — more than a viewpoint Lac Foréant shares the Bouchouse valley with two other lakes, Baricle and Égorgeou. This corner of Queyras is notable across the whole Alpine arc for an unusual, well-developed community of marsh plants, protected under both national and European law. Naturalists have recorded around sixteen rare or protected species in the valley, including the alpine ptarmigan, the mountain hare, arctic rush, tussock grasses, Rostan's gentian and several sedge species adapted to these wet, high-altitude patches. Visitors are asked to keep to marked paths for this reason. Who is the hike suited to? Because several approaches exist, the walk to Lac Foréant works both for families after a short, scenic outing from Col Vieux and for more seasoned walkers folding the lake into the multi-day Tour du Queyras. Those circling the massif on foot — starting, for example, from Ceillac — often treat the quiet Bouchouse valley as a place to recover after the tour's first, more demanding stages. FAQ How high up is Lac Foréant? The lake sits at 2,618 metres, in the commune of Abriès-Ristolas in the Hautes-Alpes. How long does it take to reach the lake? The shortest route, from Col Vieux, takes about 45 minutes. From Col Agnel, allow roughly 1.5 hours. Is Lac Foréant the same as Lac Égorgeou? No — they are two separate lakes in the same Bouchouse valley. Lac Foréant lies higher and is larger, and the GR58 passes Lac Égorgeou before reaching Lac Foréant. Can you walk freely around the lake? Given the rare and protected plant and animal species in the area, it's best to stay on the marked paths through the Bouchouse valley. When is the best time to go? Summer, once snow and ice have cleared from the lake's surface — earlier in the season, such as late June, it can still be partly frozen.

Lac de Roue

Arvieux

Lac de Roue is a small lake in the commune of Arvieux, within the Queyras Regional Nature Park in the Hautes-Alpes department of France. Sitting at just under 1,850 metres above sea level, it offers a gentler, more sheltered landscape than the bare rock and scree that dominate much of the surrounding valley. Where is Lac de Roue located? The lake lies within the territory of Arvieux, close to Château-Queyras, one of the area's historic villages. The whole site falls inside the Queyras Regional Nature Park, a protected area covering the upper valley of the Guil river. The lake was formerly known as Marais de la Motte Tremblante, a name pointing to its origin as a wetland that was later turned into open water. What makes the setting distinctive? Unlike most alpine lakes in Queyras, which sit exposed among rock and scree, Lac de Roue is ringed by trees and meadow. It lies inside a larch forest, giving the scenery a softer, almost North American feel rather than a typical high-alpine one. Nearby is Lac Miroir, the other lake in the area bordered by larch trees. Pic de Rochebrune is the only summit visible from the shore, since the surrounding forest screens off the rest of the skyline. In autumn the larches turn gold and orange, and at sunset the light reflects across the water, making the lake a favourite subject for photographers. What can visitors do there? A picnic area with tables and a barbecue spot has been set up in the shade of the trees, making the lake an easy destination for a family outing. Local residents often come here outside the peak tourist season, and long-distance hikers on the GR5 and GR58 trails use it as a stopping point along their route. The paths around the lake also attract mountain bikers in summer and snowshoers in winter. How do you get to Lac de Roue? Two routes lead to the lake. The first starts at Château-Queyras and follows the road toward Souliers before reaching the shore. The second begins at Chalp d'Arvieux and passes through the hamlet of Les Maisons; from there the walk to the lake takes around 50 minutes, covering 2.1 km with about 160 metres of elevation gain, an easy enough route for families with young children. FAQ Is Lac de Roue a natural or an artificial lake? It is an artificial lake, created on the site of a former wetland known as Marais de la Motte Tremblante. How high up is the lake? Lac de Roue sits at just under 1,850 metres above sea level, in the commune of Arvieux within the Queyras Regional Nature Park. Is the walk to the lake suitable for children? Yes. The approach from Les Maisons is short, about 2.1 km with only 160 metres of climbing, making it a manageable family walk. Can you have a picnic at the lake? Yes, there is a dedicated picnic area by the shore with tables and a barbecue spot under the trees. Does the lake lie on any long-distance hiking trails? Yes, it serves as a stop along both the GR5 and GR58 long-distance trails.

Lac de Suyen

Arrens-Marsous

Lac de Suyen is a small mountain lake in the commune of Arrens-Marsous, in the Hautes-Pyrénées department of France, sitting at an altitude of 1,536 metres in the Val d'Azun valley. Covering only about 0.02 square kilometres, it ranks among the smaller lakes of this part of the Pyrenees, its level raised slightly by a small dam. The lake is fed by the Gave d'Arrens, a mountain stream flowing down from the upper valley. Lying inside the Pyrenees National Park, Suyen is the first high-altitude lake reached by hikers approaching from the Val d'Azun side, which makes it a popular target for a half-day outing. How do you get to Lac de Suyen? The usual starting point is the Plan d'Aste car park, at the end of the D105 road that climbs toward Lac du Tech, at roughly 1,470 metres. It sits about 10 kilometres south of the village centre of Arrens-Marsous, and the drive from Argelès-Gazost takes around half an hour. The Maison du Parc des Pyrénées, an information point for the national park, is located close to the car park. The D105 access road is closed during winter and part of spring, so it is worth checking conditions before setting out. What does the trail to the lake look like? From the Plan d'Aste car park, the path leads past the building there and crosses the Gave d'Arrens on a wooden footbridge. From there it winds through an attractive fir forest before opening onto the lakeshore. The route is easy, clearly marked, and gains little elevation, making it suitable for families with children. A round trip typically takes between two and two and a half hours, depending on pace and the number of stops along the way. What else can you see along the way? Along the route, the Doumblas waterfall makes for a worthwhile stop, and a small pool near the path is often a hit with children. More experienced walkers can extend the hike further into the valley toward other lakes, such as Lac de Batcrabère or Lac de Rémoulis, though reaching them requires considerably more time and stamina. Is the lake within a protected area? Yes, part of the route runs through the core zone of the Pyrenees National Park, where dogs are not allowed. This is a strictly protected natural area, so hikers should stay on the marked path and respect the park's rules. FAQ At what altitude is Lac de Suyen? The lake sits at 1,536 metres in the Val d'Azun valley. How big is the lake? It is a very small body of water, covering about 0.02 square kilometres. How long does the hike take? From the Plan d'Aste car park, at 1,470 metres, the round trip usually takes two to two and a half hours. Is the trail suitable for children? Yes, it is an easy, well-marked path with little elevation gain, generally considered family-friendly. Are dogs allowed? Not throughout — part of the trail lies within the national park's core zone, where dogs are prohibited. Is the access road open all year? No, the D105 road to Plan d'Aste is closed in winter and part of spring.

