View over the Oslofjord

Highlight • Viewpoint

Stand on the southern edge of Håøya and just let your gaze wander. In front of you, the Oslofjord opens up in its full width, wooded islands drift like green patches in the blue water, and in the distance, the coast disappears into the haze.

Oscarsborg Fortress

Highlight • Historical Site

In the middle of the Oslofjord, Oscarsborg Fortress sits enthroned on the island of Håøya. An imposing 19th-century stronghold that you can only reach by boat. Here, Norwegian gunners sank the German cruiser „Blücher“ in April 1940, giving the Norwegian government crucial hours to flee Oslo. After exploring the fortress grounds, a hike through Håøya's natural forest paths with a magnificent view of the fjord is worthwhile.

Here you can experience a little history, but also relax in the small bays and relax.
