In reply to RobbieT:
Plenty to go at, especially if you have wheels. The (relatively) new German Setesdal guide covers multi pitch trad about an hour north of Evje, there is a trad single pitch crag nearby ("44,5") originally developed by British Armed Forces many moons ago. Troll Mountain use this crag occasionally, but it seems to be suffering from underuse; diff to E3.
"Go North" (also German, atrocious guide, but gets you to the bottom of the routes!) covers Nissedal and Fyresdal, also within reach from Evje, bit more driving though. Rockfax have a download for some of the better multi in Nissedal, specifically on Bærumslandsfjellet and up at Hægefjell (brilliant spot, fantastic granite bouldering too...).
South to Kristiansand (45mins) or Arendal; sport and bouldering more prevalent on the coast (27crags has some coverage).
