Generally it's possible to climb from Refugio de Respomuso (3h to summit) or directly from dam of La Sarra (5h45min to summit).
Slope: 1750m (LaSarra) or 1030m (Respomuso).
The stepcrossing of Brecha Latour is grade II or II+ of 30 meters equiped with metallic stakes. The rope can be necessary for the inexpert people.
From Refugio de Respomuso we take the path with signal a few of meters in the route that we followed the previous day. We walk across steepy slopes with grass and rock to reach an upper part with a signal to Frondellas on left side but we follow the cairn of right side waling under the big wall of ridge Le Bondidier. In direction W-NW is the access to the Brecha Latour (Latour's break) to the right of the peak Aguille Cadier.
The access is for a hard channel with snow, rock or mud, a little hard for the inexpert mountaineers (rope, helmet,...). In the right side of the channel are the spectacular metallic stakes for climb (grade II and II+) for 30 meters. In the top of the break (2965m, 2h 40min), we descent a little bit and we follow to the north over the balcony in the middle of the hillside to reach a col between both summits turning to left to reach the summit (3144m, 3h).
In winter with the snow on the stakes of the Br. Latour, we must follow the coulouir to the final (40º) and turn to the dangerous ridge of the right side (50º, exposed).
For the descent you can use the route of Gran Diagonal, but if you want to return across the same route the rappel is very advisable.
Rope, harness, helmet (if you want). The expert mountaineer generally climb without rope on summer.
Spring: crampons, ice-axe.
