Thasos – Wreck of the Thetis | North Aegean WWII Wreck

Site Overview

The Thetis is a WWII-era wreck off Thasos, associated with the island’s submarine-net defences, now resting in 12–28 m as a scatter of metal and a haven for macro life. The remains have become home to morays, nudibranchs and octopus, and the shallow depth makes it accessible to advanced divers on a single tank. Although penetration is not encouraged, swimming the bright outer structure gives a sense of the site’s history without the risks of enclosed spaces. For divers based on Thasos, the Thetis is a satisfying, easy wreck that combines a little wartime history with abundant small life, and the clear northern Aegean water makes the details easy to appreciate. It is a favourite of macro photographers and of anyone interested in WWII artefacts. Thasos – Wreck of the Thetis sits within Mainland – Northern Greece (Macedonia & Thrace) and is best described as a wreck and history dive. The water here is typically clear, and the profile — from around 12 m down to 28 m — gives intermediate divers a rewarding range of routes. Among the life you can expect are Mediterranean Moray, Nudibranch, Common Octopus, Anthias, Wrasse. The site rewards a slow, observant approach, and good buoyancy keeps both diver and reef safe. With sensible planning around weather and boats, it ranks among the more memorable stops on a Greek diving trip.
