Visit the marble mines in Bergtatt

The caves are a result of mining operations since 1938. In other parts of the mountain, the mining operation is still ongoing. Today, the area where the caves are located function as a concert venue, as well as a tourist attraction in itself. A boat ride into the caves offers visitors a unique and stunning experience. 

Combine this with a trip to the Atlantic road, one of the world's best road trips. The highway zigzags across bridges and islands, to the point where the land and the ocean meet the fjord.
