To get to the start, follow the D330 between La Paillette and Vesc. Turn off onto the first small road on the right (just before a bridge). Follow this road for 3 km and, at the end of the tarmac, park near the DFCI water tank.
Be careful not to obstruct the fire service by parking between the road and thefire hydrant.
(S/E) Continue along the track that extends from the road. Pass a turn-off on the left and continue until you cross a small stream at a left-hand bend.
(1) Leave the track and take the forest path climbing opposite. At the top of the climb, turn left and continue climbing to the ridge (not shown on the IGN map).
(2) At the ridge, turn right and follow the path until you reach the forest track.
(3) Continue climbing and at the next two forks to the right (not marked on the IGN map), go straight ahead. The path curves to the right and the slope becomes gentler. Go through a hairpin bend to the left and then one to the right. A few metres further on, leave the path on the left and you will soon reach a fork in the path.
(4) Walk about ten metres to the left to the end of the path. Find a barely visible trail that veers to the right. Follow it as it turns right into the undergrowth a few metres from the edge of the forest, then turns left and exits the woods.
Climb this small path, which almost disappears in places in the heath, to the summit of Bec de Jus, following the top of the shoulder.
(5) After enjoying the view, descend via the same route and return to the DFCI water tank (S/E).
