Øyfjellgrotta cavern

A cave adventure in Øyfjellgrotta

We invite you for a guided cave excursion. Inside the cave, you can marvel at the rock formations carved by water and ice over the eons.

Øyfjellgrotta is a 500-metre limestone cave in the mountain adjacent to Mosjøen. For many travellers, cave exploration is a new and exotic adventure. Join us on this journey into the dark unknown! This cave is not particularly demanding – but with some narrow passages and places that require crawling, it’s challenging enough to give you a flavour of the sport called spelunking! There is even an underground river. From the parking lot, a short steep walk takes us to the cave entrance.

Our experienced guides are eager to show you the cave. All participants are provided with a helmet and headlight, overalls and gloves.

Important information