Lac Égorgeou

Abriès-Ristolas

Lac Égorgeou is a high-altitude lake tucked into the Bouchouse valley, within the commune of Abriès-Ristolas and the Queyras Regional Natural Park in the Hautes-Alpes, French Alps. Sitting at the foot of the Taillante ridge, it's one of the classic lake stops on the long-distance GR58 trail circling the Queyras massif, close to the Italian border and the Monviso massif. Where is the lake located? Égorgeou sits at roughly 2,394–2,400 metres above sea level, on land that once belonged to the village of Ristolas before it merged with Abriès. It shares the upper valley with the smaller Lac Baricle, a well-known fishing lake right next door, and the two are usually visited together on the same outing. The setting is glacial in character: bare rock, moraine debris, and open alpine pasture above the treeline. How do you get there? Most visitors start from the hamlet of l'Échalp, reached by driving through Aiguilles, Abriès and Ristolas along the D947, with parking available near the Guil river. From there, the walk to the lake takes around two and a half hours and gains close to 700 metres in elevation. The path climbs through forest before opening onto the scenic Chalets de la Médille and Peyroun, landmarks that mark the transition from woodland to bare high-mountain terrain. The route follows the GR58 (Tour du Queyras) and the GRP Tour du Pain de Sucre, both well-marked and hard to lose even for less experienced hikers. What is there to see and do around the lake? Beyond the two lakes, the valley opens views toward the Pain de Sucre and Col Vieux peaks. Hikers who want to extend the walk can continue toward Lac Foréant, about 210 metres higher and roughly 9.5 km further along a route that also loses close to 940 metres elsewhere on the loop, a full day's outing of around four hours one-way. The Bouchouse valley is also ecologically sensitive: it holds relic marsh vegetation dating back to the last glaciation and is protected under a biotope conservation order, with roped-off sections marking areas hikers should not enter. Is it accessible outside summer? Yes — the trail up to Égorgeou can also be done on snowshoes or ski touring gear in winter. The stretch between the Médille chalets and the lake crosses avalanche-prone gullies, so a winter visit calls for checking snow conditions beforehand and going properly equipped. Who is this hike suited for? The route demands stamina rather than technical skill: no climbing gear is needed, but the elevation gain and multi-hour walking time mean it suits hikers already used to full-day mountain outings. It appeals equally to day-trippers based in the Queyras valleys and to long-distance walkers tackling the GR58 in stages. FAQ How high up is Lac Égorgeou? The lake sits at approximately 2,394 to 2,400 metres above sea level, in the Bouchouse valley. Where does the hike start? Almost everyone starts from l'Échalp, near Abriès-Ristolas, reached via the D947 through Aiguilles, Abriès and Ristolas. How long does the walk take? Roughly two and a half hours up from l'Échalp, covering about 700 metres of elevation gain. Are there other lakes nearby? Yes — Lac Baricle sits right next to Égorgeou, and Lac Foréant lies further along the trail, about 210 metres higher. Can you hike there in winter? Yes, on snowshoes or ski touring equipment, though the section near Médille crosses avalanche terrain and needs care.

Lac de la Sagne

Allemond

Lac de la Sagne is a mountain lake in the commune of Allemond, in the Isère department of the Auvergne-Rhône-Alpes region of France. Sitting at roughly 2,065 metres above sea level, it belongs to the Belledonne massif, in the group of high-altitude lakes known as the Sept Laux — a name meaning "seven lakes" even though the group actually counts ten, including Lac de la Corne, Lac Agnelin, Lac Blanc, Lac Noir and Lac Carré. Lac de la Sagne is typically the first lake reached on the classic approach from the Eau d'Olle valley, and its bare, rocky basin framed by Belledonne peaks draws hikers throughout the warmer months. How do you get there? The usual starting point is Le Rivier d'Allemond, a hamlet within the commune of Allemond. From there a road continues roughly 2 km further up the valley to the trailhead, where the path branches off toward the Sept Laux basin and climbs in tight switchbacks. The round trip generally runs 9–10 km with close to 900 metres of elevation gain, making it a full but achievable day hike for anyone in reasonable shape. The final stretch crosses loose, rocky ground and gets noticeably steeper, so sturdy boots and trekking poles are worth bringing. When is the best time to hike? The hiking season around the Sept Laux runs broadly from April to October. Outside that window, the higher sections of the trail can still be covered in snow or ice, and reaching the lake may require winter gear and experience. Conditions are most reliable in summer, once snow has cleared from the upper valley and the approach trail is fully walkable. What wildlife can you expect along the way? The Eau d'Olle valley and the Sept Laux area are known for their alpine wildlife. Chamois are a regular sight, and ibex — reintroduced to the area in the 1980s by hunters and EDF around the time the nearby Grand'Maison dam was built — can also be spotted on the open, rocky slopes surrounding the lakes. Early morning is generally the best time to catch sight of them, when the trail is quiet. What's the wider setting? Allemond stretches across the upper Eau d'Olle valley, between the Belledonne massif and the Grandes Rousses range, close to the well-known Vaujany and Alpe d'Huez ski resorts. While Lac de la Sagne itself sits on the Belledonne side of the valley, the surrounding area combines genuinely wild, high-altitude terrain with easy access to major mountain resorts — a combination that makes it a convenient base for hikers looking to pair a quiet lake outing with the amenities of a larger ski town. Frequently asked questions Where exactly is Lac de la Sagne? In the commune of Allemond, Isère department, within the Belledonne massif, as part of the Sept Laux group of lakes, at an altitude of around 2,065 metres. Where does the hike start? Most hikers begin at Le Rivier d'Allemond, from where a marked trail leads up into the Sept Laux basin. How long is the hike to the lake? The round trip is usually around 9–10 km with roughly 900 metres of elevation gain — a full day out for hikers with a reasonable level of fitness. Is the trail difficult? Yes, it's generally rated as demanding. The final approach runs over rocky, occasionally steep ground, so it's worth allowing plenty of time and packing proper footwear. What's the best season to visit? Broadly April through October, though the trail's upper sections are usually only fully clear of snow during the summer months. Is wildlife visible around the lake? Yes — chamois are common, and ibex reintroduced in the 1980s can also be seen in the surrounding Eau d'Olle valley. Is Lac de la Sagne the only lake in the area? No. It belongs to the Sept Laux group, which actually comprises ten lakes, including Lac de la Corne, Lac Agnelin, Lac Blanc and Lac Noir, so several can often be combined into a single hike.

Lac de la Ponsonnière

Le Monêtier-les-Bains

Lac de la Ponsonnière is a mountain lake sitting at 2,565 m altitude in the Cerces-Thabor massif, within the commune of Le Monêtier-les-Bains in the Hautes-Alpes — on the French side of the Serre Chevalier valley. It's a popular day-hike destination, usually combined with the nearby Grand Lac and the Col de la Ponsonnière (2,613 m) just above it. Where exactly is the lake? Lac de la Ponsonnière lies in a side valley above Le Monêtier-les-Bains, in the Cerces-Thabor range that borders the Écrins massif — whose peaks are visible on the horizon from this area. The lake sits just below the pass of the same name, on the route running from Pont de l'Alpe toward the Savoie border. How do you get to the lake? The trailhead is the car park at Pont de l'Alpe (around 1,710 m), on the road toward Col du Lautaret. From there the path climbs past L'Alpe du Lauzet (1,840 m) and the area around Refuge du Clôt des Vaches, passing Grand Lac on the way before reaching Lac de la Ponsonnière and, further on, the pass itself. The full loop covers roughly 12 km with about 950 m of elevation gain. Plan on around 5 hours total — roughly 3 hours up and 2 hours down. How difficult is the trail? The stretch to the lake itself is easy and clearly marked, manageable even for children used to mountain walking. The short section just below the pass is trickier — a slightly exposed passage that calls for more care, though it isn't technical climbing. The route is often recommended as an easier alternative to the demanding Grand Galibier approach, and it bypasses the toughest section of the classic Grand Lac trail. The best window for this hike runs from July to October, once the trail is clear of snow. What's the scenery like along the way? Highlights include Grand Lac seen en route, the ridgeline of the Arêtes de la Bruyère, and — from the pass itself — a panorama opening toward Savoie. From the slopes above the lake, the Écrins massif is visible in the distance. The hillside the trail follows faces south, which means the snow tends to clear earlier here in spring and summer. Who is this hike suited for? This is a route for hikers with some experience of longer mountain ascents. The section up to the lake alone, without continuing to the pass, is gentler and works well for families with children already used to hiking in the mountains. FAQ How high is Lac de la Ponsonnière? The lake sits at 2,565 m altitude, with the neighboring Col de la Ponsonnière at 2,613 m. Which mountain range is the lake in? It's in the Cerces-Thabor massif, in a side valley above Le Monêtier-les-Bains, in the Serre Chevalier area. Where does the trail start? At the car park by Pont de l'Alpe, around 1,710 m, on the road up to Col du Lautaret. How long does the hike take? The full loop over the pass takes about 5 hours, covering roughly 12 km and 950 m of elevation gain. Is the trail suitable for children? The section up to the lake is easy and fine for children already accustomed to mountain hiking. The climb to the pass includes a short, slightly exposed passage that needs extra care. When is the best time to go? Between July and October, once the trail has cleared of snow and no winter gear is needed.

