Christmas Island, out in the Indian Ocean, is a place that feels genuinely remote. We love a good wall dive, and these aren’t just any walls. They drop sharply, often to absurd depths, straight into the abyss. It’s where you’ll often find yourself eye-to-eye with a Gray Reef Shark patrolling the blue, or just hanging out watching the thermocline ripple past. The real magic here, though, is the sheer scale. We’ve seen whale sharks cruise by so close you could feel the displacement of water, and manta rays glide past like silent alien spacecraft. The reefs themselves are a healthy mix of Staghorn and Montipora corals, often punctuated by enormous Corrugated corals that just demand a closer look. Our favourite is spotting the Desjardin's Sailfin Tangs, their dorsal fins almost comically large as they nibble at the reef. Keep an eye out for the smaller stuff too, like the vibrant Zebra Blenny popping out of its hole. Current can be a factor, so be prepared for some serious drift dives along those incredible walls.
