Hægefjell in Nissedal for trad multi-pitch on granite domes.
First visit last September, did a bunch of HVS equivalent multi pitch lines about 200-250m long. There is a good wild camping site at the base with access to fresh water.
About 2.5 hours from Rjukan.
Easier and harder Trad options on Hægefjell, plus a bunch of other venues near by. Think there is a downloadable Rockfax supplement for the Nissedal area.
