Audio Guide of Hemsö Fortress

The fortress is usually open every day during the summer season (from mid-June to August). To get there, drive to Strinningen and take the free ferry to Hemsö; you can check the details on its official website.

General admission for adults is around 160 SEK and includes access to the underground facilities. Children and young people usually enter free or at a reduced rate; check current prices before you go in the prices section.

Set aside at least 2 hours for your visit; the tour inside the mountain lasts about one hour. If you plan to enjoy the panoramic views and eat at the restaurant, I recommend extending it comfortably to 3 hours.

It was one of Sweden’s most secret defense installations during the Cold War, designed to withstand a nuclear attack. It is a unique time capsule that remained classified as 'Top Secret' for 50 years.

Summer (July and early August) is ideal because all facilities and the restaurant are operating. Try to go on a clear day to make the most of the stunning views over the High Coast (Höga Kusten).

Access inside the mountain is limited due to stairs and the bunker’s original structure. However, the outdoor area and the restaurant are usually accessible; contact them directly for specific options.

You are right in the heart of the High Coast, so take the opportunity to visit the town of Härnösand and its famous cathedral. You can also explore the archipelago’s unique nature or cross the impressive High Coast Bridge.

Bring warm clothing even in summer, as the temperature inside the mountain stays constantly cold. And do not leave without trying the food at the hilltop restaurant; the sea views are spectacular.
