Parking is available in the centre of the village of Vernosc-lès-Annonay.
(S/E) Take Rue du Fraisse, heading west. Continue straight ahead until the road veers to the right. Ignore the direction of the road and look for the path opposite.
(1) Once on the path, stay on the main path, ignoring the neighbouring paths, until you reach the fifth three-way junction since leaving the road.
(2) Take the left-hand path downhill into the Bois de Raviney. Continue along this very rocky path (a stone shelter has been built on this path, which should be on your right as you descend) until you reach a road below.
(3) Turn left at the hairpin bend and continue along the road for 700 m. As you walk, you should see Roche Péréandre on your right, with its small observation post. Pass the only house on your right and take the first small path on the right, which leads downhill.
(4) Continue along the path to the Moulin de Cance footbridge, cross it and continue along the path, climbing steadily, until you reach a house.
Pass this house on the right before joining a wider path.
(5) Turn right and, at the next crossroads a few dozen metres further on, turn right again. Continue along this path for about one kilometre until you reach a place called Brézenaud.
(6) At the three-way junction, take the road on the right. Continue along the narrow lanes. When you reach a small crossroads with a path on your right, take the path.
Continue along this path until you reach a road at Champlat (you will cross a small footbridge along the way).
(7) Head straight ahead and, at the crossroads, turn right and continue along Chemin de Bellevue. Continue to Chemin de l'Avernée and follow this path until you reach a few houses. You are now at the LPO refuge.
(8) Cross this residential area, continuing straight ahead until you cross yet another footbridge leading to an uphill path, which in turn leads to a road.
Now on the road, continue on the path parallel to yours, located just opposite. Continue on this rocky path, which climbs steeply, and look for a small path on your right. Take it until you reach a crossroads of small paths.
(9) At the crossroads, take the path in the centre. This small path winds at first, then becomes very steep. Proceed with caution. After a good hundred metres, the path levels out. A small crossroads appears, but take the path on the left. On your right, you should see a rockfill supporting the passage of cars on the road, located a little higher up. Continue along this path until you reach the road.
(10) Turn right immediately, cross a stream and follow this road, which will only go uphill. Stay on the road until you reach the village of Vernosc-Lès-Annonay again. Stay on the road until you come to a three-way junction.
(11) Take the road on the left and follow it back to the car park where you started (S/E).
