I was there earlier this summer. Are you getting any orienteering in? One of the highlights of my June travels was stumbling on an urban orienteering event in Ohrid, Macedonia. I didn't run a course, but it looked like fun.
Thanks. Since this was a touring trip with my dad, I didn't get in any O this time. Looked at the sprint map in Kristiansand that was discussed in the "Sprint Traps" thread but it was pretty far from city centre for the short time we had there. And it appatently included some restricted / fee areas (eg the zoo), so I didn't think I'd be able to just run it any way.
