dans la journée depuis le col des tentes (France) et par la brèche de Roland, le pas des isards et l'arête sud.
très bref passage au piton SO.
jour d'ascension imprécis
If you already know the Valle de Ordesa normal route to Monte Perdido, this approach to El Cilindro makes the climb entirely different. A great bivouac with no tent at Balcon de Pineta. Reaching the glacier was not evident (water was falling down the couloir making it very slippery). I had to climb in parallel and use my 30m rope to help a number of people trying to go up and down. The rest of the route went smoothly as expected. Again the rope helped to get down.
Later on I learned from a guide at Refugio Pineta that I took the wrong couloir (together with many other people!) the right and easier one is a bit more to the left.
We slept in Tucarroya hut and reached the summit the next day.
A long and great climb to this mountain. After the climb to Astazús we sleep in the tent in Balcón de Pineta for climb the Cilindro the next day (very hard).
