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.

The greenway connecting Gex to Divonne-les-Bains is an easy and pleasant developed route that crosses the green landscapes between the Jura mountains and Lake Geneva. In Divonne, several routes provide easy access to its lake, as well as the mountain bike trails of Mont Mourex, which are very popular with nature and thrill-seekers.

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

An opportunity to avoid riding near cars. It's a shame we have to slow down so often to pass the gates that stop cars.

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.

Very nice access paths and landscape. There are two sections a bit more technical but doable by average rider like me. First section going up to Mont Mourex (road with some round rocks and a bit muddy when it rains). Second section on the way to the longest loop where the trail is a bit narrow and deep (probably due to rain water going through during winter). In any case, is doable. Just take your time and keep focus :) Definitely a ride to do more times
