Lidön is an island part of the Archipelago foundation. The east harbour, Österhamn offers a nice shelter from all winds except E-NE. It is a very popular stop over tor those going to and from Åland and Finland. Often crowded, but the jetty can be used to moore and remains usually free. The sea bed is covered with seaweeds making it difficult to anchor in the bay.
On the west side of the island is a martina in Båthusviken, with a very nice restaurant, the Värdshus. You can bike across the island or walk through the gravel path all around the island.
Lidö is accessible by a ferry operating from Räfsnäs.
Lidö is at the crossway of the fairway to Åland, to Norrtälje and to the north.
The bay is protected from all winds but east/north-east.
