Dive profile & how the dive runs

A dive at Lighthouse Reef typically starts with a boat entry directly over the reef. Divers descend slowly, beginning their exploration along the vibrant coral gardens that adorn the granite reef structures. The route usually follows a gradual depth progression, allowing for ample time to observe the diverse marine life in various depth bands. You can navigate around the reef, exploring crevices and overhangs where smaller creatures often hide. The relatively mild currents permit a relaxed pace, providing excellent opportunities for photography and close observation. The turn point is determined by air consumption or planned bottom time. The ascent typically follows a controlled path back towards the boat, with the safety stop conducted at 5 meters over a shallower part of the reef.

Underwater photography

Lighthouse Reef offers excellent opportunities for both wide-angle and macro photography due to its diverse reef system and calm conditions. For wide-angle shots, a fisheye or wide-angle lens is ideal to capture the expansive coral formations and schools of fish, especially when positioned to include the striking granite backdrops. External strobes are highly recommended to bring out the vibrant colors of the hard and soft corals. Macro enthusiasts will find a macro lens perfect for detailing smaller inhabitants like nudibranchs, lionfish, and various invertebrates within the reef's nooks. The stable environment allows for precise focusing and composition. Divers should maintain excellent buoyancy control to avoid disturbing the delicate coral and stirring up sediment, ensuring clear shots and preserving the reef.
