Explore one of the most beautiful itineraries in the Écrins. A wild trail, a high-altitude lake, an authentic refuge... the perfect backdrop for a memorable getaway in Les 2 Alpes.
Leaving from Venosc, the hike to the Muzelle lake and refuge promises total immersion in the majestic landscapes of the Écrins massif. Between dense forests, crystal-clear waterfalls and peaceful mountain pastures, the trail rises to reveal an altitude jewel nestled at 2,130 meters. Accessible to regular walkers, this emblematic route seduces by its authenticity and the raw beauty of its panoramas. Every step brings you closer to the soothing silence of the peaks and the reflection of the glacier on the calm waters of the lake. An unmissable adventure for nature lovers and mountain escape seekers.
A spectacular glacial lake perched 2,130 metres above sea level Lac de la Muzelle emerges after several hours' ascent, like a reward suspended between sky and summit. Nestled at an altitude of 2,130 metres, it lies at the foot of the imposing Muzelle summit and its glacier. Fed by meltwater, this glacial lake reveals shades of blue that change with the light and the seasons. In summer, its limpid waters reflect the sheer walls that surround it, creating a landscape of rare majesty. Protected by the Ecrins National Park, the area retains an unspoilt, almost silent atmosphere.
Reflections, silence and serenity: the unique experience of the lake in summer By the lake, time seems suspended. The silence is disturbed only by the wind blowing through the alpine grasses or the piercing cry of a marmot. The gaze is lost in the glacier's shimmering reflections, the sharp peaks and the breathtakingly calm waters. Summer here offers a timeless interlude, ideal for contemplation or meditation. Some dare to go barefoot in the icy water, others prefer to lie down in the short grass to enjoy a siesta facing the heights. The lake alone embodies the wild essence of the Alps.
Photography and observation: the ideal times to enjoy the panorama For photography enthusiasts, morning and evening light are the best times to capture the magic of the site. Dawn reveals sharp contrasts on the rock faces, while twilight envelops the lake in golden softness. Reflections become almost unreal. Binoculars and spotting scopes can also be used to spot chamois on the ridges or eagles flying over the valley. In all seasons, but especially in summer, the alpine light transforms this landscape into a living tableau, ideal for contemplative and nature-loving visitors.
Respect for the site and protection of the natural heritage As Lac de la Muzelle is located in the heart of the Ecrins National Park, it is subject to strict regulations. It is forbidden to camp, light fires, pick flowers or disturb wildlife. Swimming is tolerated but not recommended, both for safety reasons and to preserve the fragile ecosystems. All visitors are asked to take their garbage with them and to be discreet in the face of nature. Preserving this natural jewel means guaranteeing that future generations will be able to enjoy it intact.
Getting to the starting point: how to reach the hamlet of Bourg-d'Arud This exceptional hike starts from the hamlet of Bourg-d'Arud, right next to the village of Venosc. Accessible from the resort of Les 2 Alpes by gondola or by car via the Vénéon valley, this typical little village nestled at the foot of the mountains is an ideal gateway to the wild landscapes of the Ecrins National Park. The path starts near the church, skirting the torrent, then quickly rises into a wooded environment. Easy to reach, the starting point is well signposted, with a small parking lot available for hikers.
Route overview: distance, duration, elevation gain and signposting The route to Lac de la Muzelle is classified as of medium to high difficulty, due to its significant elevation gain. Allow around 7 hours round trip for a total distance of 17 kilometers and an ascent of around 1,200 meters. The trail is marked in yellow and well-maintained, but requires good stamina. The climb is continuous and sometimes steep, especially on the final winding section before the pass. This hike is aimed primarily at regular hikers in good physical condition, looking for a wild and immersive itinerary.
What to expect: alpine ambience, flora, fauna and remarkable views As you climb, the forest gradually gives way to alpine meadows, then to high-altitude mineral landscapes. The path skirts waterfalls, streams and wetlands populated by cottongrass. The biodiversity here is remarkable: marmots, chamois and golden eagles can sometimes be seen. The panorama gradually unfolds to offer breathtaking views of the Vénéon valley, the Venosc ridges and, in the distance, the glacial peaks of the Écrins massif. The feeling of solitude and disconnection is enhanced by the unspoilt nature of the area, far from any hustle and bustle.
