In reply to MattDTC: If you're driving you have the ability to visit a few different areas and cherry pick the best routes and weather - ideal! A couple of specific suggestions would be:
Salbitschijn (Switzerland) - a load of mega routes to go at here of varying grades and lengths on the most perfect alpine granite I've ever encountered. I've personally only done the Sudgrat (VS/HVS and 20 something pitches) in the area but would say it was the best rock route I've done anywhere - long, sustained, great moves on perfect rock, striking line - the list goes on. It's sportingly bolted with maybe 2-3 bolts a pitch, (which I got the impression were as much to show the way as anything given there's plenty of cracks) so a small trad rack is needed. Virtually every pitch would be a 2 or 3 star classic in it's own right on a single pitch crag. There's loads more to go at from the same hut and I'm psyched to get back sometime for more.
Dalmazzi Refuge (Courmayeur) - again lots of long rock routes (up to 22+ pitches) to pick from at a variety of grades on good rock. There's even an extensive free guide online if you do a quick google.
The Swiss Plaisir guides are pretty good for the kind of routes you are after and cover some limited areas outside of Switzerland (usually along the borders) too. Have fun - long rockaneering is definitely where its at for Alpine summer!
