Caits Reef is a beginner-friendly reef dive in the Cocos (Keeling) Islands that is often used for Open Water training. The site combines a sandy bottom with nearby reef structure, so navigation stays straightforward while still giving divers a proper reef setting. Branching coral is a highlight here, and the reef is known for regular sightings of blacktip reef sharks, surgeonfish, and parrotfish. It suits new divers best when conditions are clear and calm enough to keep the route simple and the wildlife easy to enjoy.