Lac du Laitelet

Saint-Sorlin-d'Arves

Lac du Laitelet is a small mountain lake sitting at 2,035 metres above sea level in the commune of Saint-Sorlin-d'Arves, in the Maurienne valley of Savoie. It lies right beside the road leading up to the Col de la Croix de Fer, next to two other small lakes, Lac Guichard and Lac Potron. Together the three form a well-known loop walk, with views opening onto the jagged Aiguilles d'Arves. Where exactly is the lake? Lac du Laitelet sits on the Savoie side of the Arves massif, close to the Col de la Croix de Fer, one of the best-known mountain passes in the Grandes Rousses area. Only a short stretch separates the lake from the road, which makes it one of the easiest high-altitude lakes to reach around Saint-Sorlin-d'Arves. How do you get there? Access is via the road climbing toward the Col de la Croix de Fer — the lake sits directly alongside this route, so the walk in from the roadside parking is short and largely flat. That is why the spot draws not just hikers but also families with young children and visitors with limited mobility. The lake can technically be reached year-round, though in practice this depends on snow cover and whether the pass road has been cleared; in winter and early spring the area is often still under snow. What can you do at Lac du Laitelet? The lake is a place to slow down among high peaks — visitors picnic on the shore, watch the Aiguilles d'Arves reflected in the still water, and pick wild bilberries growing nearby in season. Anglers fish directly from the bank. It also works well as a starting point for a longer walk: the loop linking Lac du Laitelet with Lac Guichard and Lac Potron typically takes around an hour over flat, scenic ground. What views does the lake offer? The main draw is the view of the Aiguilles d'Arves, three sharp rock peaks of the massif, the tallest rising above 3,500 metres. Their outline reflects in the calm surface of the lake, especially on still mornings, making the spot a popular viewpoint and an easy short walk from Saint-Sorlin-d'Arves. Who is this spot suited to? Thanks to its easy access right off the road, Lac du Laitelet works as a family outing, a stop on the drive over the Col de la Croix de Fer, or a launch point for a longer walk around the nearby lakes. There is no steep approach here, just the kind of high-altitude Savoie scenery that draws people up to this pass in the first place. FAQ How high up is Lac du Laitelet? The lake sits at 2,035 metres above sea level. Which commune is the lake in? Lac du Laitelet belongs to Saint-Sorlin-d'Arves, in the Maurienne valley in Savoie. Is the walk to the lake difficult? No — the lake lies right next to the road up to the Col de la Croix de Fer, so reaching it doesn't require a long or steep climb. What other lakes are nearby? Lac Guichard and Lac Potron sit close by, and together with Lac du Laitelet they form a well-known three-lake loop walk. What can you see from the lake? The shore offers views of the Aiguilles d'Arves, the three-peaked rock massif that defines this part of the Maurienne valley. Is the lake accessible all year? Yes, depending on snow conditions — access depends on whether the pass road has been cleared.

Lac d'Anterne

Passy

Lac d'Anterne is a high-altitude lake sitting above 2,000 metres in the commune of Passy, in the Haute-Savoie department of the French Alps. It lies inside the Sixt-Passy nature reserve, close to the village of Sixt-Fer-à-Cheval, right below the rocky wall of the Rochers des Fiz. Where exactly is the lake? The lake occupies a small high-mountain plateau ringed by the steep cliffs of the Rochers des Fiz, at coordinates roughly 45.99°N, 6.80°E. Although it falls administratively within Passy, most hikers approach from Sixt-Fer-à-Cheval or the Giffre valley. The surrounding terrain belongs to the Sixt-Passy nature reserve, one of the larger protected alpine areas in France. How high up is it? Lac d'Anterne sits at roughly 2,061 metres. A short climb further up leads to the Col d'Anterne, at about 2,257 metres, which is the real reward for many hikers: from the pass, a wide panorama opens onto the Mont Blanc massif, the Aiguille Verte and Les Drus - some of the best-known summits of the French Alps. What does the trail to the lake look like? The approach usually begins with a gentle climb through shaded forest before passing two waterfalls, the Sauffaz and the Pleureuse. From there the path steepens toward the Collet d'Anterne, with the views opening up gradually along the way. Near the lake stands the Refuge d'Anterne, also known as the Refuge Alfred Wills, together with the Chalets d'Anterne, a cluster of old mountain shepherd huts. The refuge offers overnight beds and looks straight out at the Rochers des Fiz. A full loop through the area covers well over ten kilometres, which is why the hike is usually rated as demanding rather than easy. What else is worth noticing along the way? Beyond the lake and waterfalls, the trail crosses landscape typical of the Sixt-Passy reserve - alpine pastures, rocky ridgelines and high-altitude plant communities. Chamois and marmots live here, and in summer the pastures are often grazed by sheep. The reserve is one of the largest protected areas in the French Alps, taking in part of the Fiz massif as well as the country around Sixt-Fer-à-Cheval. When is the best time to go? The hiking season here generally runs from June or July through September; earlier in the year, the higher sections of the trail can still be under snow. The clearest views, especially of Mont Blanc from the Col d'Anterne, tend to come in the morning, before the afternoon cloud that regularly builds up over the peaks. Frequently asked questions How high is Lac d'Anterne? The lake sits at an altitude of about 2,061 metres. Can you see Mont Blanc from the lake? The view from the lakeshore itself is limited, but a short walk up to the nearby Col d'Anterne (about 2,257 m) reveals the Mont Blanc massif, the Aiguille Verte and Les Drus. Where's the best place to start the hike? Most hikers set off from around Sixt-Fer-à-Cheval or the Giffre valley, with the trail passing the Sauffaz and Pleureuse waterfalls on the way. Is there anywhere to stay overnight near the lake? Yes, the Refuge d'Anterne (Alfred Wills), next to the Chalets d'Anterne, offers overnight accommodation for hikers. Is the area protected? Yes, the lake lies within the Sixt-Passy nature reserve, one of the larger alpine nature reserves in France.

Lac des salettes

Mormoiron

Lac des Salettes is a man-made lake in the commune of Mormoiron, at the foot of Mont Ventoux in the Vaucluse department of Provence. Built in the 1980s, it is one of the few spots in the region where visitors can swim for free in summer, surrounded by a sandy beach and a pine forest. Is Lac des Salettes a natural lake? No — it was created by human hands. In 1984, the municipality of Mormoiron decided to transform this stretch of land, previously covered by forest on the edge of the village. Workers built a dam and excavated roughly 30,000 cubic meters of earth and sediment, carving out the basin that would become the lake. It officially opened to the public in 1988 and has since grown into one of the most popular outdoor spots around Mont Ventoux. How big is the lake and what surrounds it? The water itself covers about 2 hectares, while the wider site — including the beach and surrounding green space — spans roughly 5 hectares. Taken together with the neighboring vallat de Marqueton ravine, the whole area reaches nearly 29 hectares, which was granted Environmentally Sensitive Area (Espace Naturel Sensible) status in 2019. Pines and willows line the shore, offering shade during the hot Provençal summer, and the beach itself is sandy underfoot. Can you swim there? Yes, and swimming is the main reason people come. In July and August, lifeguards supervise the beach from noon to 7pm. It is one of the rare inland spots in Vaucluse offering free, supervised swimming, drawing around 25,000 visitors over the summer season. What else is there to do besides swimming? The area around the lake offers more than a beach day. Hiking trails, an orienteering course, and mountain-biking paths all start from here, and a treetop adventure park called Ventoux Aventure sits tucked among the trees nearby. One distinctive feature of the surroundings is the colored sand — white, yellow, orange, and red in varying shades — visible along paths that wind through the nearby hills, where the landscape mixes vineyards from the Ventoux appellation with olive and cherry orchards. How do you get there, and what should you know before visiting? Entry to the lake itself is free, but parking is paid: 5 euros for 10 hours, or 35 euros for a longer stay. Restrooms are available near the trailhead. Because Mont Ventoux — nicknamed the Giant of Provence — looms so close, its silhouette stays in view for almost the entire time spent at the water's edge. FAQ Is Lac des Salettes a natural lake? No, it is an artificial reservoir built between 1984 and 1988 after the municipality of Mormoiron constructed a dam and reshaped the site. Is swimming safe there? In July and August, lifeguards watch over the beach from noon to 7pm, making it one of the few supervised inland swimming spots in Vaucluse. Do you have to pay to get in? Access to the lake is free; only parking is paid (5 euros for 10 hours, or 35 euros for longer stays). What can you do besides swim? Hiking, mountain biking, orienteering, and the Ventoux Aventure treetop adventure course, plus nearby trails through colorful ochre-tinted sands. How close is it to Mont Ventoux? Lac des Salettes sits right at the foot of Mont Ventoux, within the commune of Mormoiron, so the mountain stays visible from nearly anywhere along the shore.

