STANLEY ISLAND - Goat Island & Hauraki Gulf

Two Ridges is one of those sites that proves you don't need huge depths to find something special. We love it because it’s a wreck, but not in the traditional sense. Here, two massive coral outcrops, some say they resemble an upside-down catamaran hull, have created a unique habitat. You’ll weave through those impressive coral structures, eyes peeled for the resident thresher shark that hangs out deeper, though seeing it takes some luck and a good guide. Visibility here often hits 25m, making those deep blue drop-offs to the wall quite dramatic. Keep an eye out for mantas gliding by. Closer to the "wreck," the corals are busy with parrotfish crunching away, and we always spot a few playful clown tangs. This site is a great pick if you enjoy exploring interesting reef formations with a side of pelagic possibility, and it’s manageable for most divers.
