Les Bois Map

While Chamonix is renowned as a radically-challenging mountain destination, the valley still offers a small trail system that's perfect for the absolute newbie mountain biker: the Les Bois trails. This network of trails and dirt paths inhabits a stand of tall trees along the banks of the river.


The route mapped here is just one recommendation from the Chamonix Board of Tourism for an itinerary in this area. This small forest is a complex network of wide dirt paths and narrow singletrack trails that are constantly intersecting, splitting, and junctioning with other trails. Trying to follow a specific route through this area can be confusing, so it’s best to just pick a general direction that you’d like to go and pick the type of track that you’d like to follow.

For an easier ride, stick to the wide, gravel paths. With almost no elevation gain and no technical obstacles, these provide the easiest biking you’ll find anywhere.

In between the gravel paths there are a few flat singletrack trails. Since these trails traverse such a flat woodland zone, they are quite rooty and can be wet if it’s rained recently. Choose these trails for a slightly more challenging ride.

If you’d like to continue your ride beyond the route detailed here, the options are endless! Consider connecting to the Chamonix Valley Gravel Ride or the Petit Balcon Loop.



Mostly smooth and non-technical singletrack with unavoidable obstacles 2in/5cm tall or less. Avoidable obstacles may be present. Ideal for beginner riders.
