About Trollveggen (Troll Wall)

Trollveggen is the tallest vertical rock face in Europe, rising 1,000m+ from the Romsdal valley floor with the top overhanging its base by up to 50m. Rock is Precambrian gneiss — banded, foliated, and with sections of variable quality that make big-wall climbing here genuinely serious. Not a crag for casual visits: the base sits at low altitude but the wall reaches 1,700m, so the summit weather can be radically different, and rockfall from the shattered top sections is a documented, ongoing hazard. Seepage is medium because the gneiss foliation planes hold water and release it slowly down established drainage lines. The east aspect catches morning sun but the sheer scale means shaded sections stay wet for days after rain. Best conditions: an extended anticyclone in mid-summer. The valley floor forecast here is what the site displays; the summit will always be worse.

Region: Romsdal
Rock type: Gneiss
Aspect: east-facing
Altitude: 100m
Exposure: high
