Vänö is a former fishermens village where all the houses are situated close to the southern sea shore. There you can also rent accommodation in cottages or appartments with 1-2 rooms with total space for max 25 people. Cottages called Solbacken (”Sunny hill”) and Stens are available, you can also book them on this site.
For a stronger experience of the nature you can rent a tent on the island. As well as kayaks and other equipment.
The boat trip with ferry Stella takes one hour from Kasnäs harbour on the mainland. You can easily take your car to Vänö, but call the ferry in advance to book place for your car.
