This is a pleasant run in Odderøya, a former island naval base that’s now a popular recreation area. It’s just south of downtown, using the Slow Bridge. The interior part of the island is now a public park, with scenic walking paths. The terrain is a combination of open and forested, and it’s quite hilly!  A loop of the island is 3.5 km.

Start just across the bridge. There’s a large kiosk with maps. Follow the paved road, Paradeveien to Odderøyveien, which then becomes the Fyrgangen path looping around the southern part of the island. There are some great water views, and remains of old forts. There are a couple of sections of Fyrgangen that are more rugged and steeper, with some stairs. Loop back around the eastern end of the island to complete the route.
