    StandoutExceptional marine biodiversity

    The Swarm often delivers on its name, with dense schools of fusiliers and anthias creating a shifting curtain of fish. We've finned through them so thick you lose sight of your buddy. Look closer on the reef for Blackbelly Pygmygobies and Sparse Eviotas. It’s a good spot for wide-angle photographers and divers who appreciate sheer numbers.

    Safety Notes
