(S/E) From the Valladas car park, go up Rue de la Poste and join Rue de la Poterne.
Cross the centre of old Châteauneuf and join Rue du Portail. Follow the Sentier Botanique uphill to the statue of the Virgin Mary.
(1) Turn right onto a wide track that runs alongside the ramparts of the old castle. Magnificent view over the whole village. Continue along this track, which is shared withthe GR®, for over a kilometre, then leave it when it turns left and follow a path straight ahead.
(2) At the intersection, turn right onto the path. Follow it, ignoring the paths on the left. Splendid view of the Rhône. On the way back from this circular balcony, keep to the right and rejoin the section taken on the way out.
(2) This time, turn right onto a small grassy path that runs alongside a meadow. Join an old BMX track.
(3) Keep left and rejoin the main path, which further on turns south and runs alongside the Donzère road.
(4) At the end of the path, cross the road and take Chemin de Belle Eau. In the bend in the road, keep left and continue until you reach the gate of the house.
(5) Then turn right onto the stone and dirt path that climbs up the slopes of Navon.
Take the forest track on the left to climb up and, near the top, take the small path that climbs up to the ridge on the left. Splendid view of the Rhône valley and the mountains of Allan and Malataverne. Descend the ridge, continuing in the same direction.
(6) Turn right onto a path under coniferous trees. Join the forest track and follow it to the left. Just before the first house, take the grassy path on the left which joins the Chemin de Rac aux Joannins, then turn left.
(7) At the hairpin bend with Chemin du Navon, you can make a round trip to the hamlet of Rac. Otherwise, turn left onto Chemin du Navon. Stay on this small road for about 2 kilometres.
(8) Turn right onto a small path that descends. This leads to the ruins of Châteauneuf and joins Chemin du Cimetière, which takes you back to the starting point (S/E).
