Cabane Bertol from the route from Arolla (photo by Steve Watson Jul 2005) The site of this hut is just superb - it is reached by a series of chains and ladders (although the old vertical ladders have been replaced by a much easier aluminimum stair type ladder) - not a place for vertigo sufferers. Views from the hut 'deck' are just superb on a clear day Well worth a visit.
