Oscarsborg gjestehavn
Oscarsborg Gjestehavn sits on the western side of Kaholmene, right in the middle of Drøbaksundet — meaning you're moored next to the historic Oscarsborg Fortress, the island battery famous for sinking the German cruiser Blücher in 1940. You get electricity and water hook-ups, showers, and WiFi, and harbour fees are paid via the Go Marina app or a machine south of Havnekroa. It's a genuinely special spot to spend a night, with the fortress, its museum, and the classic summer town of Drøbak just a short ferry ride away.
