About this site

Aquarium is a reef site off Grand Cayman in the Cayman Islands, reaching a maximum depth of around 27 metres and rated an advanced dive. Divers here have reported nurse sharks along the reef, and rough seas have also been noted as a hazard at times. This is deeper and more current-exposed than the shallow, easy reef sites the name might suggest elsewhere on the island.
