Road access: In Saint-Antonin-Noble-Val, park in the car park on Avenue de la Gare, on the banks of the Aveyron and under the plane trees.
(S/E) Continue to the end of the car park, then take the small road on the right, which then becomes a track and follows the Aveyron. Stay on this track. On your left, you will find the source of Poulso Guerro.
(1) Continue along the track until you reach a first intersection with a house. Continue straight ahead along the Aveyron until you reach a field.
(2) Continue until you reach the road (D115). Follow this road to the right, cross the bridge and, just before the tunnel, take the track on the right.
(3) Leave the track and take the path that starts with steps on your left. The climb begins. The path zigzags upwards with steps. You will then arrive at the foot of the cliff. A steeper and more difficult section begins, where the ground can be slippery (there are cables to help you), ending when you see the "OUF" sign. Remember to turn around from time to time to enjoy the view.
The well-marked trail follows the side of the cirque, revealing the Aveyron, its mills and the Roc d'Anglars. There are intersections that lead back up to the Cirque de Bône car park and its information board (small sign with a "Y").
Red markings
(4) Keep to the path on the hillside, which will begin to zigzag downhill through a limestone landscape. At one point, you will enter an area of boxwood and moss. Leave the path and follow a small stream on your right for 3 metres to reach a natural water hole in the rock and a small gariotte (stone hut) just above it on your right.
(5) Return to the trail, pass a watering hole and continue along the trail until you reach a clearly marked intersection.
End of the signposts
(6) Take the path downhill on the right. When you reach the banks of the Aveyron, continue along the path on the left and follow the river. Take the road that climbs up in front of you and, at the next intersection, take the road to the right.
Pass the Maladrerie, the former leper colony, then the old lime kilns (cliffs carved out on the left).
(7). Continue straight ahead and enter Saint-Antonin. Continue to the small bridge over the Bonnette and cross it.
(8) Turn right and follow the road on the pavement. Cross the bridge over the Aveyron river, then turn right to reach the car park (S/E).
