Access: Car park at the entrance of the service road to the new settling basins.
(1) From the car park, take the wide, stony track. Walk 300m down the track until you reach a crossing, just before the buildings for the settling basins.
GR4F: Red and White Waymarks
(2) Take the GR4F trail on the right and follow it for about 2.6 km. The path climbs up to Gras plain, where you have views of the Cirque d'Estre, and then continues back down. At the crossing for Combe Longue, take the path to your left and carry on to the next crossing at Bois du Roi.

(3) Leave the GR4F trail and take the path that climbs up to your left.
(4) At the following crossing on the plateau, take the path on your right towards Caverne du Pont d'Arc and follow it as far as the crossing at Serre de la Desferre.
(5) Take the path on the left towards Vallon-Pont-D'arc and follow the stony path as it winds down the hillside.
(6) You will come out onto a track. Turn right and take the leftmost of the two paths ahead of you. Go along the D4 road for 250m, then take the path off to the left, and you will come to a fork.
(7) Take the right-hand path, which takes you down to the bottom of the valley. Cut across the D4 road and follow the path, which then joins the road again below. Follow the road round to the right, cross the bridge, and take the turning to the left on the other side of the bridge.
(8) At the sign for "Pont sur l’Ibie" follow the path on the left down to the riverbed and walk along the river bank for 800m. The path then begins to climb again and ends in a fork. Take the left-hand path, which then joins the GR4F trail at a small submersible bridge.
