Park in the village of Calençon.
Follow the yellow markings. Fluorescent green markings also run alongside the route up to the Col de l'Autaret.
(S/E) Hamlet of Calençon. Marker 122a. Head into the Vallon de l’Imberguet.
The path climbs steadily but steeply through an oak forest, heading south-east. Pass some ruins and a high-voltage pylon (altitude 986m). After marker 123 (altitude 1021m), the gradient eases slightly. Continue towards the small pass.
(1) Small pass of Boiéra. Continue straight ahead along the ridge. The gradient levels off slightly as you reach the Baisse de Briquet, then the climb becomes steeper again.
(2) Col de l'Autaret. Marker 448. The peaks of Roccassièra are visible; there is now a 200m climb remaining. Follow the path which climbs up to the right through the stony area (the return route will be via the path on the left).
Caution: stay on course by following the original yellow markings (the fluorescent green markings continue towards Duranus).
The climb to the ridge is steep but not vertiginous. The Roccassièra peaks are divided into several rock formations.
(3) The path descends slightly and you will need to use your hands. The trail is fairly well marked. Take the path branching off to the left, going round the rock block from below (ignore any route that goes straight over the rock blocks).
(4) Cime de Roccassièra. Climb one of the boulders again to reach the summit, where a marker and a cross indicate the altitude.
Option 1: the descent towards the Col de l’Autaret can be made via the same route as on the way up.
Option 2(the one marked on the map): continue along a lovely, easy circular route that passes through the Col de la Lobe. See description below.
For thesecond option, head towards the pass by continuing downhill due north.
The path winds through a forest and over small scree slopes. It is clearly marked on the ground. The Col de Lobe can be seen below.
(5) At the Col de Lobe (marker 449), take the path branching off to the left towards the Col Autaret.
(6) On the grassy Plat Liberte, follow the path branching off to the left, the start of which is marked by two cairns. The walk continues along a undulating path that leads to the Col de l'Autaret.
(2) Follow the same route as on the way out, passing via Collet Boièra, to return to the starting point (S/E).
