The start is at the Pont de la Serre car park, accessible via a poorly maintained ONF track, approximately 7.5 km long, starting from Colmars-les-Alpes.
(S/E) From the car park, follow the closed track for about 1 km to La Lance.
(1) Take the track on the left which crosses the stream via a wooden bridge; note the chalets at the hamlet known as Pont de la Serre on the left: the track straight ahead is the return route.
(2) Ignore the path on the right leading to the Cabane de la Fuchière and continue along the track, following two hairpin bends.
(3) Follow the PR® sign by turning right. Pass the Juges shepherds’ hut on your right and rejoin the track further up.
(4) Continue to the right, climbing up a well-marked path through the valley enclosed by the Sommet de la Môle: admire a beautiful waterfall on your right.
(5) Pass the Cabane de Bressenge on your left and head straight on, climbing up the ravine of the same name.
(6) Tackle the steeper climb on the left, following large cairns, and reach the plateau.
(7) Cross the plateau along a lovely path marked by large cairns. You can also stray from the path to wander across the plateau without any risk of getting lost. A virtually flat, grassy plateau with large rocky outcrops. Reach the first Lac de Lignin.
(8) Go round it on the left and reach a junction just before the Cabane Pastorale de Lignin.
(9) Turn left and head for the second, smaller lake. Then head right to pass close to the other lakes, following the small ridge and keeping to the edge of the plateau to rejoin the path leading down.
(10) Turn left and begin the descent.
(11) Head to the right to rejoin the signposted path as it approaches the edge of the valley. From time to time, you’ll catch a glimpse on the right of the ascent path at the bottom of the valley and the numerous shepherds’ huts seen on the way up.
(12) Pass close to the Cabanes de Mouriès, continue along the edge of the valley, then descend more steeply as you approach La Lance.
(13) Carry on alongside the stream: here you can admire numerous pools, some of which are accessible for a swim depending on the time of year, or for a photo. Return to the junction you passed on the way out.
(1) Carry on straight ahead to return to the Pont de la Serre car park (S/E).
