Park in Saint-Dionisy, in the car park running alongside the D40a (Nîmes road) at the corner of Rue du Chêne Vert.
(S/E) Head towards the village centre. Take Rue du Vieil Four. Then take Rue Bécagrun and continue along Chemin Roque de Viou, which runs behind the cemetery. At the first junction, turn left and follow the path as it climbs.
(1) At the top, you’ll come to a junction of several paths and tracks. Take the one furthest to the right, which passes the elevation markers 145 and, further on, marker 18; follow the cliff-top path with views to the north, then to the west.
At the left-hand bend, visit the remains of the Roque de Viou oppidum. The path now curves southwards and eastwards.
Avoid any paths that lead back down.
(2) Walk past a beautiful drystone shelter on your left and continue until you come face to face with the ruins of the oppidum.
(3) Continue due east along the path that runs alongside the northern wall of the buildings. The path now descends rapidly to the source of the Ranquet. You are now in the village of Nages. Take Rue de la Fontaine Romaine, then turn left into Rue de l’Oppidum. Cross the L’Agau stream.
Walk along the esplanade to the north and head back up via the Chemin des Aires. At the fork, turn left under the pine trees and walk along the wall of a large property.
(4) At the 136-metre elevation point, turn right into the pine forest. At the crossroads where four paths meet, head straight ahead. 150 metres further on, you’ll come to the Chemin des Lauzières, which you take to the right.
(5) Walk south past the sports grounds and turn left onto a path that runs alongside the tennis courts, heading due north. Then turn right, moving away from the sports facilities whilst staying on the higher ground.
(6) At a place called Le Cabanis, turn right, staying on the plateau. You’ll soon reach a path leading to some houses; turn left onto the Chemin des Lauzières. At the junction with the Route de Nages (D137), turn left onto the Chemin du Coin du Loup, which you leave 150 metres further on, continuing to the right along a small path that takes you to the Moulin à Vent esplanade.
(7) Head back down onto the Chemin du Moulin à Vent and continue to the chapel.
(8) Turn left onto a path that winds along a ledge overlooking Langlade and descends to join the Rue de la Calade. Turn left into the Rue Haute, then, a few metres further on, turn right. Then turn left into the Rue des Lavandières.
(9) After the washhouse, take a path on the left. It turns into a track and climbs through the vegetation. At the first three-way junction, turn right. Continue along the hillside until you reach the sports grounds, which you’ll recognise by the pylons.
(10) Walk along the northern edge of the sports ground and head back up the path on your right.
(11) Pass the Castellas site (altitude 164), then head down the second path on the left, which follows the contour lines back to the crossroads (altitude 145), completing a circular route.
(1) All that remains is to head back down the path you took on the way out, which will take you back to Saint-Dionisy (S/E).
