Park at the entrance to the village, cross the suspension bridge and immediately turn right downhill.
(S/E) With your back to the Auberge la Valette, turn right towards Faveyrolles on the D60 and follow this road for about 1 km.
(1) In a left-hand bend, take the path on the right, which offers a beautiful view of the village. Continue along the path that climbs towards the ridges and leave the path that descends towards the village on your right.
(2) At the next crossroads, take the second path on the left, then turn left again about 200 metres further on and you will come to a fork.
(3) Continue to the right, then at the next fork, follow the left branch. Leave Mas d'Hermet on your left and reach the abandoned farm of Graudenc.
(4) Leave the path on the left, continue straight ahead and cross through some undergrowth. Ignore the paths on either side, pass under a high-voltage power line and descend towards the Gos valley. There are some beautiful views of the three valleys.
(5) At the crossroads, leave the track and take a path on the left that descends into the field to the undergrowth. Continue downhill following the track, passing in front of Vacayrial. Continue downhill, ignoring all the paths on the right.
(6) At the second hairpin bend, continue to the right towards the sandpit and the banks of the Tarn. Follow the shady left bank.
(7) Turn right towards Les Alvernhes. In the hamlet, turn left onto the road and follow it, continuing along the riverbank. About a hundred metres before the old railway line, which is now the D200, leave the road, take a path on the left and head for the bridge.
(8) Please note that the markings are not very visible. Pass under an arch of the bridge and turn completely right. Follow a small path that runs alongside the Dourdou and allows you to bypass the tunnel by passing through a place called Janolles (a pretty 16th-century building).
(9) At Janolles, follow the path southwards. The section along the riverbank has been slightly damaged by the recent flooding of the Dourdou, but the trail is still visible: walk on the pebbles and then follow the path again. Continue along the access road to Mas de Gascuel.
(10) Turn right to go around the farm and follow the markings. Turn left quickly and go around Mas de Gascuel, leaving the buildings on your left. Continue straight ahead, pass under a power line and reach a farm.
(11) At the farm, continue straight ahead to reach the small road that leads back to Saint-Izaire, passing through Mazet. Leave the Mas de Nègre path on your left.
(12) In the village, you can continue straight ahead to return directly to the starting point via Rue de l'Ecole and then Rue des Fosses, or turn right to visit the castle and walk around the village (option shown on the map). (S/E).
