Why dive here
With 327+ marine species recorded in the area - including barracuda, bull sharks, oceanic whitetip sharks, orcas and sea turtles - Big Dipper offers some of Grand Cayman's richest reef diving. Water ranges 27-31°C, warmest August, September, October.
The Big Dipper, up on Grand Cayman's northwest tip, is one of those sites where the visibility just stretches out forever. It’s a deep wall dive, maxing out around 26 metres, and the drop-off is sudden, like someone sliced the ocean floor with a knife. We love floating along that edge, feeling the cool water from the abyss brush against our skin, scanning the blue. What makes it special for us is that combination of the wall and the sand channels intersecting the reef. You’ll spot the usual suspects, of course, angelfish and butterfyfish gliding past. But we often find those smaller, more cryptic critters here too – look for the roughhead blenny popping its head out of a hole, or an eyed flounder trying its best to blend into the sand. Keep an eye out for Miss Darlington, our friendly resident porcupinefish, she’s usually lurking around the coral heads. We’d suggest going early in the morning; the light hitting the wall as the sun rises is pretty spectacular. This site is perfect for divers who appreciate dramatic topography and are happy to slow down and hunt for the tiny wonders.
