half day
Departure point: Plateau de l'Arselle reception hall - Chamrousse 1600.
Before you start your walk, take a moment to stop and enjoy the scenery.
For the round trip, allow 2h45 (5.4km).
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 €2.50 at Tourist Offices).
Pets allowed only during summer: dogs are allowed on all trails on a leash (please avoid taking them to the Arselle plateau, which is a sensitive natural area). The shepherd who works in Chamrousse in the summer has no Pyrenean Mountain Dog.
Opening periodFrom 07/06 to 01/10.
