Refine your search for walks in Bonheur (rivière) - Affluent du Trévezel
The Chemin des Morts de Saint Sauveur Camprieu

Despite its uninviting name, this is a superb hike under the forest canopy. The name comes from the fact that there was once no cemetery in Camprieu, forcing the inhabitants to carry their dead to the hamlet of Saint-Sauveur.
Sporty loop around the Aigoual

For experienced hikers, here is a 40 km loop starting from Valleraugue and reaching Aigoual via the famous 4,000 steps. It descends to Lac du Bonheur near Camprieu, then climbs back up to Espérou and ends along the ridges facing Mont Aigoual, which you will have discovered a few hours earlier.
This hike is not technically difficult but is very long with some steep sections and requires good stamina.
