Oursière Waterfall

Highlight • Waterfall

If you are looking for freshness, you have come to the right place here. This small paradise of vegetation around the waterfall is also the territory of marmots. Open your eyes !

La Pra Refuge

Highlight • Rest Area

Great refuge, for those who want to camp, go to Lake David, it's a 45-minute walk from the refuge, there's no one there and it's super beautiful!

June 22, 2025,Boucle cascade de l'Oursière - Lac Merlat, refuge de la Pra et lac David - Au départ du parking de la Gafe

A route with a nice elevation gain, easy to extend or shorten depending on your motivation. Lots of water points: waterfall, stream, lake. You can drink and eat at the Pra refuge for lunch instead of picnicking. A few difficult sections on my route, but nothing really dangerous.
