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. The journey to Suomenlinna takes approximately 15 minutes.
Ferry schedules can be found in Suomenlinna Online Guide under Traffic or 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. 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.
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.
Hand sanitizer is available, cleaning has been increased and keeping safety distances is reminded with stickers and posters. On ferries, you have the possibility of open air travel on deck.
If possible, we advise to avoid the busiest travel hours which on a beautiful summer day is on weekends around 11-14. During this time, you can consider arriving by water bus or traveling earlier or later to the fortress.
