The Onde Valley and its river
The Vallée de l’Onde: wild immersion all year round
Welcome to one of the most secluded and unspoiled valleys in the Pays des Écrins. L’Onde is the turquoise-watered stream that winds its way at the foot of the Aiglière, creating a wild and peaceful setting that you can explore year-round. Each season reveals a new facet of this place, one that’s always just as breathtaking.
In summer
Summer is pure adventure. Hiking, trail running, camping—you set the pace. Want some peace and quiet? Stay down in the valley. Want to get up high? Climb toward the peaks in the area. The evenings are long, the stars are shining, and the air smells of pine resin.

In autumn
In the autumn, it’s time for the fire of the larches. This is perhaps the most magical season. Few people, flamboyant colors, golden light… The Wave becomes wild, mysterious, almost confidential.
In winter
In winter, it’s all about gliding gently across the snow. From Vallouise, cross-country skiers set off toward the Gresonnières cabin. The trail follows the frozen river, winding through crystalline trees and absolute silence. No need to be a skating pro—here, you take your time. Two hours is enough for a round trip and to take in the breathtaking views. You can also swap your skis for snowshoes for a peaceful, frosty hike.

In spring
In spring, water becomes the queen of the valley. The melting of the snow swells the Wave, its clear waters dance between the rocks, and the meadows are covered with flowers. It’s the perfect time for a quiet walk or a picnic in the sun. The most curious ones head to the confluence of the Bans and the Selle torrents, where the Onde is born.
