[img=34803 right]the hull through the subterranean chimney[/img] ##Up reach the port of Boucharo, then the breach of Roland passing through the refuge of Sarradets.
To follow then Spanish slope the way that goes down towards the east bordering the cliff, and to take in ascendancy to the left a wide cornice full of small stones shortly before the step with chain of the Pas des Isards. Follow this cornice until the end (not very difficult but very exposed.
watch out : the falling of stones on the walkers below). Go directly up to the cave (15m, 1 spit, meeting with block in the cave, mediocre rock at the beginning).
Climb the bottom of the cave in opposition without backpack if you can (III - 6m, no points) to get out through a hole in the plateau.
the impression of getting out over the Mountain is a pass. cross to the east over the cliffs to reach a SW corridor (snow or tarteras), then climb to the right to reach the ridge then the path of the normal road. you can reach the summit also by the edge NO, but it is another route. ##Bajada From the top of the hull, go down the normal route in the circus between the hull and the tower a little to the left first to avoid the bars, then return to the west to reach the des Isards pass and climb the Roldàn breccia.<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
