Why dive here
With 190+ marine species recorded in the area - including blacktip reef sharks, grey reef sharks, sperm whales, thresher sharks and lionfish - Reef Patch offers some of Christmas Island (Kiritimati)'s richest reef diving. Water ranges 27-29°C, warmest June, July, August.
Reef Patch isn't just a dive site; it’s where Christmas Island shows off. We love it because it’s consistently productive, always delivering something interesting. Drop down and you're immediately in a bustling neighbourhood of Coral Blennies peering from every nook, and Greensnout Parrotfish munching through the coral with their rhythmic crunch. It’s not about huge pelagics here, though a Gray Reef Shark often cruises the deeper edge. Instead, it’s a masterclass in reef ecology. Keep an eye out for the smaller stuff – Lemon Peel Angelfish are everywhere, their vivid yellow a real pop against the deeper blues. Our favourite moments are often spent watching a pair of Desjardin's Sailfin Tangs doing their elaborate dance. The currents can be playful, so go with a dive guide who knows the topography well, they’ll show you the best spots to tuck in and just observe. Reef Patch suits divers who enjoy slowing down, taking photographs, and appreciating the intricate beauty of a healthy, busy reef.
