Les Chéserys and the Aiguillette d'Argentière are fairly unique in the valley in that they offer high quality multi-pitch bolted climbing with no lifts required. Local guides are constantly adding and removing bolts on this crag, so figuring out which line your route takes is not always straightforward. The routes described here are the best-known lines and all follow features, so despite the bolting, you should always be able to find where you are using the photos. The naming of the routes isn't always particularly imaginative, with colours seeming to be a strong trend, but who cares when the climbing is this much fun?
All routes described are fully bolted and, with the exception of the routes on the Aiguillette d'Argentière, all require 2 x 50m ropes for abseil descents.
