Agia Marina beach is a bit more than 2km from Dapia. The beach is highly organized with sun beds, umbrellas, water sports facilities and places to eat and drink. On the one end of the beach there is the chapel of Agia Marina, while at the same spot a settlement was once discovered and its findings can be seen at the Museum of Spetses.

In Agia Marina you can get by bus and your own car or on foot.
