From Serres, take the D1075 then the D994 towards Veynes. Turn right halfway along the D49 and drive to Saix to start the walk at the church.
(S) In the village of Saix, opposite the church, head down to the left along the Chemin de la Péguière to reach the footbridge spanning the Torrent de Maraize.
(1) Continue uphill to reach the Col de la Combe Escure. The climb is a little steep but only for a short distance. PR®® signposting.
(2) Continue to the Col de Tré Maroua.
(3) Make your way along the marl ruts on a wider path through the forest. Go past the pass to reach a tricky, narrow passage through the marl near the Torrent du Cheynet.
(4) Carry on and you will then emerge into a meadow. Keep to the right-hand side of the meadow to reach a lane lined with trees and dry stone walls, which leads towards the old village of La Péguière.
(5) Turn left towards Clausonne Abbey. Follow the cairns and yellow markings. The path turns into a track. Once on the track, take the first path on the left to reach the abbey site.
(6) Continue to the right to cross the Torrent de la Péguière and join the forest track. Turn right and head uphill to Lac de Peyssier, continuing straight on at every junction (GR® markings from thefirst junction).
(7) Walk along the lake and, at the very end, after crossing the Torrent de Maraize once, leave the GR® on the plain and take a path keeping to the right which crosses the Peyssier plain. At the ‘Les Oustaus’ signpost, turn right to reach the Lodge des Oustaus. (E)
