From the salle hors-sac / foyer de ski de fond, take the wide trail down past the restaurant de la Salinière. Leave the track and turn left onto a narrow path that runs along the edge of the forest and alongside the peat bog.
Continue south towards the Plateau de l'Arselle. An incursion into an area of meadowland offers a magnificent panorama of the neighbouring Taillefer massif.
After a short climb, a wider path leads you to the "La Lanse" signpost. Leave the path leading up to Lac Achard on your right, and turn left onto a track that takes you back to the starting point (Plateau de l'Arselle post).

The wetland is a sensitive area, so make sure you stay on the paths and don't cut across any small paths in the peat bog.

? Warning: the plateau de l'Arselle 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, bivouacs, picking and dumping waste are strictly forbidden. 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.
