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.

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