In reply to TobyA:
3 days... Man I hope you´re lucky with the weather. Top tip would be to bring a car so you are able to move down south to Gothenburg area or Kullaberg if it´s raining. Or Norway or inland if it´s really bad. If its a bit wet and the rain aint pouring, Kleven with its extremely rough granite is usually climbable, Tjörnbroklippan (sport) dries fast.
Second tip would be to bring lots of gear if you intend to onsight a lot at your limit, a lot of the classic routes are in the 35-40m range so bring plenty of cams.
Third, stay, as stated above, at Klattertorpet. The owners Hanna&Petter have probably climbed everything worth climbing in Bohuslan and will be more than happy to give you pointers about routes, access etc.
Fourth, the grades will feel pretty hard compared to Lofoten grades (Lofoten 6= roughly 6- bohuslän) and more like other northern Norway.
Fifth, have a look at
www.headwall.com, www.8a.nu,
and more importantly www.sverigeforaren.se and
http://www2.idrottonline.se/default.aspx?id=218157 for new routes and updated access info. There is a lot of access info which has changed, like where to park, closed crags during some periods etc etc.
At the crags mentioned above I would def. add the following at beloved Skälefjäll.
"En liten bit granit" sv6 (with Hassan chop finish for extra lenght, same grade, "Hot´n tots" sv6-/6 and if you like diedre, "Björnbärssnårigt" sv6. The beauty Granitbiten at soft and well protected sv7- might also be within reach, a wild guess, E2/E3? Skälefjäll is sadly not only climbing heaven but also tick paradise, so check yourself carefully after....
Other crags,
Högberget, lots of quality routes not in guidebook web only (headwall.com)
Svaneberget, classic crack Bergkirstis polska sv6-
Tåsteröd vatten (Nixten sv6)
Have fun! (I´m sure you will if the weather gods are friendly)
