In reply to mrbird:You're driving via Denmark?
Well there's a lot - Setesdal is northwest of Oslo, past Nissedal. You can drive up the middle, past Hurrungane/Jotunheim, or up the coast via More and Romsdal. The mountains in M and R have large elevation gains, but they aren't very high as they start at sea level - is that what you want?
Do you have a partner to climb with?
yr.no for the weather. Don't trust foreign (non Norway) sites. Keep a close eye . it can vary a lot locally.
