You can purchase tickets to the Isosaari ferry and guided tours from this webshop. One way trip between the Market place and Isosaari takes approximately 30-40 minutes.
If you choose not to book your return from the island, we kindly ask you to note that while there will most likely be room on the last ferries, we can not guarantee you a seat. Children under 7 years travelling with their parents travel for free and do not need reserved seats on the ferry. Groups of children under 7 years (daycare etc.) pay the same price as children 7-16 years and need an advance booking, please contact customer service to reserve seats.
Welcome to the fascinating island of Isosaari.
