You can return to the starting point by taking the D92 between Gissac and Lapeyre. When you can see the pylon by the side of the road, two paths lead off from the same point. Stop there on the grass.
(S/E) Take the path running perpendicular to the road and head down towards the west. Ignore the path branching off to the left and continue to the right.
(1) When you see Mas Raynal (a farm), turn right, heading north, onto the path that climbs between two hedges. Walk straight up the gentle, steady slope until you reach a multi-way junction.
(2) At this junction, take a moment to enjoy the view, then take the path that winds sharply to the right.
(3) Follow the path on the right up to the foot of the Puech de Mouray pylon for a quick look around. Then head back down to continue along the path and rejoin the D92.
Once on the D92, walk 30 metres to the right to return to your car (S/E).
