Site details

The Big Island's most famous shore dive, named for the natural two-step lava ledge entry beside the Honaunau boat ramp, next to Pu'uhonua o Honaunau (Place of Refuge) National Historical Park. A shallow coral shelf drops quickly down a steep slope to sand at about 100 ft, with superb hard coral and frequent spinner dolphins in the bay. Beginner-friendly in the shallows but easy to get deep.
