Ferry schedules and duration of the trip
The ferry service is operated by the Helsinki Region Transport Authority (HSL). Depending on the season and the time of day, ferries run 1 to 4 times per hour from the morning until the night throughout the year.
Please see the detailed ferry schedules here (pdf). The journey to Suomenlinna takes approximately 15 minutes.
Ferry schedules can be found also in HSL Journey Planner.
The ferry departs from the east side of the Market Square, opposite the Presidential Palace. In Suomenlinna, the ferry arrives at and departs from the main pier of Iso Mustasaari island, on the north shore of Suomenlinna.
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.
The ferry is part of Helsinki public transport. If you have a valid HSL ticket (AB, ABC or ABCD) you can use it in the ferry. Suomenlinna is in the HSL ticket zone A.
If you don’t have a valid ticket you can buy it from the ticket machine on the departure pier or via the HSL app. In the summer, tickets are sold also at the ticket booth in the Market Square ferry terminal. An AB day ticket is the best option and it allows unlimited travel for 24 hours not only in the ferry but also on trams, buses, commuter trains and metro in A and B zones. Please note that
Tickets need to be purchased before boarding. Please note, that tickets are not sold on board. See the HSL website for ticket prices.
The crossing is free with a Helsinki Card.
