How about a fishing safari on top of Sirdal's roof, 1000 meters above sea level, with fish of world class. Camping in the wilderness, in a simple cabin in the land of the wild raindeer, or in the old Heiberghytta: Trongenhytta in the middle of the grounds around Sirdal Fjellmuseum. This can be combined with a trip to Kjerag, for example.
