Access by road: in Aulus, park on the banks of the Garbet.
(S/E) From the roundabout, take the road towards the centre, then the second road on the left to reach the area below the church.
(1) Take the road downhill and the path that runs alongside the first house. The path passes through gardens, at the foot of the Fontaine de Curte (on your right). Follow this well-marked path through the woods. It leads to the Crambau valley and the Crambau stream.
(2) Follow this stream and wade through it until the valley narrows.
(3) The path runs along the right bank, climbing via two tight hairpin bends, and the steep ascent begins through the forest. Follow theGRP® signs carefully, as the path is poorly marked due to the leaves. The path emerges below Mont Béas into a high-altitude meadow and heads left to reach the ridge just above the Col de la Lau.
(4) Return via the same route to the car park on the banks of the Garbet (S/E).
