Limestone crag with slabs from 30 to 130 meters. The climbs are up and down a walking path carved in the moutain (GR10).
Mainly sport climbing, well-equipped but some trad routes as well.
Access from the N134 from Oloron-Sainte-Marie towards the south (follow "Tunnel du Somport"). Just after Etsaut you can see a fortress in the mountain (the Fort du Portalet) - a few hundred metres before, take a road on the left (follow "Chemin de la Mâture" sign), go past a first car park and continue a few minutes up a little road to a second car park.
