This is a easy way to get into the archipelago from Mariehamn (and if you visit Åland you should get out in the archipelago!)
The island has both a museum and a café.
Get there between 13-15 in the afternoon, and you will see a number of ferries passing by.
If you don't have your own boat, you could use a boat taxi service, for example: http://www.fiskelyckan.n.nu/
