Why dive here
With 163+ marine species recorded in the area - including blue sharks, blue whales, dolphins, great white sharks and hammerhead sharks - Hole in the Rock offers some of Bay of Islands's richest cave diving. Water ranges 16-22°C, warmest January, February, March.
Diving the Hole in the Rock is mostly about the structure itself. You descend along the rocky walls, exploring crevices where we've often spotted crayfish and moray eels. It’s a pretty straightforward dive, great for anyone who enjoys interesting topography and a bit of a current push through the archway itself. Visibility can vary, but on a good day, the light filtering through the "hole" is quite something.
