When you think of the Alps, you might readily picture snow-capped peaks and lush mountain pastures... But these majestic mountains are also home to magnificent alpine lakes, often nestled at over 2,000 metres in altitude: deep blue or emerald green, fringed by rocks, forests or flower-filled meadows. Among the most spectacular, here is a selection of Alpine lakes well worth the detour, whether on foot, by mountain bike or simply with a good picnic in your backpack!
The 6 most beautiful lakes in the Alps
1. Lac de Trécolpas: pure nature in the Mercantour
Perched at 2,150 metres in the Mercantour National Park, Lac de Trécolpas is one of the gems of the Alpes-Maritimes. After a fine hike up from the Vésubie valley, walkers reach the lake via a switchback trail lined with Swiss stone pines and larches.
The reflections of the surrounding mountains create an almost unreal atmosphere. It's a perfect spot to take a break, set down your pack, share a picnic facing the crystal-clear waters and, if you're lucky, spot a few chamois or marmots. Trécolpas remains a little corner of paradise, far from the crowds!
2. Lac de Rabuons: wild vastness
Head to the Alpes-de-Haute-Provence, near Saint-Étienne-de-Tinée, to reach Lac de Rabuons. This vast mountain lake, perched at 2,500 metres, impresses with its size and the raw power of its rocky surroundings.
The climb is demanding but unforgettable. Once at the lake, you discover a mirror of glacial water ringed by sharp peaks whose colours shift with the hour and the light. It's a raw, mineral, breathtaking setting, where you can feel the quiet strength of the mountain air. For the most motivated, a night at the Rabuons refuge lets you witness the sunrise in this grandiose landscape.
3. Lac de Serre-Ponçon: grandeur and water sports
Further south, on the border between the Hautes-Alpes and the Alpes-de-Haute-Provence, Lac de Serre-Ponçon stands out. This is no small, isolated lake but a vast body of water covering 28 km², one of the largest artificial lakes in Europe.
Built in the 1960s to regulate the Durance river, the lake has become a popular holiday destination with its landscaped beaches, wild coves accessible by paddleboard or kayak, and countless water activities: sailing, water-skiing, paddleboarding, swimming and more.
But Serre-Ponçon also offers an exceptional view of the surrounding mountains and an iconic landmark: the Saint-Michel chapel, a tiny building set on an island in the middle of the lake. It is the only remnant of the former alpine village of Savines. A mystical place, especially at sunset.
4. Lac d'Allos: the largest natural high-altitude lake in Europe
Staying in the Alpes-de-Haute-Provence, Lac d'Allos is often hailed as France's most remarkable lake for its surface area at this altitude (2,230 m). Located in the heart of the Mercantour National Park, this magnificent lake draws hiking enthusiasts and contemplative souls alike.
Reached by a family-friendly trail from the Laus car park, the lake appears after an hour's walk like the ultimate reward: an expanse of turquoise water surrounded by jagged ridges where a few ibexes sometimes graze. On its shores, a picnic or a nap in the sun seems to suspend time. The more adventurous can continue on to the nearby Petite Cayolle or Lausson lakes.
5. Lac de Chantemerle: discreet charm
Less well known than its neighbours, Lac de Chantemerle is tucked away in the mountains of the Haute-Maurienne: a hidden pearl. Accessible from the hamlet of the same name, this small lake sits at nearly 2,400 metres, away from the classic tourist trails.
It's the ideal place to feel alone in the world, to observe nature in its intimacy and to savour a soothing landscape. In summer, the banks welcome hikers who come to fish for rainbow trout, cool off or simply breathe deeply.
6. Lac du Mont Cenis: between France and Italy
Finally, on the Franco-Italian border, Lac du Mont Cenis is intriguing. Set on a former strategic pass, this vast artificial lake reveals an intense blue colour (almost surreal!) in a landscape that is at once alpine and lunar.
Surrounded by high-altitude meadows and military remains, the site lends itself to hiking, cycling and quiet contemplation. Several trails run along the shores or climb towards the surrounding peaks to reward you with a magnificent panorama over the centre of the lake and the surrounding Alpine range. On a clear day, you can even glimpse the Italian glaciers in the distance!
Other alpine lakes to discover
Lac de la Muzelle (Isère)
Nestled at 2,100 metres, at the foot of a glacier in the Écrins massif, this wild lake has to be earned after a good climb up from the Vénéon. At Lac de la Muzelle, you'll find a dark mirror of water, often surrounded by snowfields even in summer and overlooked by the majestic Roche de la Muzelle.
Lac Vert (Haute-Savoie)
Located near Passy, the enchanting little Lac Vert is famous for its emerald-green reflections, which come from its aquatic vegetation. Easy to reach and perfect for a family picnic, it offers a peaceful setting with a view of Mont Blanc on clear days. It's a charming stopover in the forests of Haute-Savoie.
Lacs Robert (Chamrousse)
These high-altitude lakes, sitting at 1,980 metres in the Belledonne massif, are easily accessible thanks to the Chamrousse ski lifts. We recommend the Lacs Robert for an easy stroll, a refreshing swim (for the brave!) or a first go at fishing: it makes a fine half-day hiking objective.
Lac du Bourget (Savoie)
France's largest natural lake, Lac du Bourget blends an urban atmosphere (Aix-les-Bains) with unspoilt nature. You'll find many viewpoints, but the most spectacular remains the one from Hautecombe Abbey, perched above the water. The sunset there is simply magical!
Lacs des Sept Laux (Isère)
This string of lakes perched at over 2,000 metres in the Belledonne massif is a true paradise for seasoned hikers. The climb from Fond-de-France or Prapoutel is demanding, but each lake reveals a different character: clear, deep, suspended. It's a complete alpine adventure, with the option of an overnight stay in a refuge.
