From Plan de Besurta (1.900 m) take the trail to Aigualluts. Once there go towards Valle de Barrancs. Ascend Glaciar de Barrancs to the circus between Aneto (3.404 m) and Espalda de Aneto (3.343 m).
Once on the upper part of the glacier turn to the left, avoid a rocky wall traversing from right to left and reach Espalda de Aneto (3.343 m). If there aren't cornices the slope is about 50º. It's not necessary to climb Espalda de Aneto (3.343 m), then ascend on the snowy slopes (50º) to the right just until reaching the rocky wall.
Crampons. Ice axe, rope, warm clothes, map, compass and altimeter are recommended principally out of the summer. A snow anchor, Deadman or pickets would be recommended as well.
