Calalin Channel - Majuro Atoll
Calalin Channel isn’t for the faint of heart, but if you’re an experienced diver who loves a good drift, this is your spot. We love the sheer energy of it, the feeling of being propelled through the water, with the current doing all the work. You’ll drop in, usually with a fair bit of surge, then the channel just sucks you in, pushing you along past walls of hard coral. Keep your eyes peeled for grey reef sharks cruising through the blue – we’ve seen them in decent numbers here, sometimes a dozen or more. Eagle rays are a common sight too, gliding by with that effortless grace. The whole dive is a wild ride, from 10m down to around 30m, and it finishes out on the reef flats. Our favorite part is when you hit the slightly calmer areas, you can really take in the smaller details: the vibrant parrotfish, those big blackfin barracuda hanging motionless, and occasionally a curious polkadot cod peeking from a crevice. It’s an advanced dive, definitely, and you need to be comfortable with strong currents, but for that exhilarating rush and the chance to see some serious pelagics, it’s worth every bit of effort.
