In the hillside behind "Steinen" you find Mjelvahammeren.
Park your car as showes on the map. Follow the track from the bus stop. Close to the little stream the track splits, continue on the track that goes uphill. After a couple hundered meters you will come to a broken ladder. Climb the ladder to enter the crag.
Because of the elevation of the crag, be awre that falling before the first bolt can get serious consequenses. On most of the exposed route you are able to clip the bolt before you have started to climb. The approach goes below the crag, so be aware that dropped objects may cause danger for people walking up.
