The dive

The site is known for the Caribbean reef sharks on the sand patch. A buoy at ~6 m (20 ft) holds a receiver for the government's shark research.

The tunnel to the wall forks twice: ask your divemaster which way to go. You come out deep on the wall; watch your depth and no-deco time.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): Eden Rock Diving Center's own description on PADI and the PADI site pages it contributed (with pins), the websites of Red Sail Sports (dive sites and dive policy) and Ocean Frontiers (site pages with pins, shore diving, rental), Explore Cayman, the Department of Environment (marine parks, public moorings) and the Health Services Authority (chamber). These are reef caverns, tunnels and swim-throughs with daylight in reach, from the shore in George Town and by boat on the West Wall and in East End; the requirements come from the dive centres. Certification and configurations are estimates.
