May 16, 2026, Aussicht auf den Oslofjord

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.

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.

There's a small cafe on Håøya where you can stop for a bite to eat. The cinnamon rolls are highly recommended!

There aren't many hiking trails on the small island, but they are all beautiful and worth a detour!

A very pretty cafe. The range of cakes is huge. The cinnamon rolls taste great. You can sit inside and outside. www.g.co/kgs/5spKMY

A figurehead hangs on a building in Drøbak. The house is right at the ferry port. A little further sit the "Three Mermaids"
