In reply to tehmarks:
First, a heads up: the road linking la berarde and ailefroide (over the col) will be shut when you go, so you are limited to the west/northwest. Unless you drive round by gap that is...
RE books:
- Brailsford (ac) - more than adequate for low grade stuff even if it is dated and not particularly user-friendly
- Cambon, oisans nouveau oisans sausage - the best mountain rock book for the area, though it is in French
- for valley rock just buy the 11/12 euro little book when you're there!
If this is your first foray into alpine routes then I would stay away from les Bans. Not so much because of its difficulty in ascent, but because of its more complicated descent - it has great potential to turn into what might seem like a rather long day out. Look at peaks like the rateau from the selle, gioberney, the replat, dibona (though I personally feel the normal route is a bit of a waste of time), fetoules. These are all simple out and backs with straightforward route finding and descents.
Have fun!
