Kona Night Scuba Dive with Manta Rays

Location: Kona, Big Island

Mark an item off your bucket list and join us for an incredible encounter with the Kona Manta Rays at night. This world famous dive / snorkel trip has been featured on numerous Travel, National Geographic and Discovery Channel programs.

The Hawaiian Kona Coast is home to over 240 resident Manta Rays and each has been identified and named. Much like a fingerprint is unique to each human, Manta Rays have distinguishing black and white markings on their underside that are used to identify them nightly. These gentle giants can grow up to 16 feet in length and weigh up to 1600 pounds, but they have nothing that bites or stings, making this the safest large animal encounter in the world. Groups of Manta Rays converge nightly off of Keahole Bay to feed on the smorgasbord of phytoplankton that appear to soak up the glow given off by underwater dive lights.

Enjoy a scenic sunset boat ride along the Kona coast to the manta location. Our friendly and knowledgeable staff will instruct you on how to encounter these amazing creatures so we can protect the mantas and their habitat. In a water depth of about 30-40 feet, both snorkelers and certified scuba divers are able to safely view the incredible performance by the manta rays. Mantas "Lefty," "Koie," "Blain," "Big Bertha," "Darth Ray-dar," and more put on a show for you.
