The Grande source and its streams gush out in a small wood at the foot of Mont-Mussy. They form the main source of La Divonne, a 22 km long river, which flows into Lake Geneva, in Switzerland, at Versoix.

One of the most beautiful viewpoints over the Alps that I know! Access from the Col de la Faucille is quite simple.

A magnificent forest loop. Suitable for all levels, with 200m/20km of really technical sections - easily done on foot.

It's rare to find such beautiful, unspoiled rivers. There are alternating small waterfalls, wild spots, and quiet areas where the water accumulates. Fallen trees are welcome to stay. The path always follows the banks. Suitable footwear and a little surefootedness won't hurt.
