Turkart til Gompen på Sanna / Norgeskart

The Træn Mountains are among the most iconic and spectacular mountains in Helgeland. Far out towards the open sea, they stand as a sharp and sturdy barrier against the westerly winds. Gompen is the southernmost peak, and thanks to the construction road leading to the radar station at the top, it’s a very straightforward hike.

The hike starts from the express boat dock and first takes you through the village on Sanna. Here, there are mostly vacation homes and only a few permanent residents, but if the community center is open, we recommend stopping by for a cup of coffee after the hike.

After a short distance, you turn left and head west, ascending between Trænstaven (the solitary peak that stands like a monument on the island) and Breitinden. Here, you begin the climb up the mountain, through a tunnel. The tunnel is not illuminated, so you’ll need to bring a headlamp or flashlight. The path is steep here, but it soon becomes easier once you’re outside the tunnel.

Out of the tunnel, the path flattens out a bit, and you reach a ridge between Mjåtinden and Gompen. Here, you’ll enjoy a fantastic view towards Sanna and Husøy in the east, Holmen, Sanna, Dørvær, and Selvær in the north, and islands like Nesøya, Hestmannen, and Lovund in the distance.

On the way down, you might spot the trail that takes you on a shorter but steeper route down from the mountain. This trail traverses much steeper terrain and is less maintained. It’s recommended only for experienced hikers wearing sturdy hiking or mountain boots and should be avoided when the terrain is wet and slippery.
