Coming from Saint-Privat, the car park is on the right-hand side of the D259, at the end of the Échelette climb.
(S/E) Leave the car park via the south-west corner using a slightly steep staircase. Pass two paths on your right and take a path on your left heading south-west.
At the three-way junction, turn right, pass a path on the right and then another on the left, and continue to the crossroads after the right-hand bend.
(1) Continue along the path on the right, passing an information post and arriving at a sign indicating the oppidum.
(2) At this point, a triangular area has been cleared to highlight the rampart. Take the path on the left and continue along the rampart to the first viewpoint above the cliff.
(3) Walk to the northern end of the small plateau, following the row of large stone blocks. Turn right, then immediately left onto a path heading north.
Continue along this path, which approaches the cliff in several places and then begins to descend the ridge.
(4) At a pile of stones, possibly a collapsed wall, take the path on the right. Continue downhill and join a path that climbs up from the valley.
Take this path on the right to climb back up to the rampart site.
(5) Before reaching the deforested area, look for the remains of a round tower. Take the path that crosses this tower, then turn left to follow the inside of the rampart.
At the end of the rampart, just before reaching the top of the cliff, keep left to pass through the main entrance gate with its chicane wall.
After the gate, head right again towards the cliff, then turn left onto the path that starts between the second and third blocks of stone. Follow this path until you reach a Y-shaped fork.
(6) Turn right. About 50 metres further on, you will come to an area of rubble. These are the remains of the north wall of the "Camp de César" enclosure. Take the path on the right that follows this wall.
(7) You will come to an open area offering a new view of the Ardèche on the south side towards Saint-Sernin and Mont Vinobre. Head back almost in the opposite direction, taking the wide path on the left that passes over the highest point of the hill. Continue along this path, cross the Camp de César enclosure again and descend towards the bottom of the valley.
At the first fork after the descent, turn left. Continue north and take the first path on the right to return to the junction of the circular.
(1) Follow the path to the right along the route you took on the way up and return to the car park (S/E).
