Road access: In Caylus, head towards Saint-Antonin-Noble-Val on the D19 and stay on this road at the bottom of the valley. At the 4th road on the left, head towards Château de Cas, then take the 1st road on the right, continue and park in the bend below the château.
(S/E) Retrace your steps along the road for about 150 metres and take a path downhill on your left. Follow it over a bridge and then to the foot of the Barry de Cas mill (with a magnificent rose bush).
(1) Turn right onto the D19 road for 100 metres, then take the road that goes up on the left (towards Saint-Amans). Just before the first bend, you will see a wash house at the bottom of the valley on your right. Then, on the next straight stretch, enjoy the view of Château de Cas. In the left-hand bend, take the path on the right and follow it until you reach Rocher Tremblant.
(2) Continue along the path that passes under some houses before reaching a small road, turn right and pass in front of the quarry. Continue along this road until you reach the intersection with theGR®46(white and red markings).
(3) Leave the road and turn right. At the next junction, turn right and then left about 50 metres further on (you will see a beautiful low wall on your right) to return to the church of Saint-Amans le Vieux (private property). Continue on theGR® which runs alongside the church on your left. At the crossroads with a cross, continue on your right.
(4) Continue straight ahead on the path and, at the next intersection, turn right to make a round trip to the restored bread oven, which is about a hundred metres away.
Retrace your steps.
(4) Turn left onto the path that descends into the valley. Follow it until you reach a place called Bon Repos and continue straight on to the D19. Turn right onto the road and follow it for about 150 metres.
(5) Turn left onto a small bridge to cross the Bonnette and pass in front of a house in the hamlet of Larché. The path continues along the edge of the field (small wooden gate with a chain to close behind you), passes along the edge of the pastures and then through the forest before arriving at a small road (D20). Turn right onto the road, then quickly left.
(6) At the bridge over the Ruisseau de Rigail, turn right and follow this quiet road between the pasture and La Bonnette. At the next intersection, turn right, pass in front of the farm and then over the small bridge over the Ruisseau de Caudesaygues. A little further on, on your right, you can see the lock that feeds the Moulin du Gal canal.
(7) Pass in front of the mill, then at the next bend, take the path on your left. After 50 metres, turn right and continue straight ahead until you reach a small road. At the next intersection, continue straight ahead to your starting point (S/E).
. On the road after the bridge (D20), it says to turn right without any further details, even though there is a sign with a cycle route to the mill. Our hike ended well thanks to a very nice motorist who gave us a lift back to the Château de Cas.
