Saltfjell Caves

Some 70% of all the natural caves in Norway are in the Saltfjell, and the Grønli Cave to the north of Moi Rana is a celebrated tourist sight. The limestone and marble which are the predominant rocks in the Saltfjell have been dissolved by the numerous watercourses in the mountains, thus forming the caves. The famous Saltfjell marble is still worked on the fringe of the National Park.