Lac du Trou de l'Aigle

Lac du Trou de l'Aigle is a small high-mountain lake in the commune of Allos, in the Alpes-de-Haute-Provence department, right at the heart of the Mercantour massif. Sitting somewhere between 2,600 and 2,700 metres above sea level, at the foot of the peak that shares its name (2,961 m), it counts among the quieter, less-visited hiking destinations in this part of the French Southern Alps. Where exactly is the lake? Lac du Trou de l'Aigle lies within Mercantour National Park, a few hours' walk from the much better-known Lac d'Allos - one of the largest natural lakes in Europe at this altitude. The two lakes are sometimes combined into a single itinerary, but Trou de l'Aigle sits higher and further into the massif, surrounded by rocky ridges and scree, away from the busier paths leading to Lac d'Allos. How do you get there? Several approaches lead to the lake. One common starting point is the Col de la Cayolle, a pass at 2,326 m, from which the trail climbs toward the higher reaches of the massif. Other options run via the Pas de la Grande Barre or the Pas du Lausson. The final stretch of every route crosses broad scree fields and calls for sure footing - some sections are graded for scrambling or light alpinism (PD) rather than plain hiking. A more ambitious version of the outing links the lake with an ascent of Mont Pelat (3,051 m), the highest summit in this part of the Mercantour, before descending toward the refuge above Lac d'Allos. What is there to see along the way? The surrounding terrain is classic high-alpine scenery - bare ridgelines, wide scree slopes, and open views across the neighbouring peaks. Marmots and chamois, the two animals most associated with the Mercantour, are commonly spotted in the higher sections. Some multi-day variants of the route also swing past Le Cimet, an area known for its numerous waterfalls fed by meltwater from higher up the massif. When is the best time to go? Because of the altitude, the hiking season here is shorter than in the valleys below - snow can linger on the passes and scree slopes well into late spring. Summer and early autumn are the most reliable windows, when the trails are clear of snow and the rocky sections are at their safest. FAQ Where is Lac du Trou de l'Aigle located? In the commune of Allos, Alpes-de-Haute-Provence department, within Mercantour National Park, close to Lac d'Allos. How high up is the lake? Roughly between 2,600 and 2,700 metres above sea level, at the foot of the Trou de l'Aigle summit (2,961 m). Is the hike to the lake difficult? Yes - the final stretches cross scree fields and require sure footing, and some route variants involve light scrambling or alpinism-grade terrain. Can the lake be combined with another hike? Yes, popular options link it with an ascent of Mont Pelat or with the route to Lac d'Allos and its refuge.

Lac du Lauzanier

Val-d'Oronaye

Lac du Lauzanier is a high-altitude lake sitting at roughly 2,284 metres above sea level, within the commune of Val-d'Oronaye in the Alpes-de-Haute-Provence department of south-eastern France. It lies in the upper Ubaye valley, right against the Italian border, inside the boundaries of Mercantour National Park. The setting combines wide-open, gently sloping pastureland with classic high-mountain scenery, which is part of why this particular lake has become a favourite for visitors who want a rewarding alpine view without a technical climb. Where exactly is the lake? The lake sits in Val-d'Oronaye, close to the village of Larche and the Col de Larche, the mountain pass that connects this side of the Alps to Italy. Because of that, the whole area has a distinctly cross-border feel: several trails in this part of Mercantour link up with the neighbouring Alpi Marittime park on the Italian side. The valley itself belongs to the wider Ubaye valley system, one of the quieter corners of the French Southern Alps compared to better-known resorts further north. How do you get there? Most visitors start from the Pont Rouge car park, a short distance below the lake. Access is by a narrow departmental road running towards Larche and on to Val-d'Oronaye, as far as the point where private vehicles are allowed. During the summer season a shuttle bus service is often put in place along this stretch, reducing private car traffic deeper into the valley and taking hikers close to the trailhead — a common arrangement in sensitive alpine valleys under park protection. From the car park, the path climbs gradually alongside a small mountain stream, crossing a broad, open valley where sheep graze in the summer months. The route follows waymarked long-distance paths, meaning it forms part of longer treks crossing this section of Mercantour. The stretch leading to the lake itself is considered relatively easy, which makes it accessible even to less experienced walkers and to families with children — one of the main reasons the lake draws steady summer foot traffic. What is there to see around the lake? The surroundings are textbook high-alpine terrain: open meadows, rocky slopes and the ridgelines enclosing the valley. Further up the trail, additional small lakes can be reached, giving hikers a natural way to extend the outing beyond Lac du Lauzanier itself. The whole area falls within Mercantour National Park, so the usual park rules apply: no camping outside designated zones, respect for grazing livestock, and care for the wildlife and plant life that make this stretch of the Alps worth protecting. Who is this hike suited for? Given the gentle gradient and the fairly short distance from the Pont Rouge car park, the walk to Lac du Lauzanier is often recommended as one of the more approachable outings in this part of Mercantour. No advanced mountaineering experience is required, though as with any walk above 2,000 metres, sturdy footwear, a windproof layer and enough water are worth packing — weather in the Ubaye valley can change quickly, particularly in the afternoon. FAQ How high up is Lac du Lauzanier? The lake lies at an altitude of around 2,284 metres. How do I reach the lake? The usual approach is to drive to the Pont Rouge car park near Larche and Val-d'Oronaye, then continue on foot along the marked trail. A shuttle bus often operates along part of the route in summer. Is the trail suitable for families? Yes. The section from the Pont Rouge car park to the lake is gentle and popular with families and less experienced hikers. Are there other natural sights nearby? Yes, further up the valley there are additional lakes and trails continuing deeper into Mercantour National Park, towards the Italian border. Is the lake inside a national park? Yes, Lac du Lauzanier lies within Mercantour National Park, so standard nature-protection rules apply.

Lac Sainte-Anne

Ceillac

Lac Sainte-Anne is the largest lake in the Queyras Regional Natural Park, set within the commune of Ceillac in the French Hautes-Alpes. Covering roughly 8.5 hectares, it sits at 2,414 metres above sea level at the foot of the Pic Nord de la Font Sancte, rising above the valley's other two lakes, Lac Miroir and Lac des Rouites. Its deep turquoise water and the raw high-mountain scenery of the Font Sancte massif make it one of the signature spots of the Queyras. How did this lake form? Lac Sainte-Anne occupies a basin carved by a former glacier, ringed by moraine and bare rock ridges. That glacial origin explains both the striking colour of the water and the stark surroundings: sparse vegetation, scree slopes, and peaks nearby that climb past 3,000 metres. Snow can linger around the basin well into summer, reinforcing the sense of being deep in high-altitude terrain despite the relatively accessible trailheads below. A chapel and a centuries-old pilgrimage A small chapel dedicated to Saint Anne stands on the moraine above the shoreline. The site carries real spiritual weight for the valley's inhabitants: every year on 26 July, a pilgrimage that dates back to the 17th century is held here. Local tradition ties its origin to a legend about two young shepherds who were miraculously saved, an event credited to the saint's intercession. The pilgrimage remains an active part of the Ceillac community calendar to this day. How do you get there? Two main approaches lead to the lake. The shorter one starts from the Chaurionde car park (around 1,967 m); from there it's about 3.2 km and 447 m of ascent to the shore. The longer, more scenic route begins at the Ceillac ski-station car park (around 1,697 m) and passes Lac Miroir on the way, adding up to roughly 5.25 km and 717 m of climbing. Both are genuine high-mountain hikes, so weather and season matter — snow can cover the approach for much of the year, and conditions should be checked before setting out. Beyond the lake: toward Col Girardin Hikers looking to extend the day can continue past Lac Sainte-Anne toward the Col Girardin, which opens onto the descent into the Ubaye valley. This makes the lake a natural staging point rather than a strict end goal, especially for those planning a longer traverse around the Font Sancte massif. FAQ How high up is Lac Sainte-Anne? It sits at 2,414 metres, making it the highest of the main lakes in the Ceillac valley. Is it really the biggest lake in the Queyras? Yes — at around 8.5 hectares, it's considered the largest body of water within the Queyras Regional Natural Park. Where does the name come from? It comes from the chapel dedicated to Saint Anne built on the moraine above the shore, the focus of an annual pilgrimage held every 26 July since the 17th century. Which route is quicker if time is tight? The Chaurionde car park gives the shortest approach; the route via Lac Miroir from Ceillac is longer but shows more scenery along the way. Can the hike be extended further? Yes, the trail continues past the lake toward the Col Girardin and down into the Ubaye valley, allowing for a longer multi-stage route.

