The island can be reached with the service route spanning Nauvo – Seili island – Hanka. The car and passenger ferry m/s Östern travels the route three times per day during the summer season between 10.05. – 08.09.2024.. A stopover in Seili island is highly recommended.

Sauna house near Rantapiha with two changing rooms and a sauna room. The sauna is open to the public from noon to 8:00 PM. The cost is €2 per adult, which is simply dropped into a box. The stove must be heated with wood, which is located in an adjacent shed. You can easily cool off in Lake Savojärvi. Those who prefer to be on their own can book the sauna in the morning or from 8:00 PM to 10:00 PM. There is a drinking water tap outside the sauna house.
