Blue Pearl Bay is located on the north-western side of Hayman Island in the Whitsundays Group. Popular with tourists and locals for snorkelling, diving and sightseeing, Blue Pearl Bay is known for its coral and fish life including a resident Maori Wrasse. Day tours and overnight boats visit Blue Pearl Bay for snorkelling and or scuba diving. Visitors typically swim directly off their vessel, or tender into the southern beach and enter the water from the coral beach.
Diving depth is from three to 18 metres. Diving visibility is typically from three to 15 metres.
Best coral cover to be seen in shallow water off the southern beach. Scattered bommies with silty sand bottom at five to 18 metres, dropping off to coral rubble and silty sand below 18 metres. Best dive off southern beach, near Castle Rock. Shallow coral ledge (two to three metres) dropping off as descent wall to 10 to 15 metres. Wall has narrow canyons and caves making for great exploration. Strong corals near Castle Rock have some striking gorgonian fans at eight to 15 metres as well as whip corals. The shallow waters are predominately staghorn coral. Good protection from all winds except north-westerlies.
