Avaavaroa Drop Off - Rarotonga

Avaavaroa Drop Off is one of those sites we always recommend. You start by finning through sand channels, the kind that feel almost manicured, coral walls rising up on either side, then it just… drops. Not a gradual slope, but a proper edge into the blue. We love hovering right on that precipice, watching the reef fish like four-spot butterflies and orange-axil wrasse dart in and out of the staghorn coral, then just tilting your head to scan the open water. That’s where the real magic happens. This is our pick for pelagic sightings. We’ve seen everything from schooling tuna flashing past in the current to eagle rays gliding by with that effortless grace. There’s always a chance for something bigger, too. If you’re lucky, you might even spot a tiger or hammerhead, though we think the real treat here is the sheer drop-off itself, the way the light changes as you look out into the deep. Visibility here is often well over 20 metres, so you get that incredible sense of scale. It’s a site that rewards patience, perfect for those who enjoy scanning the horizon as much as poking around the reef.
