On Grötö in the northern part of the archipelago there are only about 100 residents year round, which makes Grötö the island of tranquility. There are no cars and to get to the island you first have to go to Björkö and then hop on the ferry from there.
Grötö has a child friendly beach and a small marina with space for about 15 boats. There are both lush forests and bare rocks. Västerhav is a conference hotel where you can spend the night.
