Starting from Refuge du Chambeyron.
(S) Head north on the GRP "Tour du Chambeyron".
(1) At high point 2628, head off to the right, up towards Lac Long. Go around the left-hand side of the lake. Then take a right keeping to the foot of the debris cones. Head east until you get to Lac des Neuf Couleurs.
(2) Next take a sharp right turn (south) and head up a steep and windy trail. At the end of the bends, reach Col de la Gypière from the side, to the east.
(3) Cross over to the southern slope of the pass and head strait downhill. As the slope gets smoother, head left towards Bivouac Barenghi.
(4) Keep heading south within a mineral landscape. Go around a rocky ridge, circling around to the left hand side. Head north-east, going through a grassy area and reaching Colle dell' Infernetto.
(5) At Colle dell' Infernetto, locate what seems to be a wall from afar to the north: that's the climb to Colle di Ciaslaras, the next passage point of this stage... In the meantime, start heading down the Colle dell' Infernetto: it's a narrow trail, with lots of bends and handrails to help you through the tricky parts. You'll reach a grassy area which is just about level. Keep heading north. At the change of gradient, the climb to the pass is carried out on scree.
(6) Keep going north and head downhill on scree. Turn right (north-west) reaching Col de Marinet.
(7) Head north on a trail outlined on the slope directly below a ridge to the right-hand side (La Roche Noire on the IGN map). Get to the southern end of the largest of the Lacs de Marinet.
(8) Go around the left-hand side of the lake and go along the right bank of the smallest lake. Keep heading north then turn right to cross the lake's glacial rock bar on the way down. Head east regaining the GRP "Tour du Chambeyron" and "Tour du Bric de Rubren" trail.
(9) Take the trail to the left. Head down towards a landscape with lawns. Go past Bergerie de Mary. You'll notice some renowned climbing schools on the slope opposite the small valley (to the left-hand side). You'll reach a wooded area where the trail gets a bit windy. Once you're out of the wooded area you'll reach Ubaye River.
(10) Cross Ubaye River and take the path to the left (west) leading up towards the church. Keep heading west, quickly reaching efuge de Maljasset.
