Site details

Just off Long Caye on the west side of Lighthouse Reef Atoll, this shallow coral garden tumbles over a vibrant wall in clear water. Big schools of reef fish, healthy hard and soft corals and frequent turtle and ray sightings make it one of the atoll's most rewarding easy dives. It is often paired with The Aquarium and Half Moon Caye Wall on multi-day Lighthouse Reef trips.
