About Damtjern

Damtjern is one of Norway's most historically important sport-climbing crags — 40 km NW of Oslo in Krokskogen forest, Ringerike municipality in Buskerud county. Rock is distinctive red "Drammen granite" — Precambrian, excellent quality, with the vertical to slightly off-vertical walls giving 10-25m routes. The crag was developed 1986-1990 by the pioneers of Norwegian sport climbing, and hosts the country's first 8+ (Stive Dempere) and first 9 (Marathon). Grade concentration is 7+ to 9+ — this is a hard sport crag, not a beginners' venue. South-west aspect catches afternoon and evening sun; well-known around Oslo as the classic after-work destination. Continental inland climate is drier than the Bergen/Voss west coast, so Damtjern often climbs when the whole west of Norway is wet.
