Park at the Millefonts car park at the end of the road of the same name, which you take from Saint-Dalmas (Valdeblore).
No markings
(S/E) From the car park, climb the embankment to take the path that climbs northwards into the valley.
At a flat section, you will join theGR®52, which arrives from the right.
Red and white markings
Continue on the left, following the GR®. The slope becomes steeper and, a few minutes later, you will arrive at the Col de Veillos (marker no. 83) with a beautiful view of the Vallon des Millefonts and, in the distance at the end of the ridge, the Cime des Lauses.
Yellow markings
(1) Continue opposite on the path that descends on the other side of the pass towards Col Ferrière and Lacs des Millefonts.
After a short climb above the Vallon des Millefonts, you will arrive at the first lake, Lac Petit.
(2) Cross the small stone bridge at the lake's spillway and climb the small hill on the left to join a path that leads away from the lake and quickly gains altitude in a north-westerly direction.
There are very few markings in this area of meadows.
After a flat section, cross a small stream and continue climbing on the other side of the valley, following a few cairns. Then turn left into a corridor leading to the foot of the pass. Continue to the right to reach Col Ferrière (marker 262).
No markings
(3) From Col Ferrière, the ascent to Cime des Lauses is made by heading due west on a grassy slope. Follow the few tracks and climb the switchbacks to the ridge, which offers a breathtaking view of the Tinée valley and Mont Mounier in the distance.
Then turn right to reach the summit, marked by a large cairn.
(4) After a well-deserved break to enjoy the view of the Mercantour... retrace your steps to return to Col Ferrière.
(3) Continue straight ahead, heading east, climbing the ridge towards Brec du Col Ferrière. Pass through the middle of this relatively flat summit and descend towards a small pass marked 2458 m on the IGN map.
Then climb straight up, following the ridge path towards Tête des Margès.
If you miss the path that leads directly to the summit (as I did), pass a rocky outcrop above the main path and climb around it on the right to reach a first summit marked by a cairn. Then head for the second summit to the north-east for a panoramic view of the Vallon de Mollières and the border peaks of the Vésubie.
(5) Continue along the ridge path, descending towards a new pass (altitude 2,496 m) and climb back up towards the Tête du Barn, which offers a beautiful view of the Lac du Barn and the Caïre Archas.
Then descend the grassy slope towards the south to reach the path that leads to the Col du Barn (marker 84).
Red and white markings
(6) From the pass, descend to the right on theGR®52towards the Lacs des Millefonts.
Pass Lac Gros (slightly heart-shaped) and then Lac Long (colonised by aquatic plants).
Continue along this marked trail through a rocky landscape to Col de Veillos.
(1) Descend on the left to return via the same route as on the way up to the Millefonts car park (S/E).
