To get to the start, between the Colmiane ski resort and heading towards Saint-Dalmas, take the small road called "Les Millefonts" on the right, in a hairpin bend on the left. The hike starts from the car park at the end of the road, which is open to all vehicles.
(S/E) Take the trail above the car park to join theGR®52and climb up to the Col de Veillos via a trail that winds its way up the grassy slope.
(1) Take the path on the right that continues up the ridge, then continue along the mountainside to reach Lac Long. Go around it on the right, the path climbs a little, joins Lac Gros and continues on the left to reach the Col du Barn after a short climb.
(2) Continue the descent to Lac Long.
(3) Leave theGR®52to go around the lake on the right (no visible trail), cross the lake's spillway, then cross the grassy area and climb the mound to descend behind it and reach Lac Rond. Take a well-marked trail on the right at the bottom of the valley and reach a small lake. Go around it on the left and continue on the trail that leads to the lake's spillway, from where you can see Lac Petit below.
(4) Reach the lake via the slightly steep path and then, after crossing the bridge, continue along the path to join theGR®52at the Col de Veillos.
(1) Follow the path you took at the start in the opposite direction and return to the car park (S/E).
