Worth a study itself, called Romsdalstrappa. 20 minutes from the top you will pass the airy viewpoint Rampestreken.

The steps provide a solid path most of the way to the top. Is well marked with signposts and red marks painted on trees and rocks. You'll be updated with signs telling you the elevation every 100 height-meters from the goal. The view on top of Nesakskla (715 masl) is fantastic.
