Tjoarvekrájgge

Tjoarvekrájgge is a limestone cave in Bonådalen valley with an extensive network of underground passages and multiple chambers. The system extends through interconnected corridors that have been shaped by natural geological processes over time.

Swedish cave explorers discovered this formation in 1993 and began systematic mapping work shortly after. The following decades brought gradual exploration and scientific documentation of the system.

The name comes from the Lule Sámi language, spoken by indigenous peoples of this region. This linguistic connection reflects the long presence of these communities in the Sørfold area.

Access requires special equipment and climbing skills due to the complex structure and depth of the system. Visitors should be aware of the challenging conditions and come properly prepared.

This underground system is the longest in Northern Europe and still has unexplored sections. Scientists continue to discover new parts of the network, showing that its complete extent remains partly unknown.
