Park on the grass verge near the Pont de Costet bridge, immediately to the left of the bridge when leaving Langeac towards Clermont-Ferrand. You can also park in the restaurant car park on the left bank.
(S/E) Head towards the Allier and follow the road that runs alongside the river to a three-way junction where there is a beautiful tree flanked by stone benches.
(1) Turn right and climb towards Le Cros.
(2) At the top of a gentle slope, turn left, leaving the access road to the main road on your right. Descend towards Truchon and reach the centre of the village, where you will find the Maison de la Béate, named after the head nun, Béate, who taught, prayed, cared for and provided other services to the community.
(3) Pass in front of the house and a water basin on your right, then take the road that curves right uphill towards Le Fournet and the water treatment plant.
(4) Leave the return path on your left and continue straight ahead. Pass a small ruined house.
(5) Turn right onto a path that climbs very slightly up the Graulet ridge and leads to a crossroads with several paths offering a beautiful view of the volcanic cliffs of Biot opposite.
(6) Take the wide path that descends to the left towards Le Chambon.
(7) At the intersection, you can first turn left then right to visit the village of Chambon, its bridge, beach and cliffs (this detour is not included in the route). Otherwise, turn left onto a wide track that runs alongside the Allier river and returns to Truchon.
(5) Continue straight ahead, passing the hut on your right.
(4) Turn right to get closer to the banks of the Allier and reach Truchon. Pass the basin and the Béate house again.
(3) Continue until you find a zigzag passage on the right between the houses, which leads to a path downhill towards the Allier, which is very wide at this point. This leads to a tarmac road.
(8) Follow it to the right to walk along the river.
(1) Continue along the Allier to return to the car park (S/E).
