Park on the right-hand side of the D31 towards Le Jolan, just outside the village of Fortuniès, at the edge of a track marked "Lac du Pêcher"
(S/E). After the metal barrier to the left of the farm buildings, take the pleasant path towards Lac du Pêcher.
(1) After a while, turn right for a round trip to the bird watching site (original architecture), near the Chantelouve stream. Then retrace your steps, and through a metal barrier, join the tarmac road, then walk along the left bank of Lac du Pêcher for a few hundred metres.
(2) Just before the dyke, take a path on your left to enter the forest. Pass by the foot of an imposing deer observation post. Shortly afterwards, turn right and go down the path to cross the Ruisseau de Fons Nostre. After crossing the tarmac road, take a new path at the Font des Chazeaux (watering hole). Walk through the forest for a while (avoid the detour through the village of La Boissonnière) until you cross the D23 again. Follow it to the right until you reach a car park on the other side of the road. At the far end of the car park, on the right, take a path up to the Roche du Pic
(3). From Roche du Pic and its orientation marker (where I encountered the wolf in winter 2017), follow a path downhill. At the crossroads below, take the path on the right to rejoin the D23 road, near Lac Grand (bog). Follow this road for about two kilometres, then leave it at a new car park on the left-hand side of the road, with a hunters' hut From this car park, take the "Chemin du Frau" opposite. After a short stretch through the woods, you will come to a wide, very long track, which you should take on the left.
(4) This will take you to the edge of the woods, to the peat bogs and Lac du Frau de Collanges.
(5) Just before you reach the lake, take a wide track on the left, which will take you to the dyke in a very unspoilt area. Take advantage of this break to enjoy your snack and let yourself be lulled by the magic of the place. Return to the junction with the main track, at the edge of the lake, and continue for a few more metres before a crossroads on the right.
(6) This new 4x4 track descends towards the Santoire valley. Leave it quickly as soon as you see the Péjouzou farms on your right . Go through a barbed wire fence and follow a very rough path through the meadows to find a tarmac road in front of the farm. This will take you uphill to the Sauvages farm and then to the lake's dyke.
(7) Then pass in front of the lake refreshment bar and quickly turn right onto a path that is tarmacked at the start. This path starts to the left of large metal gates and then crosses meadows, but it is very poorly marked at the start. It becomes clearer as you climb a little higher. You will need to cross two fences in succession. The village of Fortuniès will be visible as soon as you pass the second fence. This small path will lead you downhill to the junction with the D23 at the entrance to Fortuniès (S/E).
