Vallisaari is a former military island between Suomenlinna and Santahamina, open to the public since 2016. Two marked trails loop past old fortifications, varied plant life and sea views: Alexander's tour (3km) and the Kuninkaansaari Island tour (2.5km). Visitors are asked to stay on the trails.

There are water points, dry toilets, picnic tables and a café. It suits kids who can walk a few kilometers.
