Step by step description : From the Murianette hiking sign (alt. 223 m), take the road towards the hamlet of Murianette, the "Montée du champ de la vigne", following the yellow markers. Pass the Mairie (town hall) and continue straight ahead, before turning left towards La Tour on the "Chemin de l'Église", above a large bourgeois house. Still on the road, take the "montée de la Tour", and at the first hairpin bend, continue straight ahead to leave the asphalt. Go up the track to reach, on your left, a gully as far as the Roujard fork (alt. 405 m), where you continue to climb to the right towards La Pérérée. Slightly higher up, the path crosses over the Rivet stream to its right bank. After a steep stretch of track, just before reaching the road, you come to the Les Charmettes intersection (alt. 510 m). Take the track to the right towards Les Combes. This descends a little to cross the left bank of the Rivet stream again, and reach the road. Turn left for 20 m to reach Les Combes (alt. 511 m). Take the road to the right, the "chemin de Combeloup", towards the Combeloup forest (2.52 km). Continue on the asphalt to its terminus at the Combeloup farm, with the Venon oak in view. The road becomes a track again and, above the meadows, reaches a fork where you continue to the left, still heading for the Combeloup and Pressembois forest. In the forest, you go around a first combe to reach a ridge. The path then descends to the right. After crossing several streams, you come to the wide crossroads of the Combeloup forest (alt. 672 m). Turn right towards Pressembois. Keep going straight downhill until you reach the Route de Venon, which you follow to the left for 100 m to reach Pressembois. At the signpost, turn right onto the path leading to Champ Duret, 2.2 km away. After a good descent and a slightly uphill crossing, you emerge from the forest. Turn right towards Murianette. The trail crosses back again, this time heading north. Follow it and, as it begins to climb again, turn left onto a narrower path. A steeper section brings you back to the first houses and the Pisse-Vieille stream. Below the flood barrier, turn right up the right bank of the stream to continue towards the hamlet of Murianette. At the road, continue on the opposite side of the road, then, at the Tarrin crossroads (alt. 300 m), turn left to descend to Murianette village and, back on the road, return to your starting point.
