To reach the starting point of this hike from Tardets via the D26, turn left below the campsite at the entrance to Larrau, about 100 metres after the sign marking the entrance to the village, and take a small road that becomes a track. Follow this beautiful track, which is accessible to all vehicles, for about 8 km to reach a small car park.
There are red and white markings along the entire route.
(S/E) From the car park, take the track that climbs to the right; the one on the left descends towards the Holzarté footbridge. The track winds its way up to a small ford and a water intake.
(1) Ford the stream. The track levels out and arrives at a fork: take the right-hand path towards Pista and climb into the forest. The slope becomes steeper and the path is straight, but you will need to zigzag between the trees to get out of the forest.
(2) From this point, the slope is less steep and crosses a clearing covered with ferns. The path then splits in two at a small post marked with theGR® Blanc and Rouge trail markers.
(3) Take the left fork and walk until you find another small post withGR® markings.
(4) At this point, there are two paths: take the one on the right and climb up to the waterfall.
(5) Return via the same path to the car park (S/E).
