The topography offers a protected profile suitable for gentle exploration, with shallow coral gardens along the crest transitioning into sandy channels where bottom-dwelling species rest.
Network of coral bommies covered in soft corals and sea fans
Frequent encounters with resting whitetip reef sharks along the sandy floor
Vibrant shallow reef top featuring giant clams and schools of damselfish
