At Pallon, take the road to Freissinières and continue along this road to the Dormillouse car park.
(S/E) Take the path at the back of the car park (signposted), cross the bridge and begin the pleasant climb to the hilltop village of Dormillouse.
You will reach a trail junction.
(1) Take the left-hand path, leaving the right-hand path which leads to the village of Dormillouse. Stay on the left-hand path, ignoring all the paths you come across. You will reach the edge of the forest and come to another crossroads.
(2) Turn right and head for the Palluel hut in the mountain pasture.
(3) Continue climbing to reach Lac Palluel.
(4) Then take a vague path on the right that leads to a pass, then continue to the right to reach the Tête des Arrindoux.
(5) Take the same path back to Lac Palluel.
(4) Take the balcony path to Lac Faravel. There are no specific markings on this path, but there are cairns along the entire route.
(6) Take the path on the left, which leads down a long descent followed by a cross-country link to a fork.
(7) Turn right and follow another descent to reach the lake crossroads.
(2) Retrace your steps in the opposite direction to the car park (S/E).

Well done to you anyway, it must have been a real treat.
