    StandoutExceptional marine biodiversity

    Moonhole is one of those spots we genuinely look forward to visiting. It’s got a real mellow vibe, a sheltered cove tucked away that means you can usually dive it when other sites are getting blown out. We typically drop in and follow the reef slope down to the sand, usually staying around the 10-12 metre mark. That northern corner can surprise you with a proper washing machine current sometimes, so we tend to keep an eye on it. What makes Moonhole special for us isn't the big pelagics, though you'll always see schools of sennet weaving through the sea plumes. It's the small stuff. We've had dives here where we've spotted half a dozen seahorses, just gently swaying in the soft corals. Keep your eyes peeled on the sand patches too; we often find Sand Stargazers buried there, just their eyes peeking out. You’ll also spot plenty of Harlequin Bass and Mottled Conger Morays tucked into crevices. It’s a site for slowing down, for the macro lovers, and for those who appreciate the subtle beauty of a healthy Caribbean reef.
