Coming from Gap towards Ancelle on the D13, 2.6 km after the roundabout, park in the bend on the left (space for two cars).
(S/E) Retrace your steps for about fifty metres to the start of the walk.
Turn right onto the Route du Puy de Manse path and follow it for 250 m until you reach the sign for Puy de Manse 2.4 km.
(1) Turn left. Follow the path for about 600 m until you reach the next sign.
(2) Turn right and follow this newly marked path to its end, reaching the summit of Puy de Manse – marked by a cross (elevation 1637) – whilst keeping the fence on your left.
At the summit, there is a viewing platform, pending the installation of an orientation board.
(3) The walk continues across the pastures of the Montagne du Puy, heading due south.
(4) At around 1,505 m, continue down the steep slope, keeping to the right towards the hamlet of Manse Vieille (1,289 m). This is the least pleasant part of the walk. When you reach the road, continue along it to the right.
(5) In the hamlet, at the first bend to the left, take the path on the right which leads to a spring catchment (elevation 1302).
(6) A few metres before the wire fence, take the path that climbs to the right. From there, follow this path back to the original crossroads.
(1) Return to the car park via the same route (S/E).
Editor’s note added on 12/09/2021: there is an issue in the second half of the walk; a round trip seems preferable: see the comments at the bottom of the page
