The Eastern Gulf of Finland National Park is located far from the mainland. Reaching the national park always requires a sea journey, either with your own boat or by water taxi.

By waterbus or taxiboat

Partner entrepreneurs arrange boat transport and cruises to the national park area on request.

By your own boat

The only sheltered harbour in the national park is located on Ulko-Tammio island. In addition, the islands of Koivuluoto, Lanskeri, Mustaviiri and Suuri-Pisi are accessible by keelboat in calm weather.
