Very varied hike in the national forest then on the ridge. This walk allows you to discover the Vallon de l'Estang and beautiful panoramas over the Rosans basin. Discover the toponymic path (study of place-names) of the Regional Natural Park of Baronnies Provençales.
From the village square, go up along the small road to the right of the Church in the direction of Lastic by the GR 91. After Lastic, the road gives way to a track suitable for vehicles. Follow it for 2 km to l’Estang (1st observation point of the toponymic path). Pass the locality while remaining on the track and enter a pine plantation. A few tens of meters further, find an old path to the right of the track, at the level of a bench, and leave the GR markings for the PR markings.
Follow this path, along the hillside of the Estang valley (stream below). Cross the stream and go up to come out on a track. Follow this track to the right for 1 km (2nd observation point of the toponymic path).
In a sharp curve, take a path that goes to the right and plunges onto the crest of Serre de l'Aigle. At a boundary marker of the PNR des Baronnies Provençales (3rd observation point), turn right and walk along a fence for 700 m. Continue down hill, the path bends to the left and reaches large limestone slabs. Some traces of fossils can be observed.
Go down the slabs and find a path on the right which leads to a track. Continue on it. At the crossroads, turn right, and again to the right in a sharp curve, At the tarred path, turn left and descend it. Continue to the village center, along the kindergarten.
