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.

Very nice ride. Access routes very nice and safe. The way up to access Mont Mourex parking is a bit technical mainly because of round rocks but easily doable. The Rochassons trail is very nice...a real ride in the park. There is only one section where the trail goes down and is a bit in V shape (maybe because of water during winter). Just take your time and keep focus. Is doable but keep focused. The view from Mont Mourex is great, specially if you are lucky with the weather. Its a very nice 360 view and a nice way down back to the parking.
