Diving in Cook Islands

Rarotonga

Rarotonga isn't your typical Pacific dive destination, and that’s precisely why we love it. Forget crowded boats and dive sites. Here, you'll often have the reef to yourself, which feels like a real privilege. Diving largely revolves around the reef passages, intricate cave systems, and dramatic drop-offs just outside the main lagoon. We’re not going to lie, the visibility can be a bit variable, depending on the currents and recent rainfall, but when it’s good, it’s spectacular - a vibrant blue that just swallows you whole. Our favourite dives are often the drift through a passage, where you can watch parrotfish grazing on the coral and see schools of blackspot surgeonfish darting by. Keep an eye out for the more unusual residents too, like the ornate Pacific cornetfish or the surprisingly common porous cowries tucked away in crevices. Some of the outer walls hold a nice population of horned bannerfish, their long dorsal fins trailing elegantly in the current. If you're into macro, the caves are fun for spotting Isabel's hermit crabs. The currents can get strong, especially near the passes, so it’s definitely one for the intermediate to advanced diver who enjoys a bit of movement.
