Les Bois has beautiful forest trails which are very popular with locals and tourist alike. The Mer de Glace glacier used to reach all the way into the valley near Les Bois and the glacier has shaped the land and brought down big boulders making that area into arguably the most beautiful forest in the valley. Think large moss covered boulders and rock formations in a beautiful pine forest. 

In the winter the majority of the wider trails in Les Bois are turned into cross country skiing pistes. There also marked snowshoeing trails. There are many trails and little routes you can make for yourself in Les Bois and you never to worry too much about taking a wrong turn. This particular trail is a short loop which in my combines some of the best trails in Les Bois with a nice viewpoint at Les Sources de l'Arveyron. This is a big rock with protective fencing which offers very nice views into the Chamonix valley and the mountains across and it also gives nice view into the Arveyron as it is formed at the exit of the Mer de Glace hundreds of meters above it. The crest walk over the Cote du Piget is probably my favorite in Les Bois. All in all, a very nice family and dog friendly trail at low altitude with beautiful forest and a nice viewpoint.

Risk considerations for this trail

Risk Considerations & Difficulty Assessment

This route reaches an altitude of 1274m and should be snow free from April to October at least. In winter large parts of Les Bois are reserved for cross country skiing but there are always pedestrian trails available too.  The trails are well marked and there will be trail markers for reaching the Source de l'Arveyron. One problem will be that there are so many parallel trails running through Les Bois. So making sure you are on the right one to reach the Source de l'Arveyron can be a bit tricky. The trails themselves are fairly typical for low altitude walks in Chamonix. There will be some rocky parts and a lot of tree roots but overall an easy trail.

Step by step trail directions

Trail Directions

From the Les Bois paved road and car park, make your way east till you cross the first forest trail facing north. Follow this path until it start undulating. There is a right turn here on a small mound. Take this right turn and follow this trail. It will bring you close to the Arveyron river and this is how you will know you are on the right trail. At one point the trail will bend to the left and go uphill. At the foot of this hill you will see a small side trail going to the right that has a trail marker for Les Sources de l'Arveyron. Follow this trail all the way to Les Sources. You cannot miss it. After taking a nice break to enjoy the view at Les Sources, take the same trail back. At the split take the right trail this time. This trail will take you over the crest at the Cote du Piget. You will reach a junction where it intersects with a bigger 4x4 trail. Just cross over this trail and take the smaller trail going up the crest. Keep following this and you will reach a steeper downhill which brings you to the trail that brings you back to your starting point.
