The 12-hour Suomenlinna ticket is valid only on the ferry to Suomenlinna and it does not include a right to transfer to other public transport modes. You can purchase a Suomenlinna ticket in advance loaded on a single-charge card. The ticket is valid from the time it is first shown to a card reader. You do not need to press any of the card reader’s buttons. If your ticket is valid, the card reader emits an audible and a green light appears. To check the expiry time of your ticket, hold the card on the reading area of the card reader.
Tickets purchased from ticket machines are valid from the moment of purchase.
