Hi, im a swedish climber who has been a lot i Norway climbing.
I would say Nissedal for rockclimbing and Rjukan for ice.
Nissedal is a lot more weather stabile than further north.
Nissedal offers clean granite walls with crags or friction parts that are boltet with
anchors on each pitch.
I've got a small pdf-guide that i can e-mail you, and if you go there you shall by the most
actual book up there at the climbing center. Tho whole are has over a 1000
different routes - bring food and drinks since it is expensive in Norway.
Observe that it is possible to put your tent up where ever uou like in scandinavia by law as as you dont litter. Water is drinkable up there so you wont need to bring any.
Best regards and don hesitate to ask for more information.
