The amazing marble formations of Marmorslottet took thousands of years to create. Over the years, the river gradually washed away the softer limestone and then far more slowly carved potholes, giant’s cauldrons, caves and other strange sculptural forms in the underlying harder marble. As a result Marmorslottet (“the Marble Castle”) is a very special place to visit. With your own eyes you can sense how water and ice, sometimes using sand or gravel as an abrasive, shaped the hard marble a fraction of a millimetre at a time.

Be sure to turn left at the trail fork.
Turen til Marmorslottet går for det meste på en god skogssti, men enkelte partier er lite tilrettelagt og krever litt klyving. Kristoffer Møllevik / Visit Helgeland

Take off your shoes when you enter, and take the rubbish with you when you leave

To avoid causing any abrasion, scratches or other damage to these beautiful formations, kindly remove your shoes before venturing out onto the marble. After all, you shouldn’t wear boots that might have sand or pebbles embedded in their soles before treading on a friend’s valuable wooden floor. Don’t do it here either – after all, Marmorslottet really is “a Marble Castle”!

Actually, walking barefoot or in socks enriches your tactile experience! With each step you can feel the marvellous formations that ice, sand and water took thousands of years to create.

In fact, strive to leave absolutely no trace of your visit. Please take all your rubbish with you, and pick up any that you find – plan ahead and bring a bag for this. Do not build any fires in this area. Also, there are no toilets here, so take care of your bodily needs before you leave Mo i Rana.
