Why dive here
With 327+ marine species recorded in the area - including barracuda, bull sharks, oceanic whitetip sharks, orcas and sea turtles - Lighthouse Wall offers some of Grand Cayman's richest reef diving. Water ranges 27-31°C, warmest August, September, October.
Lighthouse Wall, out on Grand Cayman's East End, feels a little different from some of the busier spots. We love that it’s usually quieter, especially if you get there before the crowds. The wall itself starts around 15 metres, dropping into a deep blue, but it’s the jagged points and sandy channels before the main event that we always spend time exploring. Keep an eye out for Hogfish rooting around in the sand, and we’ve spotted Midnight Parrotfish here more than a few times, their scales shimmering as they cruise past. The unique razor-thin formations give the wall a distinct texture. You can see big plate-like deep-water star corals growing horizontally, and if you look closely, especially near the sponges, there are plenty of small invertebrates – we’ve seen Blackberry Drupes and Pearl Blennies clinging on. There's an old, encrusted rope hanging over the drop-off, which makes a good marker and adds to the site's character. Visibility usually sits around 24 metres, giving you a good view of the wall's contours and the abundant French Grunts and Grey Snappers schooling further out. It’s a solid wall dive for anyone looking for something a bit less manicured, with a real sense of exploration.
