Ennerdale Wreck

The Ennerdale Wreck is a large oil tanker that sank in the 1970s following a navigational accident, located northeast of Mahé in the Seychelles. The vessel measures approximately 200–270 metres in length and lies broken apart on the seabed, making it the largest wreck in the Seychelles. Access is by boat only, as the site sits far from shore.

The wreck rests at depths ranging from 12 to 30 metres, with the shallowest point around 12 metres and the bottom reaching approximately 29–30 metres. The scattered, sometimes disorienting wreckage spreads across a wide area, and dense coral growth has established itself across the hull. Swim-throughs are a notable feature of the site.

Marine life on the Ennerdale is varied and well established. Nurse sharks and grey reef sharks are frequently encountered around the structure, along with giant groupers, reef sharks, yellow snappers, rays, eagle rays, octopuses, moray eels, and lionfish. Coral growth on the hull adds to the ecological richness of the site. The best seasons to visit are March to May and October to February.
