Setergrotta – An adventure inside the mountain!

Nature took hundreds of thousands of years to carve this cave, one of the largest and most exciting in Norway. It is situated just half an hour’s drive outside Mo i Rana. Setergrotta cave has dramatic caverns, narrow marble passages and even an underground river. You’ll climb between boulders, navigate narrow passages, and really experience the special silence found only inside a mountain.

If you are flexible and manage to squeeze through Brevsprekken (The Mail Slot), you’ll find yourself by a fish dam where tiny trout live in silence and total darkness.

The cave tour is physically somewhat demanding, as nothing special has been done to facilitate passage, although no past experience in cave exploration is required. Before the tour, your guide will equip you with a helmet, headlamp and coveralls. Be sure to have suitable footwear.

Dress for the cave trip
The temperature in the cave is constant year-round, about 4˚C (39˚F). We recommend that you wear warm, comfortable hiking clothes and sturdy footwear so that you’re okay with getting a little dirty. However, we’ll equip you with coveralls, a helmet, and headlamps. Gloves are required in the cave – you can bring your own or buy a pair of gloves from the guide for NOK 25.

Group tours
Groups may book guided tours at other times than the fixed schedule, and also at other times of the year. In addition to the tour, you can even book dining inside the cave.

Other activities in the area
The town of Mo i Rana is surrounded by fjords and mountains. Its location enables many nature-based activities and adventures. Would you like to visit the Svartisen glacier? If you think Setergrotta sounds too demanding, consider a visit to Grønligrotta. That cave is equipped with lights, walkways and stairs.