Best times to go and weather recommendations Hiking to Lac de la Muzelle is possible from late June to early October, when the snow has disappeared from the heights. The summer period, from mid-July to the end of August, offers the best conditions, with pleasant temperatures and flora in full bloom. We strongly advise you to set off early in the morning to avoid extreme heat, high altitude thunderstorms or crowds on the trail. Always check the weather forecast the day before you set off: fog or rain can make certain sections slippery or blur visual reference points.
History and charm of the refuge: a blend of tradition and mountain hospitality Perched at an altitude of 2,135 metres, the Muzelle refuge stands in a spectacular setting on the very edge of the eponymous lake. Built in 1967 and subsequently renovated, it embodies the spirit of high-altitude refuges: simplicity, a warm welcome and breathtaking panoramic views. Its silhouette of stone and wood blends perfectly with the Alpine scenery. A stopover for hikers on the GR54 (Tour de l'Oisans), it is also a destination in its own right for those seeking complete immersion in the mountains, between conviviality and voluntary isolation.
Services offered: accommodation, catering, booking recommended The Muzelle refuge has a capacity of around 40 beds, divided into dormitories. Blankets, drinking water, sanitary facilities and homemade Savoyard cuisine based on simple, nutritious ingredients are all available. Pies, soups and hot dishes help you regain your strength after the climb. Breakfast at sunrise, with a view of the rosy mountains, is one of the suspended moments offered by this unique place. In high season, reservations are highly recommended, especially for weekend nights and busy periods.
Practical advice for a night in a refuge: equipment and atmosphere Spending the night in a refuge requires a minimum of anticipation. It's essential to bring a sleeping bag or sheet, a headlamp and warm clothing, even in summer. The atmosphere is often convivial, conducive to exchanges between hikers from all horizons. The rhythm follows that of the sun: dinner early, sleep with the night, wake up at dawn. Silence reigns from 9 p.m. onwards, to respect everyone's rest. This experience, both sober and rejuvenating, is an integral part of the charm of the high mountains.
Nearby activities: hiking and wildlife watching From the refuge, there are several routes for experienced hikers. The ascent to the Col de la Muzelle, at 2,613 meters, offers panoramic views of the surrounding peaks. Other variants take you to Lac Lauvitel or on to the GR54. It's also an excellent vantage point for spotting ibex, marmots and bearded vultures in their natural habitat. The environment of the refuge, with its scree slopes, névés and high-altitude meadows, is ideal for a break in the heart of a wild and unspoilt area.
Required level and trail profile: for experienced hikers The trail leading to the Muzelle lake and refuge is aimed primarily at experienced hikers. The profile is demanding, with 1,200 meters of positive ascent on sometimes steep terrain. Some sections include tight switchbacks, stony passages and a steep final climb before arriving at the lake. Good physical condition, regular walking and experience of long mountain outings are highly recommended. For lovers of alpine challenges without the need for mountaineering, this route offers a complete experience between physical effort and wild beauty.
Essential equipment for a safe hike Having the right equipment is the key to making the most of this high-altitude adventure. High-top hiking boots, ergonomic backpack, windbreaker, sun protection and layered clothing are essential. A water reserve of at least 2 liters, energy snacks, an IGN map or a reliable GPS application ensure autonomy and safety. Walking poles are recommended to take the strain off your joints, especially on the descent. If you're spending the night in a refuge, a meat bag, a headlamp and a few changes of clothes are the ideal extras.
Easier alternatives for families or occasional walkers For those who wish to discover the Vénéon landscape without committing themselves to such a strenuous hike, several accessible walks are available from Venosc or Bourg-d'Arud. The Plan du Lac trail or the walk to the Muzelle waterfall offer a technically easy way to immerse yourself in Alpine nature. Accompanied hikes offered by local guides also provide a reassuring and rewarding alternative, especially for families and beginners. These options give you a gentle taste of the mountains.
Good mountain practices: marking, cleanliness, respect for the environment Hiking in a natural environment requires responsible behavior. Following official signs, staying on trails and not cutting corners protects fragile soil. All hikers are asked to bring back their own garbage, avoid picking plants or making noise. In the Parc national des Écrins, certain areas are protected: dogs are forbidden, drones are prohibited and wild camping is forbidden. Adopting these simple gestures means actively contributing to the preservation of Alpine ecosystems and ensuring the long-term future of these exceptional landscapes.
Between unspoilt nature, grandiose panoramas and an authentic refuge, the hike to Lac de la Muzelle offers an unforgettable experience in the heart of the Alps.
