In reply to BTphonehome:
Climbed there a few times a while ago with some locals. Endorse the other comments - Alfonso topo. its classic granite so cams go well. if you like mountain routes they are superb in which case i would recommend twin for the abs. Also climbed from refugi Ventosa - could still be snow great sport and also superb trad mountain routes - good info from the guardian. Refuge can get very busy on WE and there is ( i think ) a big public holiday in spain in June.
You dont mention grades but endorse Pistachio assassin , Blues , John lee hooker
Also - African Wall and that sector left and below the dam. Pas de l'os. both for cragging
Watch for afternoon thunderstorms. Not sure of latest rules on parking right up at the dam - there were some restrictions. Risk of theft from vehicles parked there.
