    Ngatangiia School might sound like an odd name for a dive site, but it’s one of our favourite spots on Rarotonga's south side, especially if you’re looking for a relaxed wall dive that still delivers on the fish front. We’re talking a gentle slope that drops from around 15 metres down to 20, making it very approachable for anyone comfortable with a bit of depth. The reef here, while showing some past cyclone scars, has bounced back nicely, draped in corals that sway with the gentle surge. What we really love here are the smaller details. Keep your eyes peeled for the resident Spotted Hawkfish perched on coral heads, and we always spot a few Coral Blennies darting amongst the crevices. The schools of Blackstriped Cardinalfish can be quite dense, sometimes seeming to shimmer as they move. We’ve had some cracking encounters with Achilles Tangs here too, their vibrant orange spots a flash against the blue. While the deeper swim-through is beyond our 20m limit here, the shallower sections are packed with enough to hold your attention. We find this site is best in the morning before any afternoon chop picks up, with visibility often stretching to a generous 30 metres, giving you that classic Raro wide-angle view.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