Lac des Rouites

Ceillac

Lac des Rouites is a small mountain lake in the commune of Ceillac, within the Parc Naturel Régional du Queyras in the Hautes-Alpes department of France. Sitting at roughly 2,400 meters above sea level, it rests below the Crête des Veyres ridge in a rugged, mineral landscape of scree, glacial moraine, and limestone outcrops — considerably quieter than the better-known lakes nearby. Where is the lake located? The lake lies in the upper Mélezet valley, above the stream's left bank, about 10 kilometers south of central Ceillac. Its coordinates are approximately 44.627 N, 6.785 E. Lac Miroir, a neighboring lake at around 2,215 meters, sits some 180 meters lower — Rouites occupies a higher, wilder pocket of the same valley system. What does the setting look like? Ruins of old alpine shepherd huts stand near the shore, remnants of pastoral use of these high meadows. Surrounding peaks include Pointe de la Saume (3,043 m), Col de la Collette Verte (2,942 m), and Pic des Heuvières. The outflow from the lake eventually feeds the Cascade de la Pisse waterfall further downhill. From the water's edge, hikers get open views over the Ceillac valley and toward Col Girardin. How do you reach Lac des Rouites? Most hikers start from the upper lift station near Lac Sainte-Anne, following yellow PR waymarks and cairns across scree slopes and grassy patches; this approach takes about an hour. The path is faint in places, but markers appear roughly every 10 meters, which keeps navigation manageable. A second option climbs up via Lac Miroir, though this route is steeper and less recommended. Starting instead from the Pied du Mélezet parking area (1,692 m), the full ascent to the lake takes about 2 hours and 15 minutes at a normal pace. Is the hike difficult? The overall grading is moderate, with the scree section above Lac Sainte-Anne being the most demanding stretch. The lower valley trail up to the first lakes is considered fairly easy, but the final leg to Rouites sees far less foot traffic than the paths to Lac Sainte-Anne or Lac Miroir, and can feel more remote as a result. Can it be combined with other lakes? Yes — Lac des Rouites is the third stop on the classic "three lakes of Ceillac" circuit, which also takes in Lac Sainte-Anne and Lac Miroir. The full loop covers about 13 kilometers with roughly 850 meters of elevation gain, making it a full-day outing for hikers in good condition. FAQ How high up is Lac des Rouites? Sources place it between 2,383 and 2,413 meters, so figure on roughly 2,400 meters above sea level. Is the lake hard to find? It's the least visited of Ceillac's three main lakes, and the trail can be indistinct — though frequent yellow waymarks make it manageable for prepared hikers. How long does the hike take? About one hour from the Lac Sainte-Anne area, or roughly 2 hours 15 minutes starting from the Pied du Mélezet parking lot. Which map should I bring? The IGN Top 25 sheet 3537ET covers this part of the Queyras. Is it worth pairing with a longer hike? Yes — many hikers combine it with Lac Sainte-Anne and Lac Miroir on a roughly 13-kilometer loop.

Lac Miroir

Ceillac

Lac Miroir is a small mountain lake in the commune of Ceillac, in the Hautes-Alpes department, set within the Parc Naturel Régional du Queyras. Sitting in a glacially carved basin at roughly 2,214 metres, the lake is ringed by larch trees and takes its name from the still, mirror-like surface that reflects the ridgeline of the Font Sancte massif, the highest summit in the Queyras park, on calm days. Where is Lac Miroir located? The lake lies in a valley above the village of Ceillac, in one of the most mountainous corners of the southern French Alps. Larches cover the surrounding slopes, and the open view toward the jagged crest of Font Sancte makes the spot a favourite stop for photographers and hikers drawn to alpine scenery. How do you reach the lake? The usual approach starts from the Pied du Mélezet car park just outside Ceillac. The path crosses a bridge over the Mélézet torrent, follows the edge of the forest along the stream, then turns off toward the lake and climbs through the woods to reach the water. The ascent typically takes just under two hours, gaining around 500 metres in elevation. This stretch forms part of the GR5, the long-distance trail that crosses the entire Alpine range; beyond Lac Miroir it continues toward Lac Sainte-Anne and the Col Girardin, opening the way to the Ubaye valley. What else is there to know nearby? Further up the valley from Lac Miroir sits Lac Sainte-Anne, a moraine-dammed glacial lake at the foot of Font Sancte (3,385 m). Reaching it from Lac Miroir adds roughly another hour of walking and about 200 metres of additional climbing, and many hikers combine both lakes into a single full-day outing. Lac Miroir is also a fished lake: rainbow trout live in its waters, making it a destination for anglers visiting the Queyras during the summer season. When is the best time to visit? The lake is mainly accessible from late spring through early autumn, once the trail has cleared of snow. In winter the area is used for snowshoe outings, though this requires proper preparation and awareness of avalanche conditions, which are common in the high valleys of the Queyras. Frequently asked questions Is the hike to Lac Miroir difficult? The route is considered fairly moderate by alpine standards — a walk of under two hours with roughly 500 metres of ascent, manageable for hikers with average fitness. Where does the lake's name come from? The name refers to the mirror-like reflection of the surrounding peaks, particularly the Font Sancte massif, visible on the water's surface on still days. Can you swim in Lac Miroir? The lake sits high in the mountains and holds cold, glacially fed water, making it a spot better suited to admiring the scenery and fishing than to swimming. Can the hike continue past Lac Miroir? Yes — the trail running along the lake is part of the GR5 and continues on to Lac Sainte-Anne and the Col Girardin, from where hikers can carry on toward the Ubaye valley. Are there fish in the lake? Yes, Lac Miroir holds rainbow trout, and fishing is practiced there during the season.

Lac des Neuf Couleurs

Saint-Paul-sur-Ubaye

Lac des Neuf Couleurs is a high-altitude lake in the commune of Saint-Paul-sur-Ubaye, in the Ubaye valley (Alpes-de-Haute-Provence), sitting at roughly 2,841 m above sea level in the Chambeyron massif, right on the edge of the Mercantour and the Maritime Alps. It's the kind of destination hikers in this corner of Provence build a whole day around — a stark, rocky basin where the water's shifting colour outshines plenty of better-known alpine lakes. Where does the hike start? The classic starting point is the hamlet of Fouillouse, a scenic spot roughly 30 km from Barcelonnette at the end of the valley road. From there the trail climbs a sun-exposed slope, passes the Refuge du Chambeyron — a mountain hut where hikers can rest or restock — and continues by further lakes, including Lac Long, before reaching the destination. The full loop covers about 16–17 km and takes an average walker 5 to 6.5 hours, with roughly 990 m of elevation gain. It's a demanding day out more because of distance and altitude than technical difficulty. What is there to see at the lake? The lake earns its name from the play of light on its surface: depending on the hour and the weather, the water shifts from turquoise blue to deep emerald green, a striking contrast against the barren, rocky slopes around it. The basin is ringed by peaks above 3,000 m — the Aiguille de Chambeyron (3,412 m), the highest summit in the Alpes-de-Haute-Provence, along with the Brec de l'Homme (3,211 m), the Tête de la Fréma (3,151 m) and the Pointe des Cirques. The water holds several salmonid species, including brown trout and Arctic char. Just above the neighbouring Lac Long sits a visible rock glacier, and rockfall is a regular occurrence in the area — this is landscape still very much in motion. Is there any history to find here? Yes. Fouillouse itself still holds remnants of 1930s military structures built as part of the Maginot Line, including the Fort de Plate Lombarde, a reminder that the Ubaye valley sat on a sensitive border for decades. There's also a small dispute among locals over where the lake's name actually comes from: some mountain guides trace it to nine avalanche corridors feeding the basin, while others in the valley insist it originally referred to nine water flows. No version is settled — which makes it a fun question to ask a local guide on the way up. When is the best time to go? Because of the altitude and exposure, snow can linger on the trail into June, and early in the season hikers should expect snow patches below the Pas de la Couletta (2,752 m) and stay alert to avalanche risk. The safest window is mid-summer through early autumn — July, August and the start of September — when the route is fully clear and daylight hours are longest. Frequently Asked Questions How high is Lac des Neuf Couleurs? The lake sits at roughly 2,841 m above sea level, in the Chambeyron massif. Where's the best place to start the hike? Most hikers begin at the hamlet of Fouillouse in Saint-Paul-sur-Ubaye, following a loop of about 16–17 km. How long does the full route take? Plan for 5 to 6.5 hours of walking and about 990 m of elevation gain — a demanding but technically straightforward day hike. Is there somewhere to stay overnight along the way? Yes, the Refuge du Chambeyron sits along the route and offers a place to rest or resupply.

