Cruises on M/S Kerttu

THE BEST DAY IS AT SEA

Cruises on M/S Kerttu are organised in Uusikaupunki during the open water season. On board Kerttu, you can cruise to the lighthouse island or do a sightseeing tour of the archipelago. Kerttu is also available for chartered cruises.

From June to August, Kerttu sails to the Isokari lighthouse island on a regular schedule. The Isokari cruise includes, in addition to the return trip, lunch and a guided tour of Isokari as well as access to the lighthouse. There are also cruises from Kustavi to Isokari in July.

On Fridays during high summer, Kerttu does sightseeing tours of the inner archipelago: on the 2-hour evening cruise, you can enjoy the relaxing sea, fun programme, and Kerttu’s summery treats. The ship is fully licensed to serve alcohol.

Tickets for a trip to Isokari can be booked online. Tickets can also be purchased directly from the ship on the day of the trip if there is room left. For the sightseeing trip on Friday, you can buy your ticket directly from the ship.
