In reply to dodfoster: I'm in Gothenburg right now and spent yesterday climbing in Utby. Try to use www.8a.nu and search for either "Utby" or "Fjällbo". It's situated close to the city and you'll have 300+ routes on excellent granite. Roughly the same rules apply here as in Bohuslän so you'll hardly find any bolts. Trad is the way of western Sweden
It can also be useful to try www.sverigeforaren.se and search for Utby/Fjällbo. The site is in swedish but has some pictures and route descriptions. The guide book that covers the gothenburg area also has some brief descriptions in english for every area. It can be bought in climbing stores in the city, try "Fjällsport" which has really nice staff.
