A large part of the extended archipelago is included in the nature reserve of Storö-Bockö-Lökaö, which is nearly two thousand hectares in size and known as the “Möja reserve”. With its meandering canals, narrow straits and exciting small islands close to each other, the region is highly valued and frequently visited by boats.
At many locations between Möja-Södermöja in the west and the Björkskär bay open to the sea in the east, we find not only idyllic intermediate archipelago with old grazing and a rich herbal flora, but also barren and exposed outer archipelago.
It is possible to find evidence of human activity all over these islands. Grazing animals are still kept on Lökaö. Here, large strawberry cultivations dominated from the turn of the previous century until the 1960s. There are, however, also limitless areas of rolling pine forest and secret marshland.
The Bockö-Sillö strait passes right through the centre of the island group and is used for boat traffic between Möja and Sandhamn. Fresh water is available at many places. And the sauna on the eastern side of Ostholmen is well-worth a visit.
