Park in the designated spaces on Route de Cize. Other parking is available near the church.
(S/E) Head towards the church, then turn left onto Chemin de la Croix Peyrousse, towards the hamlet of Soiriat. At the crossroads, turn left, then right to follow Chemin sous la Roche.
(1) Take the track on the left, then go up the small path. Cross two cattle grids.
(2) Just after the second one, turn right to follow a narrow path, which is visible in places and occasionally marked with yellow signs. The climb alternates between woodland and very open sections. When you reach a T-junction, turn left and start a steep climb.
(3) Cross the road carefully and continue climbing through the forest. The path is much better marked. Walk slowly through the undergrowth until you reach the summit of Mont Rosset.
(4) Turn right onto a forest path that leads to the small plateau at the top of Mont Rosset. Reach the summit of Mont Rosset, where cows graze (in season). Ideally, take the short path on the left to pass the gate without dismantling it.
(5) Turn left: there are no markings as the area is bare, but you will see two small cairns indicating the direction. Enter the small forest and continue until you reach the cave.
(6) This is where you will explore and find 10 information panels, located vertically in the different rooms of the cave. There are some explanations about the formation, exploration and fauna. Then descend along a barbed wire fence on the left to discover the entrance to the cave, which is closed, and the last information panel. Continue along the trail, heading south, and return to the road you crossed earlier. Follow it, turning right, for about 250 m.
(7) Turn left onto a shaded path and return to the double cattle grid you crossed on the way there.
(2) Continue straight ahead and retrace your steps to return to Soiriat.
(1) Turn right, then left to follow Chemin du Lavoir (a pretty wash house, by the way), then turn right and left to take Chemin de la Messe, which leads to Route de Cize.
(8) Turn right and continue straight ahead to arrive at the church and the car park (S/E).
