Gulf of Finland National Park is a paradise for birdwatchers and a great fishing destination. For those looking for culture, the park's islands have oodles of war history and numerous vibrant villages to explore.

Parts of the park are closed to the public during certain times of the year. Check them out on the map before heading for a trip. Please respect the signs!


The best way to explore the park is by boat. Whether you are into sailing or motorboats, the outlying islands of Finland's easternmost coastal regions offer exciting adventures far away from the mainland and people. Boats can be moored in marinas on the bigger islands of the park. Moorings and services for boaters are also available on the nearby islands of Tammio, Kaunissaari and Haapasaari. The nearest bigger ports are Kotka and Hamina. Read more about services for boaters.

There are also ways to explore the park if you do not own a boat: A regular ferry service operates between Kotka and Ulko-Tammio at weekends in July. There are also taxi and charter boats in the area.


Fishing is a great way to relax.


The eastern parts of the Gulf of Finland are famous for the many species of seabirds that nest there. The birdwatching tower on Ulko-Tammio Island is one of the best places in the park for listening to the sounds of beating wings and seeing the majestic spring migration when arctic waterfowl and waders flock northwards for the summer by the hundreds of thousands in May.

  • Canoeing: There are no marked boating or canoeing routes in the park and canoeing is only recommended for experienced paddlers.

Paddlers planning a longer excursion are advised to contact local canoeing clubs (, in Finnish) for information beforehand.

The island's observation tower has magnificent views across the sea. The views from the observation tower on Mustaviiri Island are also breathtaking. Mustaviiri Island is home to a mysterious stone labyrinth and a tiny World Heritage Site: one of the original station points of Struve Geodetic Arc, a chain of survey triangulations. The park also offers many other unforgettable experiences: Feel the power of the sea, watch the migration of arctic birds, visit vibrant villages on the islands, and learn about underwater flora and fauna, seals and the history of fishing, smuggling and seal hunting in the area.
