Similar thrill seeing Newcastle ferry there, before noticing the 2007 :'-)
I'm going for a general exploring campervan trip Oslo -> Bergen -> Stavanger -> Oslo in a few weeks' time.
There are a couple of boulders around Stavanger, but they are quite far apart and often in rather swampy areas. Did not have the best experiences there and would personally rather go surfing than climbing if I am there. Might have missed the truly good stuff though...Hope that helps!
