The Kona Coast has become known as one of the best Manta Ray encounter sites in the world and has become a very popular activity on the Kona side of the Big Island. Manta Rays are attracted to diver's lights and come to feed on plankton. Divers typically stay on the bottom and snorkelers on the surface so as not to disturb the mantas. Mantas range in size from 8-15 feet long and from 12 to over 20 feet wide. Up to 30 mantas may come to feed at a time, making for quite a sight.
There are many snorkel and scuba related businesses that offer Manta tours as a part of their activities. In addition to the boats listed here, some companies listed on our scuba and snorkel pages also offer a manta dive. Whomever you go with, make sure not to miss this one of a kind experience.
