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.

1. Follow the Norwegian Mountain Code and plan according to your ability and equipment

Short hikes on easy terrain don’t require much. If you’re heading out for an hour or two in the lowlands and not gaining much elevation, you won’t need a lot of gear or be in top shape. If it gets cold or you get tired, you’re usually not far from your car.

But if you’re heading into more challenging terrain—steeper, rougher, and above the treeline where the weather is more unpredictable—you’ll need to be better prepared. You should plan the trip based on weather and conditions, be fit enough to complete it, and be ready for uneven ground, boulder fields, slippery roots, and stream crossings. That means carrying a heavier pack with extra clothes and gear, and wearing sturdy hiking boots that support your ankles.

If you’re unsure about taking on a demanding mountain hike, start with an easy or moderate one and see how it feels.

2. Stick to marked trails

A shortcut through unfamiliar terrain can easily turn into a long and difficult detour. What looks like a trail might just be a sheep path that leads you somewhere completely unexpected. If you want the hike to be as easy or challenging—and as long or short—as planned, it’s best to follow marked trails.

If you’re heading off-trail, it’s smart to follow a GPS track. You can download a GPX file from a hike description and use it on a GPS device, a smartphone app, or a GPS watch.

UT.no and the UT app offer hike descriptions with GPS tracks. If your hike doesn’t have one, you can upload a track to ut.no/mine-turer and access it in the app. It’s free, but you’ll need to create an account.

Always carry a map and compass as backup.

3. Talk to locals or join a guided hike

Locals often have useful tips about your planned hike. They can tell you where to park, whether there’s phone coverage, if the trail is wet, if rivers are high, or suggest a better alternative. Talk to the people where you’re staying, at the local tourist office, or other hikers on the trail—you might get some truly valuable advice.

The best option is to hike with a guide. You can join a group tour or book a private guide. These are experienced locals who know the area well. They’ll help tailor the hike to your needs and share insights that add to the experience.

4. Look out for cultural landmarks

Even high up in the mountains, you’ll find traces of past human activity—some hundreds or even thousands of years old. These can include ancient trail markers, signal cairns, hunting fences, huts, and shepherd shelters. If you spot something interesting, check the KulturPunkt app to see what it is—or use the app to find a cultural site as your hiking goal.

5. Remember your responsibilities under the Right to Roam

Norway’s Right to Roam means you can hike, bike, pick berries, camp, fish, and ski almost anywhere in nature. But it also comes with responsibilities—what we call the “duties of the Right to Roam.” Leave no trace, respect wildlife, and know the rules for hunting, fishing, cycling, and access in protected areas like national parks and nature reserves.
