The Runway

Hundreds of hammerheads in the blue in April and May

The Runway sits between the atoll's two channels and is dived along a wall covered in hard and soft coral at 10 to 25 m. Whitetip reef sharks and the bigger grey reef sharks patrol and hunt the site, dogtooth tuna and barracuda work the same edge, and a manta ray sometimes drops in for a look.

The dive

You start on the reef and follow it in the 10 to 25 m band, keeping the wall on one shoulder. Current is typically moderate, so the coral passes at a steady pace and the shallow profile leaves room for a long dive. The reef is only the reference, though: the reason to be here is the open water off it, so most of the dive is spent looking out rather than down.

Reef sharks are the constant, with whitetip reef sharks and the bigger grey reef sharks patrolling and hunting the area. Dogtooth tuna and barracuda pass along the same edge, and a manta ray occasionally comes in to say hello. In the right season, April and May, hundreds of hammerheads can school in the blue all around you.

When are the hammerheads at The Runway?+

April and May are the months called out for schooling hammerheads here, when hundreds can pass in the blue. Reef sharks, dogtooth tuna and barracuda are around outside that window.
