Park in the Tourist Office car park at the entrance to the village of Trigance.
(S/E) Walk up the street that passes in front of the wash house and Rue du Four to the small square where you will find a bakery and a snack bar. Go around the fountain and turn left up Rue du Puits. Cross the tarmac road and take the path opposite, marked with signs for GR®49 (red/white) and PR® (yellow). Then continue to the junction where the GR® and PR® paths separate.
(1) Turn left to stay on the GR® and reach a crossroads marked by a sign.
(2) Take the path on the left, pass under the Serrière du Preil ridge before crossing the one connecting the Sommet de Breis and the Cime de Biach. Continue slightly uphill until you reach the hamlet of Entreverges.
(3) Go around it to the east, following the path that branches off to the right, still following the double GR®49 / PR® Yellow markings, then join the PR® fork.
(4) Keep left on the GR®, down a fairly steep descent, and you will soon come to another fork.
(5) Leave the GR® here and take the path on the left. Begin the climb westwards to the Rancoumas viewpoint.
(6) Return in the opposite direction to the PR® fork.
(4) Leave the GR® and head opposite onto the yellow-marked PR®. Continue uphill for about a hundred metres, then begin the descent, which is easy and mostly on open terrain. Follow the path along the edge of the ridge to reach Casseyères.
(7) Turn right, then continue downhill via a hairpin bend to the right to return to the initial crossroads you passed on the way up.
(1) Retrace your steps to return to the Trigance car park (S/E).
