About this site
Kostervraket lies in the Stockholm archipelago, in the cold, brackish waters of the Baltic Sea off Sweden's east coast. The site reaches a maximum depth of around 36 metres and is considered an advanced dive. As a wreck site among the archipelago's many islands and skerries, it sits in the kind of cold, low-salinity water known for preserving old wooden shipwrecks unusually well, though divers should be prepared for the depth involved in reaching it.
