Starting from the Refuge de Vens.
(S) From the rear of the refuge, head towards the Collet de Tortisse, climbing to the right of the waterfall. Cross a stream and then follow the red and white markings. Climb the wide hairpin bends at a leisurely pace.
(1) You’ll reach the Collet de Tortisse (altitude 2,591), marked by signpost 35a; continue straight along the path, keeping to the flat section towards the Col du Fer.
(2) You’ll reach the Col du Fer (2,584 metres) at marker 35. This is where theGR® (red and white) markings end. Take the path on the left, beginning the ascent to the summit towards the Pas de Morgon (the peak marking the border between France and Italy). Follow the path and the cairns, taking care on the steep slopes on either side where there are significant drops. The path remains wide and easy to walk on for most of the route.
(3) Cross the area of large boulders and rocks, keeping to the left and following the cairns closely. Continue towards the Pas de Morgon until you reach it.
(4) Pas de Morgon (2,714 metres), the highest point of the hike and the end of the ascent. Begin the descent by continuing along the path towards the Lacs de Morgon.
(5) Turn off onto the path on the left towards the Morgon Lakes and follow the cairns down the slope.
(6) Walk along the left-hand side of the Morgon Lakes, following the cairns, and continue to the Lac Majeur de Morgon (elevation 2338).
(7) Reach the shore of Lac Majeur de Morgon and turn right to begin the descent towards the Vallon de la Cabane, which lies below. Follow the path from there.
(8) Walk past the sheep pens and continue along the path.
(9) Turn right to cross the dry riverbed before continuing along the path.
(10) When you reach marker 37 (elevation 2094), turn left, heading south, whilst following the fairly faint path. Do not continue straight on towards the hut.
(11) Pass the White Cross and continue the descent along the path.
(12) Cross the Ravin de Salse Morene and continue along the path that runs alongside it until you finally reach the car park at the hamlet of Le Pra (E).
