Blue MaoMao Arch - Poor Knights Islands

Dzinani is our go-to when we want a proper drift. It’s got that classic Diani mix of deep coral ridges and stretches of open sand, but here the current often picks up just enough to give you a real ride. We’ve found the best approach is to let yourself go, gliding over the corals, then dipping into those sandy channels where white-tip reef sharks sometimes just rest, unbothered. You'll often see schools of barracuda shimmering in the blue, or giant trevallies tearing through smaller fish. Visibility here can sometimes be a bit variable, averaging 13m, but when it’s good, the light plays beautifully through the water, making the corals glow. We’d suggest this one for divers comfortable with a bit of pace, it’s not for faffing about.
