Ennerdale Wreck
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily, so treat everything here as planning ranges.
The RFA Ennerdale, a British fleet tanker, struck an uncharted rock and sank off Mahé in 1970; her crew got off safely, and demolition of the fuel-laden hull afterward left the wreck broken open rather than intact. That suits the fish fine. Fifty-plus years on, the plates, ribs, and machinery spaces form a steel reef where giant morays lie thick (several to a section), grouper shelter under the hull curves, batfish escort divers along the length, and rays rest on the surrounding sand. Depth and occasional milky visibility make it an advanced dive; penetration is not the point, life is.
The moment you come for: Moray-dense broken tanker; grouper and rays around 30-meter sand
Topography: Broken tanker wreckage spread across flat sand at around 30 meters
Current: Sits in open water northeast of Victoria; mild current with occasional low-visibility days.
Know before you splash
Hazards: Depth for the full tour, jagged steel, and changeable visibility.
Conservation: The wreckage is sharp and unstable in places: look through openings, do not enter.
Nitrox: Worth it here: profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).

"Charted here" species were listed by our editors from the sources on this page. Counts are GBIF occurrence records: observations logged within about 5 km of the charted position since 1990, matched only against the species in our catalogue. They show what has been seen there, not a promise of what you will see.
