Hawaii Island Water Adventures

Double Lines

With more miles of coastline than any other Hawaiian island, the waters of Hawaii Island are a haven for marine life. Shielded from the winds by Maunaloa, the calm and clear waters of Kona are the perfect place to snorkel, scuba dive or go on a manta ray dive at night. These waters are full of sea life from honu (Hawaiian green sea turtles) to deep-sea game fish, which makes Kona such a popular place for sports fishing. Of course you’ll also find kohola or whales that visit every winter, as well as the sperm, pygmies and false killer whales that are here year-round.

If you’re not into kayaking, surfing or parasailing, the beautiful beaches of Hawaii Island are a great place to simply relax and get your feet wet. If you are exploring Hawaii’s underwater world, remember how fragile the ocean environment is and malama kai, or take care of the ocean. More than a quarter of the sea life in Hawaii is found nowhere else on earth so please don’t touch the living coral or the animals and plants surrounding it. Even though the honu look friendly, remember they are an endangered species and touching them could harm them. Have fun in the water, but with all marine life, keep a respectful distance—for their safety and yours.
