The starting point is at the end of the Vif bypass, at the start of Route de Reymure, just before the underpass beneath the A51 motorway: parking available.
(S/E) Go under the motorway bridge then turn right onto Route de la Santon.
(1) After about 500 m, turn right onto a path that runs between farmland (yellow markings). Continue along this path as it climbs into the forest, following the markings for about 1.5 km.
(2) Leave the marked path and follow a track to the right which heads north and climbs steeply. Before reaching the summit, the view opens up onto the Isles du Drac.
(3) Pass the summit of Petit Brion and begin the descent along a well-marked path.
(4) Continue the descent by turning right and rejoin the A-road. Cross it carefully and take Rue de la Merlatière opposite.
(5) After about a hundred metres, follow the path on the left which climbs steeply, passing under the motorway viaduct.
(6) Turn right onto a good track and continue further along the tarmac road until you reach a junction.
(7) Turn right and follow the road downhill until you pass under the second motorway viaduct. Turn sharply right and head back up the other side of the A51: the road becomes a track and leads to the Plateau du Crozet.
(8) Take the first left. 100 m further on, follow the most obvious path to the right, and 100 m further on, take a path on the left that follows a fence and continues downhill. This path enters the woods, crosses a bridge over the railway line and leads onto Rue du Bois du Gua.
(9) Turn sharp right, follow the street until you reach a ‘private property’ sign. Take a small path on the right with a few steps that leads back up to the level of the railway line. Follow this path, which leads onto Rue de la Merlatière, and turn left.
(5) Continue straight on until you reach the traffic lights. Walk along the left-hand side of Avenue de la Gare, cross at the pedestrian crossing to enter Rue du Truchet opposite and follow it.
(10) Turn right, pass the police station, and continue straight on until you reach the starting point (S/E).
