Kona's famed Manta Night Dive is the mother of all night dives. Divers are arrayed in a circle at Garden Eel Cove and off Kona's Keauhou Sheraton pretty much every evening, lights pointed skyward, with additional banks of overhead lights supplied by operators. Mantas come swooping in, standing on their heads — and yours — in an explosive sensory overload. The key? The lights. The better the light, the more plankton is attracted, and the more manta action for that diver.
