It is not necessary to make a reservation for the car, but it is subject to a transportation fee. The driver and the passengers must also possess a valid passenger traffic ticket. The transportation fee must be paid in advance on land, as Suomenlinna fortress does not have ticket machines for transporting vehicles, nor do the ferries sell tickets.
The car, motorcycle or bike by transportation fee is paid to the vehicle transport payment machine. These machines are located in the terminal areas of Kauppatori and Katajanokka.
The machines accepting transportation fees accept micro-chipped debit and credit cards. The transportation fee is determined based on the size of the vehicle. The transportation fee receipt will be checked on the ferry.