Lac des Bèches

Saint-Christophe-en-Oisans

Lac des Bèches is a small glacial lake sitting at roughly 2,400 m of altitude in the commune of Saint-Christophe-en-Oisans, deep in the Écrins massif (Isère, Auvergne-Rhône-Alpes). Tucked into the Vallon de la Lavey, it lies within the core zone of the Écrins National Park and ranks among the more demanding but rewarding hiking destinations of the Oisans region. Where exactly is the lake? The lake sits in high alpine terrain of rock and short mountain grass, ringed by peaks typical of this part of the Écrins. The Aiguille des Arias rises directly above the water, while the surrounding panorama stretches toward the Aiguille de l'Olan, the Tête des Fétoules, and further off toward the Aiguille du Plat de la Selle and the Dibona. Fed by snowmelt and glacial runoff, the water carries the turquoise tint typical of high-mountain lakes in the Alps. How do you get to Lac des Bèches? Most hikers start from the Champhorent car park, reached by road from Saint-Christophe-en-Oisans in the direction of La Bérarde, via Bourg d'Oisans and Venosc. From there, the trail follows the Muande valley up to the Refuge de la Lavey before a steep final climb to the lake itself — more than half of the total elevation gain is packed into the last stretch. The full round trip from the car park covers about 16 km and roughly 1,200 m of elevation gain, typically taking 6 to 7 hours. Hikers who overnight at the Refuge de la Lavey have a much shorter option: the climb from the refuge to the lake and back takes around 2 to 3 hours. La Bérarde, the last hamlet up the valley, is served in summer by free shuttle buses (advance booking required), which makes reaching the trailhead area possible without a car. How difficult is the trail, and who is it for? The hike is generally rated moderate to difficult, mainly because of its length, elevation gain, and the steep final approach. There's no technical climbing involved on dry ground, but a solid level of fitness and proper trekking footwear are essential. Along the way, marmots and chamois are commonly spotted on the alpine meadows and rocky slopes that define this stretch of the Écrins. Is this a protected area? Yes. The entire route runs through the Écrins National Park, one of France's largest national parks. The boundary of the park's core zone is marked with distinctive blue-white-red flags, and visitors need to respect the rules that apply there — no camping outside designated spots, no picking plants, and staying on marked paths. When is the best time to go? Given the altitude, the trail is realistically open from around June/July through September; outside that window, snow patches can linger, especially on the steep final climb near the lake. It's worth checking current conditions with the Écrins National Park office or at the Refuge de la Lavey before setting out. FAQ How high up is Lac des Bèches? The lake sits at roughly 2,400 m of altitude, in the Vallon de la Lavey. How long does the hike take? From the Champhorent car park, the round trip takes 6 to 7 hours (about 16 km, 1,200 m of elevation gain). From the Refuge de la Lavey, the climb to the lake and back is shorter, around 2 to 3 hours. Is the trail difficult? It's long and requires good fitness, with a steep section just before the lake, but there's no technical difficulty on dry terrain. Can you reach the area without a car? Yes — in summer, free shuttle buses run to La Bérarde, though advance booking is required. Is the lake inside a national park? Yes, the whole route runs through the Écrins National Park, including its core zone marked by blue-white-red flags.

Lac des Sirènes

Orcières

Lac des Sirènes is a small mountain lake sitting at 2,390 m above sea level in the commune of Orcières (Hautes-Alpes), in the Champsaur valley within the Écrins massif. It lies roughly 4 km north of the Orcières-Merlette ski resort and is one of several lakes scattered across the high pastures above Merlette that draw hikers during the summer season. Where exactly is the lake located? Lac des Sirènes sits in the upper part of the valley, above the tree line, surrounded by typical Champsaur alpine vegetation. The surrounding bedrock is made of grès du Champsaur, a coarse-grained flysch sandstone in which sandstone layers alternate with clayey schists. This rock formed during the Priabonian stage of the Upper Eocene, roughly 34 to 38 million years ago. Right at the shoreline, clayey schists dominate, giving the banks a darker, distinctive tone. What fish live in Lac des Sirènes? The lake holds Arctic char (Salvelinus alpinus), a species considered native to this water body and whose population is periodically supported through restocking. This makes the lake a destination for anglers visiting the Hautes-Alpes. How do you get to Lac des Sirènes? The most common starting point is the hamlet of Merlette, from where the round-trip hike takes about 3 hours 30 minutes with roughly 590 m of cumulative elevation gain. The route is rated easy and doesn't require specialized mountain experience. An alternative is to start from the highest car park at Orcières-Merlette (around 1,870 m), from where part of the climb can be covered using the télémix chairlift, cutting down the walking time. What else is worth seeing nearby? From Lac des Sirènes, the trail continues past Lac Long toward Grand Lac des Estaris, sitting at 2,558 m — one of the more popular hikes in the Champsaur area, crossing high alpine meadows and pastures. The valley is overlooked by several peaks, including Mourre Froid (2,993 m), Roche Brune (2,956 m), Roc Diolon (3,071 m) and Grande Autane (2,782 m), visible from many points along the route. Near Grand Lac des Estaris lies a protected cirque where additional restrictions apply to dogs. Frequently asked questions At what altitude is Lac des Sirènes? The lake sits at 2,390 m above sea level, in the commune of Orcières. How long does it take to reach the lake? From the hamlet of Merlette, the round trip takes about 3 hours 30 minutes, with around 590 m of elevation gain. Can you fish in the lake? Yes, Lac des Sirènes holds Arctic char, and the population is supported through periodic restocking. Is the trail difficult? The section leading to Lac des Sirènes is rated easy and suitable for hikers with average fitness, and the walking time can be shortened using the chairlift from Orcières-Merlette. Can this hike be combined with other lakes? Yes — the trail continues past Lac Long to Grand Lac des Estaris, forming a loop that is popular with visitors to the Écrins massif.

Lac du Vallon

Chantepérier

Lac du Vallon is a mountain lake sitting within the commune of Chantepérier, in the Isère department of the Auvergne-Rhône-Alpes region, right at the edge of the Ecrins massif. Perched at an altitude close to 2,500 metres, it is ringed by rocky ridgelines that keep this corner of the French Alps quiet and rarely crowded, even in high season. Reaching it takes real effort, but the reward is a wide-open alpine panorama few day-trippers ever see. Where exactly is Lac du Vallon? The lake lies on the territory of Chantepérier, though most hikers set off from the neighbouring village of Chantelouve, which serves as the main trailhead. Both villages sit in Isère, close to the boundary of Ecrins National Park, in a stretch of the Alps known for stark, rocky terrain and far fewer visitors than the better-known Oisans valleys nearby. How do you get there on foot? A marked trail leads up to Lac du Vallon, and it is a steep one — from Chantelouve, plan on roughly three hours of climbing to reach the lake. Hikers aiming for a full loop around the surrounding ridges should expect a route stretching well over ten kilometres and a full day out on the mountain. This is not a stroll for casual walkers; it suits people already comfortable with long, high-altitude hikes and significant elevation gain. What views does the lake offer? Lac du Vallon sits at the foot of the Rochail summit, framed by rocky crests on several sides. From its shores, the panorama opens onto the Oisans massif and the Taillefer peak, two of the defining landmarks of this part of the Dauphiné Alps. The scenery shifts from bare rock and scree near the water to alpine meadows lower down the trail, giving the hike a varied character from start to finish. Who should plan this hike? Given the altitude, the length of the approach, and the exposed terrain, Lac du Vallon is best suited to experienced mountain hikers used to long days with substantial elevation gain. An early start is worth planning for, along with gear suited to the fast-changing weather typical of high alpine terrain, and it is wise to check current trail conditions before setting out, particularly outside the summer months. FAQ Where is Lac du Vallon located? The lake lies within the commune of Chantepérier in the Isère department, in the Auvergne-Rhône-Alpes region, on the edge of the Ecrins massif, close to the village of Chantelouve. How long does the hike to the lake take? From Chantelouve, the climb takes around three hours one way. A full loop around the surrounding trails runs well over ten kilometres and takes most of a day. Is the trail difficult? Yes. The route involves significant elevation gain over high-mountain terrain, so it is recommended for experienced hikers rather than beginners. What can you see from the lake? The lake offers views of the Rochail summit along with a wider panorama taking in the Oisans massif and the Taillefer peak, making it a rewarding destination for lovers of high-alpine scenery. Is there another lake with a similar name nearby? France has another lake with a very similar name in Haute-Savoie, formed by a landslide, but it is an entirely separate body of water in a different region, unrelated to the Lac du Vallon in Isère.

