1/ From the Pla de la Lau car park (alt 920 m) follow the rich left as far as
2/ the Caussis hut 3h - 1859 m
Turn right along the flat path (GRT 55) through rocks and meadows. When you reach the bottom of the valley, cross a stream before continuing slightly uphill to reach
3/ l'Etang Rond 3h20 - 1929 m
The path skirts the lake, then crosses a rocky chaos (névé in early summer). The climb becomes steeper and more precise, with several passages equipped with handrails. You will soon reach
4/ Etang Long 4h05 - 2125 m
Do not take the left-hand route up to La Claouère (Chemin de la Liberté). At the lake spillway, take the right trace that rises for about forty meters, then through a terrace and a rock passage equipped with handrails. Further on, the route descends to the edge of the lake and crosses several rocky passages. You then come out at the bottom of the cirque, which is often covered in snow, and from there you climb up the steep couloir, the first part of which is more to the left depending on the snow. You finally arrive at the

Tricky passages
Can be enjoyed from June/July until the first snow. The route presents a number of difficulties. The sections equipped with handrails may have been damaged or covered in snow (check with the information offices) and the ascent to the port of Barlonguère is snowed in late in the season (ice axes and crampons are useful at the start of the season).
