Slettafjell is a long, quiet slab wall in Åseral, Agder, in the hills between Setesdal and Sirdal, about an hour and a half's drive north of Kristiansand. Most of its routes are trad lines of four to eleven pitches, cleaned and bolted by Nils Rune Birkeland and friends (Fri Flyt); Trygg og glad is the one fully bolted line and one of the wall's most classic routes. From the parking point listed on brattelinjer.no the mapped approach path is about 425 m long with about 140 m of ascent. The usual season is late spring to early autumn (inferred from the altitude and the logged ascents, which run from May to early October).

The classic bolted line on Slettafjell, a long, sociable slab day at moderate grades with fine views. Two easy pitches lead to steadily harder slab, with a 6a+ crux on the 50 m sixth pitch that you can pull through on the bolts. It finishes at a belay below the top of the wall, and you abseil the route.
