About this site
The Thor Star wreck lies off Pserimos, a small island in the Dodecanese between Kalymnos and Kos in the southeastern Aegean, and is generally reached by boat from one of those two islands, which serve as the main diving bases in this part of Greece. The wreck sits on a sandy bottom at a maximum depth of around 23.5 metres and is rated an advanced dive. Nudibranchs are a regular sighting on the hull, and divers have also reported black longspine urchins, damselfish, Indian lionfish, red squirrelfish, rivulated rabbitfish, scorpionfish, snapper, and tuna around the site.
