In the Uddskatan area, visitors are only allowed to walk along the designated trail. The Tulliniemi Nature Trail is 7.5 km long in total, and the route is walked back and forth along the same path. The trail is at times difficult to traverse and is not accessible.

Along the nature trail, there are 15 information boards that share details about the area's valuable natural environment, as well as cultural heritage related to maritime history and wartime events. The texts on the information boards are available in Finnish, Swedish, and English. You can also find the nature trail's information boards online (julkaisut.metsa.fi).