Étang de la Bornière

Bain-de-Bretagne

Étang de la Bornière is a roughly thirty-hectare pond sitting right at the heart of Bain-de-Bretagne, a small town in the Ille-et-Vilaine department of Brittany. Locals also call it étang de Bain or Lac de Bain-de-Bretagne. The pond traces its origins back to the local tanning industry, which shaped the town's economy in the late 19th and early 20th centuries, and it still stands as a quiet reminder of that industrial past. What is there to do around the pond? The area around the water is split into three zones, each with its own purpose: one set aside for anglers, one for water sports, and one left as a refuge for local wildlife. This layout lets visitors enjoy the pond without crowding out the birds and aquatic plants that live along its banks. In summer the water comes alive with sailing, canoeing and kayaking, and windsurfing, all organized through the Club Nautique Bainais, the local water sports club based on site. Swimming itself is not allowed, but sandy stretches along the shore give visitors a place to sit, spread a blanket, or picnic in the shade. Can you fish here? Fishing is one of the main draws of Étang de la Bornière. You can cast a line from the bank or fish from a non-motorized boat, though boat fishing requires clearance from the local angling association, AAPPMA L'Union des Pêcheurs de Bain. Access is non-reciprocal, meaning a standard AAPPMA card is not enough on its own — anglers also need a separate permit specific to this pond. The water holds pike, roach, and carp, and a dedicated stretch is set aside for night carp fishing sessions. What about walking or cycling? A green path circles the entire pond, following the former Ploërmel–Châteaubriant railway line, which carried passengers and freight between 1896 and 1986. The full loop runs about 5.3 kilometers and takes roughly an hour and twenty minutes on foot at an easy pace, starting from the parking area near the town's swimming pool. The route is flat and accessible, making it just as suitable for families with children as for cyclists looking for a short, scenic ride. Who is this spot for? Étang de la Bornière is a classic example of a rural Breton pond that grew into a genuine local recreation hub. It suits anglers after a quiet spot to fish, families planning an easy loop walk around the water, and — come summer — anyone drawn to sailing or paddling under the guidance of the local club. There is nothing flashy about it, but its industrial backstory and everyday local character give it a sense of place that larger, more famous sites often lack. Frequently asked questions How big is Étang de la Bornière? The pond covers approximately 30 hectares. Is swimming allowed in the pond? No, swimming is prohibited, though sandy areas along the shore are available for relaxing by the water. Do you need a special permit to fish there? Yes. Besides a standard AAPPMA membership card, anglers need an additional permit specific to this pond, since access is not reciprocal with other fishing waters. What fish live in the pond? The pond is home to pike, roach, and carp, among other species. What is the history behind the pond? It is linked to the development of local tanneries in the late 19th and early 20th centuries, a chapter of industrial history still tied to Bain-de-Bretagne's identity today.

Lac de Bonnal

Chassey-lès-Montbozon

Lac de Bonnal is a cluster of five bodies of water in the commune of Chassey-lès-Montbozon, in the Haute-Saône department, part of the Bourgogne-Franche-Comté region of eastern France. Rather than a single natural lake, it forms a large recreational estate along the Ognon river, spread over roughly 150 hectares of woodland and open water, and is often referred to locally as the Domaine du Val de Bonnal. Where exactly is it? The site sits between the towns of Rougemont and Villersexel, in the north-eastern corner of Haute-Saône, close to the border with the Doubs department. Its coordinates are approximately 47.52°N, 6.37°E. The surrounding landscape is quiet farming and forest country, reached by minor roads rather than a motorway, which gives the area a genuinely rural feel far from any large city. What can you do on the water? Of the five bodies of water, one is set aside purely for swimming. Through the summer season — typically July and August — the beach is watched over by lifeguards, making it a reassuring option for families. Pedal boats, canoes and paddleboards can be hired on site, usually charged by the half hour. Away from the water, there are courts for beach volleyball and pétanque, plus a walking path of several kilometres that loops around the lakes — a pleasant way to close out a day spent by the water. Is fishing allowed? Yes. Two of the five lakes, similar in size to one another, are reserved specifically for anglers. This is also where the annual "24 Hours of Fishing at Bonnal" takes place, an event that draws fishing enthusiasts from across the wider region. The remaining bodies of water are mostly given over to leisure use or sit alongside the estate's overnight cabins. Can you stay overnight? Part of the estate around the lakes is occupied by wooden cabins belonging to a nature-lodge operator, with views over the water and surrounding forest. This suits visitors who want more than a day trip — waking up beside the lake rather than simply passing through for an afternoon swim. When is the best time to visit? The supervised swimming season runs through the summer holidays. Outside that window, the site still works well for walking, fishing or simply relaxing outdoors, though without a lifeguard on the beach. Entry to the grounds typically carries a small admission fee, with young children let in free, and it's worth checking opening hours before setting off since they shift with the season. Frequently asked questions Is Lac de Bonnal a single lake? No — it's a group of five bodies of water within the roughly 150-hectare Domaine du Val de Bonnal estate. Can you swim there? Yes, one of the lakes has a sandy beach with lifeguard supervision during the summer season. Is there fishing? Yes, two of the lakes are dedicated to fishing, and the site hosts an annual round-the-clock fishing competition. Where precisely is it located? In the commune of Chassey-lès-Montbozon, Haute-Saône department, between the towns of Rougemont and Villersexel. Can you stay overnight on site? Yes, wooden cabins overlooking the lakes and forest are available to rent.

