Chamonix has number of dedicated mountain biking areas at the top & bottom of the valley and lots of natural single track which you can either access by lift or bike up.
There are around 20 official marked trails of varying difficulty, marked on the downloadable Chamonix Valley trails map, giving you access to descents from -500m to -1,500m. In addition to these trails though is a huge network of trails from novice friendly 4x4 tracks to steep, technical goat tracks that can test even the best riders.
Popular trails along the valley floor include the Petit Balcons Nord and Petit Balcons Sud, and area around Les Bois (2km north of Chamonix) also offers a variety of trails for all abilities. The valley's trails vary in length from a couple of km to the Chamonix-Le Tour-Chamonix at about 30km.
Compagnie du Mont Blanc is encouraging mountain biking the in quieter areas of Les Houches and Le Tour at either end of the valley and have built a number of dedicated downhill trails from the lifts.
The Brevent, Flegere and Grand Montets lifts also all allow for bike uplift and, whilst there are no purpose built trails, lots of excellent riding awaits those ready for the challenge.
One point to note is the restrictions on mountain biking in July and August, read on for more information on what you can and can’t ride during this time.
