    CharacterReef dive

    Hanauma Bay is a good spot for an easy shore dive, especially if you’re new to the ocean or haven't dived in a while. The calm, shallow waters make it ideal for regaining confidence, though it can get pretty busy with snorkelers. We’ve spotted plenty of reef fish here: parrotfish, surgeonfish, and sometimes a green sea turtle gliding through the coral patches. It’s not a deep dive, more of a relaxing swim-through.
