The itinerary begins gently, taking in the Nordic ski trails before heading deep into the forest and beginning the ascent to Lake Achard.

? Warning: the Arselle plateau is a protected area (peat bog classified APPB - Arrêtés Préfectoraux de Protection Biotope), so there are a few rules to observe to help protect it. Fires, wild camping, picking and dumping waste are strictly forbidden, and bivouacs are prohibited during the peak season between early May and late October. Please stay on the path that circles the area, as it is forbidden to go onto the plateau in order to preserve the fragile environment.

? The little extra: the "hiking star" summer medal for children!
On presentation of a photo taken at the hiking site, brave little hikers will be awarded a named diploma + possible purchase of the "lac Achard" silver star to hang proudly on the backpack (on sale for €3 at Tourist Offices).
