The Hanshelleren cave in Flatanger is drawing increasingly more elite rock climbers from around the world – and is regarded as one of the most unique climbing walls on earth.

Until recently Flatanger has been best known for sea eagle safaris and angling, but in recent times the world’s leading climbers have become aware of the area, more specifically the giant climbing wall known as the Hanshelleren cave.

Hanshelleren – an unknown climbing paradise

Several of the world’s best climbers have already visited Strøm in Flatanger, approx. 6 km from the municipal administrative centre of Lauvsnes, to climb what is referred to as one of the most difficult climbing routes in the world – a 9a graded route. The Hanshelleren cave is undergoing constant development as a climbing wall, and although there are already around 40 different routes here, plans are underway to bolt more demanding climbing routes, arrange international climbing competitions and make the place known internationally.

There are several climbing walls at Strøm, in addition to good opportunities for bouldering and traditional climbing. In total there are now 150 climbing routes in the Strøm area.

Unique place for rock climbing

Part of what makes Hanshelleren so unique is that the giant overhang means it never rains in the cave. Climbers always have rock that is dry and free from moss at their disposal when they wish to challenge their climbing abilities. The rock in the cave is granite, which ensures that climbers have hard, stable rock to work with when bolting and climbing routes.
