The normal route of Piton Carré is across the Glacier d'Ossoue, the same approach to all the peaks over the glacier of Vignemale Massif.
Getting ThereSee the main page to approach to both trailheads, Barrage d'Ossoue and Pont d'Espagne-Oulettes de Gauve.
After 3h of walk from Barrage d'Ossoue or 1h from refuge de Bayssellance we'll arrive to glacier across the normal route of great part of the peaks of Vignemale massif.
We'll go in direction to the left of glacier to border the crevassess of right side, following the normal approach to the Grand Vignemale (3298m). The glacier is long but whitout problems we'll arrive near to the bottom of Piton Carré, before the Breché de Gaube (3152m) and Grand Vignemale (3298m). We'll leave the route of big peak, for the moment if you dont' have climbed this prestigious summit, and we'll go to right to reach the bottom of the peak lightly to left searching a point between the little fore-summit of left side and the South face what descent from the summit. The conditions are very differents each year according with the present of snow on the exit of glacier. The wall have 30º or 35 º with snow and it's necessary a good technical use of crampons and ice-axe.
Without snow the best access is the rock of left side. The rock-climb is easy (I+) but it have a lot of stones in a hard slope. The wall have 40 meters but the first 15 meters are really a walk over the free stones. The section of rock-climb (I+) have 15 meters just in the center, and the last 10 meters have a new walk with less slope to the narrow summit.