Lake Gignoux

Cervières

Lake Gignoux sits at 2,329 metres on the south-facing slope of the Cerveyrette valley, within the commune of Cervières in the Hautes-Alpes department, part of the Briançonnais area of the French Alps. It lies just east of the Chenaillet summit (2,650 m), close to the ridge that marks the border with Italy, and is one of several small alpine lakes reached on foot from the village of Cervières. How big is the lake and what does it look like? Lake Gignoux covers roughly 1.9 hectares, set among scree slopes and moraine in a stark, mineral landscape typical of this part of the Alps. Locals and hikers sometimes call it the "lake of seven colours," a nickname tied to how its surface shifts between deep blue and pale green depending on light, depth and time of day. That shifting palette, more pronounced here than at many neighbouring tarns, is a large part of the lake's draw for hikers and photographers. What peaks and other lakes surround it? The ridgeline north of the lake forms part of the French-Italian border. Visible from the shore are Cime de Saurel (2,449 m), Grand Charvia (2,648 m) and Pic de Peyre Eyraute (2,903 m), while the nearby Col de Gimont provides a link toward the Susa valley on the Italian side. A short stretch along the approach trail passes Lac Noir (2,226 m), a smaller lake often visited on the same outing. Why does the geology here stand out? The rock around Lake Gignoux includes basalt and gabbro outcrops exposed among the scree and moraine — remnants of ancient oceanic crust. Geologists trace these formations to the Liguro-Piedmont Ocean, part of the wider Tethys Ocean roughly 150 million years ago, when the seabed here lay some 3,000 metres deep. For visitors with an interest in Alpine geology, the lake basin offers a rare, accessible cross-section of that deep past. What plants and animals live around the lake? The area is recognised as a protected natural site. It supports around a dozen rare plant species, two of them under national protection, adapted to the subalpine and alpine belts that surround the lake. Wildlife recorded in the vicinity includes red deer, rock partridge, black grouse and the Apollo butterfly, a species often used as an indicator of well-preserved high-mountain habitat. How do you get there and how long does the hike take? Access is via the D89T road up the Cerveyrette valley from Cervières, with parking near the old La Chau farms at around 1,893 m. From there, the trail passes the Sainte-Elisabeth chapel toward the Fraches sheepfold before climbing to the lake. The direct round trip takes about 2 hours 45 minutes with roughly 450 m of elevation gain. A longer, popular loop links Lake Gignoux with Lac Noir and Lac des Sarailles — about 10 km and 500–650 m of climbing, taking 4 to 5 hours. The route is considered suitable for families but is poorly marked in places, so carrying a map or GPS track is worthwhile. Unlike the busier north-facing slopes nearby, this side of the valley is dry and has no ski infrastructure. FAQ How long does it take to reach Lake Gignoux? From the La Chau parking area, the round trip is about 2 hours 45 minutes, gaining roughly 450 metres in elevation. Is the trail difficult? No — it's rated a family hike, though some sections are poorly marked, so a map or GPS track helps. Can the visit be combined with other lakes? Yes. A popular loop connects Lac des Sarailles, Lake Gignoux and Lac Noir over about 10 km and 4 to 5 hours. Why is it called the "lake of seven colours"? Because its water shifts between shades of blue and green depending on depth, light and time of day. Is there any ski infrastructure nearby? No. The south-facing slope of the Cerveyrette valley is dry and undeveloped for skiing, unlike the north-facing slopes in the area.

Lac Mouriscot

Ustaritz

Lac Mouriscot is a lake and protected natural area in Biarritz, in the Pyrénées-Atlantiques department of France's Basque Country. It sits right on the border with the neighbouring town of Bidart, roughly 1750 metres from the Atlantic shoreline, and forms a pocket of greenery inside one of the most built-up seaside resorts on the French Basque coast. Where exactly is the lake? The site sits at approximately 43.4556 N, -1.5594 W. Lac Mouriscot fills a small valley enclosed by wooded, fairly steep slopes that drop toward the water almost like natural ramparts, planted with pines, oaks, and beeches. The vegetation grows thicker and wilder the further you move from the shoreline. The lake is occasionally confused with another Basque commune, Ustaritz, about 10 km further south - in fact, the entire lake lies within the boundaries of Biarritz. What kind of protected site is this? Lac Mouriscot is classified as an ecologically sensitive site within France's network of protected coastal land. In 1997, the Conservatoire du littoral purchased the land around the lake from the city of Biarritz - more than 24 hectares in total - while day-to-day management stayed with the municipality. The broader natural area around the lake, including its surrounding wetlands, extends over several dozen hectares. Within that space, several distinct habitats sit side by side: a eutrophic lake, Atlantic heathland, lowland peat bog, sedge marsh, and stretches of ancient woodland and alluvial forest - an unusually varied mix for a site so close to the Atlantic coastline. What wildlife lives around the lake? Close to 70 bird species pass through or settle around Lac Mouriscot, especially during migration and over winter - grey herons, kingfishers, and birds of prey are regularly spotted circling the valley. The water itself holds carp, pike, tench, gudgeon, eel, and perch. Dense reeds and marshy ground keep parts of the shoreline hard to reach, which helps the site keep its wild character despite sitting inside an urban area. Can you fish or swim here? Fishing is allowed without a licence, but only from the bank - no boats - and limited to one rod per angler. A water-sports facility operated on the lake until the 1960s; today, though, the site is mainly used for walking and birdwatching rather than swimming or paddling. How do you get there, and what trails connect to it? Lac Mouriscot is within walking distance of central Biarritz, surrounded by villa neighbourhoods and nearby golf courses. It forms one stop along the "Chemin des Lacs," an approximately 8-kilometre walking route that starts at Milady beach, passes the neighbouring Lac Marion, reaches Lac Mouriscot, and finishes at the Cité de l'Océan. The site itself is open to visitors around the clock and free to enter. What's the history behind the site? Traces of human presence at the lake go back to prehistoric times. From the 1880s onward, wealthy families began building grand villas around its shores, among them Villa Mouriscot, Villa Barbarenia, and the Françon estate. During the First World War, military seaplanes reportedly landed on the lake, a detail that hints at its earlier logistical role in this stretch of the coast. Frequently asked questions Is Lac Mouriscot located in Ustaritz? No. The lake lies entirely within the town of Biarritz, on the border with Bidart. Ustaritz is a separate Basque commune about 10 km further south and has no direct connection to this lake. Is there an entry fee? No, the area around the lake is open to the public free of charge, at any time of day. Can you fish at Lac Mouriscot? Yes, no fishing licence is required, but angling is limited to the shoreline, with a maximum of one rod per person. Can a visit here be combined with a longer walk? Yes, Lac Mouriscot is one of the stops on the "Chemin des Lacs," a roughly 8-kilometre route running from Milady beach, past Lac Marion, all the way to the Cité de l'Océan.

Lac de Villegusien

Longeau-Percey

Lac de Villegusien is a man-made lake in the Haute-Marne department, in the Grand Est region of France, near the commune of Longeau-Percey. Locals also know it as Lac de la Vingeanne, after the river that feeds it. Covering just under 2 km², it ranks among the larger bodies of water in this quiet corner of Champagne, drawing summer visitors who come for swimming, watersports, and an uncrowded day by the water. How did this lake come to exist? The lake did not form naturally — it was built to supply water to the Canal entre Champagne et Bourgogne, the waterway linking the Marne and Saône river basins. Reservoirs of this kind are common across Haute-Marne, where a hilly, valley-rich landscape made it practical to dam streams and store water for inland navigation. Over time, the lake's original engineering purpose has taken a back seat to its role as a recreation spot. What is there to do at the lake? A watersports centre on the shore serves both beginners and seasoned enthusiasts. Visitors can sail, rent a canoe, or try windsurfing and stand-up paddleboarding on the sheltered water, which suits people learning these sports for the first time. Footpaths and cycling routes circle the lake, letting visitors walk or ride its perimeter while taking in waterfowl and views of the surrounding Haute-Marne hills. Is swimming allowed? Yes. A supervised bathing area with a sandy shore sits along the lake, well suited to families. During the summer lifeguard season it becomes a natural gathering point for parents with children, thanks to shallower water near the bank, shaded picnic spots, and nearby parking that make a full day at the lake easy to plan. Outside the supervised season, swimming is at one's own risk, so it is worth checking current opening times before setting out. Is the lake good for fishing? Lac de Villegusien is also a recognised fishing spot. Anglers cast from the bank or from boats for carp and pike, species typical of reservoirs with dense shoreline vegetation that favours predatory fish breeding. As on most inland waters in France, fishing here requires a valid fishing licence. Events and local atmosphere The lakeside village of Villegusien-le-Lac is known locally for a summer festival built around kite flying, which draws enthusiasts from across the region on warm weekends. It is one more reason to time a visit for the summer months, when the shoreline is at its liveliest. The surrounding area, in and around Longeau-Percey, is largely agricultural and forested, with far less tourist traffic than France's better-known destinations. The lake acts as a natural focal point for outdoor leisure here, without the crowds typical of more famous resorts. FAQ Where exactly is Lac de Villegusien located? In the Haute-Marne department, within the commune of Longeau-Percey, near the village of Villegusien-le-Lac, at approximately 47.7456 N, 5.3125 E. Is the lake natural? No, it is an artificial reservoir, built to supply water to the Canal entre Champagne et Bourgogne linking the Marne and Saône rivers. What watersports are available? Sailing, canoeing, windsurfing, and stand-up paddleboarding, through the local watersports centre. Is there a supervised swimming area? Yes, a lifeguard-supervised beach with a sandy shore operates in summer and is well suited to families. Can you fish at the lake? Yes, it is stocked with species such as carp and pike; a valid fishing licence is required.
