To get to the starting point of the hike, go to Aiguilles (05470) and enter from the Abriès side.
A small sign will point you in the direction of "Le Lombard". This is a forest track (dirt with stones).
You will need to drive slowly to protect your car, and as the track is not wide, this will make it easier to pass other users (cars, cyclists, hikers, etc.).
Follow the track for 3 km, then turn right towards Bergerie du Lombard.
After 1 km, you will arrive at a small car park, which is the starting point for the hike.
(S/E) From the car park, take the track to the left towards the sheepfold above the car park. After the sheepfold, take the path (there is a signpost there). Follow the path for 4 km (several tracks sometimes intersect) and you will reach the first lake, Le Grand Laus.
(1) Go to the left of the lake and reach Lac Mézan.
(2) At Lac Mézan, the main path goes to the right, but take the tracks on the left to reach Lac Petit Laus.
(3) Continue across the scree (which includes a stream bed feeding Petit Laus) to the right of the lake.
(4) From the scree, the hike becomes more difficult and there is no longer a trail. It is more of a trail.
Once you have crossed the scree, head to the right until you reach a sort of drinking trough marked out by stones.
(5) Turn your back on it and head north to reach the ridge.
(6) Once on the ridge, follow it to the right towards a small summit.
The descent to a pass (access to Les Chalps or Le Grand Malrif) and Pic du Malrif is via a small passage between rocks. This passage is narrow and dangerous, so take care where you place your feet. There may be another passage, but I haven't found it.
Once you have crossed this passage, follow the ridge to the pass.
(7) At the pass, continue along the ridge to reach Pic du Malrif.
(8) From the peak, take the path that descends towards Lac du Grand Laus, following the ridge.
(1) Once you reach the lake, take the path back to the starting point (S/E).
