In reply to kenr:
hi just to add a bit more to ken's post I live 25 mins from Ailefroide and it is an amazing place to climb but i understand the comments about it getting a bit samey if non stop for a week or two,
as Ken mentioned there is so much rock around here that it is easy to mix it up, the Cerces is one of my favourites area 50ish big limestone faces and towers and normally no one there, it is about and hour from Ailefroide and has longer walk in's up to 2 hours, most of the routes are fully bolted (it says in the guidebook) but have an alpine/mountain feel, up to 400 meters in height
also there are some amazing routes on the Tenailles montbrison three spires and faces that can be seen from Briancon
both these areas are not in the new sports climbing guide (briancon climbs) but in the big route guides Oisans Nouveau Oisans Sauvage
multi pitch in the new guide are a bit shorter, there is Freissinieres but it is getting a bit polished and not the best the area has, there is also Le ponteil and paroi des lys both are 200 meters in height and down in the valley so gets lots of sun they are about 45 mins from Ailefroide.
over 3300 route in the sports book + the big wall one and a few via ferrata's if you fancy a easier day,
if you would like any info drop me a line rob@dream-trails.com
cheers
