Best for advanced divers, 24-28m, boat entry, moderate current.
The Cleio shipwreck lies at depths between 24 and 28 metres, offering a combination of wreck and reef exploration. The structure has become a substrate for sponges, while moray eels inhabit its recesses. Divers frequently encounter grouper, sea bream, and yellowtail damselfish around the hull, with amberjack occasionally passing in the open water. Nudibranchs are also present for those observing the substrate closely. Access is by boat only, and the site features moderate currents. Visibility typically ranges from 10 to 20 metres. Due to the depth and potential for sharp metal and rock, this site is suitable for advanced divers who can manage their bottom time and profile effectively.
