About Killer Pillar
Killer Pillar is a boat-access Grand Cayman reef site in the Seven Mile Beach Marine Park, centered on a mini wall with a rare pillar coral colony near the mooring line. It is a classic west-coast Cayman dive with clear-water reef structure, a short navigation move off the line, and a sensitive coral feature that rewards careful buoyancy, controlled finning, and no-touch planning.
