Ngatamahine Point - Poor Knights Islands

Rarotonga Bay is a familiar friend for us, a spot we’ve returned to time and again. It’s got a lovely sandy patch at about eight metres, perfect for sorting out buoyancy before you head to the main reef. We love poking around the kelp here, especially in the shallows where the light catches it just right. Keep an eye out for Short-tail Stingrays gliding over the sand, and we’ve often spotted Green Rock Lobsters tucked into crevices. The Common Triplefins are always busy flitting about, and on a good day, the visibility can genuinely surprise you, giving it that almost-tropical feel. It’s a great spot for newer divers, but even experienced eyes will find plenty to keep them occupied, especially if you’re into macro life in the kelp.
