Aroa Rā’ui - Rarotonga

Citrus Ridge, about an hour's boat ride from a good handful of dive resorts in Raja Ampat, lives up to its name thanks to those bright yellow corals that catch the light. It's not the deepest site, topping out at 23m, but it’s a good spot for keeping your eyes peeled. We've seen everything from Denise's pygmy seahorses camouflaged on gorgonians to reef manta rays cruising by. Look for wobbegong sharks tucked under ledges and keep an eye on the seagrass beds, where Olive Ridley and Leatherback turtles are sometimes found. Visibility usually sits around 18m, which makes it a comfortable dive for anyone who enjoys a mix of macro life and the occasional big visitor.
