The waterbus service to the fortress runs from May until the end of September. Trip to the fortress with a waterbus takes about 20 minutes.

The waterbus departs from Keisariluodon laituri pier at the Market Square. In Suomenlinna, the waterbus departs from the Artillery Bay pier and also stops at the King’s Gate. Some waterbus departures stop at Lonna island on the way to Suomenlinna from the Market Square.

To reduce emissions, we recommend that you use public transport to get to the Market Square. There are very few parking places around the Market Square.

HSL public transport tickets are not valid on the waterbus.
