Cruises on M/S Kerttu are organised in Uusikaupunki during open water season. On board Kerttu, you can cruise to the lighthouse island, do a sightseeing tour of the archipelago, or spend and evening enjoying a quiz! 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.
