    CharacterWreck dive

    Kona diving is all about those volcanic surprises and the critters that have made them home. We particularly love exploring the lava tubes and grottos here; they’re a cool contrast to the open reef, offering up a bit of an architectural feel to the dive. Inside, look for the blackside hawkfish perched on ledges and the blotcheye soldierfish tucked away. The shallower max depth of 18m means plenty of bottom time, which we appreciate for really soaking in the details. You’ll find schools of sleek unicornfish zipping by, and if you’re lucky, a whale shark might cruise through, a real contrast to the smaller inhabitants like the regal parrotfish munching on coral. We’d suggest keeping an eye out for nudibranchs on the rock walls, too. Kona is a great choice for divers who enjoy a mix of unique topography and a comfortable pace.

    Safety Notes
