Park in the car park at the edge of the hamlet of Prats Haut, on the way towards Molines-en-Queyras.
(S/E) Walk through the hamlet and turn right onto the wide Pré Claous track. Leave this track to the right and set off along the footpath. You’ll reach the banks of the Grand Rif stream.
(1) Continue along the right bank of the stream, keeping a short distance from it. You’ll reach a crossroads of paths at the water catchment area, which is protected by a fence.
(2) Cross the stream, rejoin a wider track, then leave it to the left to head off-track into the larch forest. Further up, rejoin the path; follow it to the left to emerge at the edge of the woods. A few metres further on, you’ll find the Cabane de Peyrallas.
(3) Start the descent to the right into the mountain pasture, running parallel to the edge of the woodland. Cross the area known as Pra Comtal. Further on, reach the track for the Canal de Pierre Dimanche.
(4) Cross this track, continue straight down the slope and reach the road linking Prats Haut to Molines. Turn right onto this road to return to the starting car park (S/E).
