Night Diving with Giant Manta Rays in Kona, Hawaii
This stunning underwater video captures the world-famous Kona manta ray night dive — where reef manta rays up to 5 metres across perform barrel rolls through plankton-lit water directly above kneeling divers.
The night manta ray dive off the Kona Coast of Hawaii's Big Island is consistently ranked among the top ten dives in the world, and this video from AmazingPlanet4U shows exactly why.
The dive site, known as Garden Eel Cove or Manta Heaven, works on a simple ecological principle: lights attract plankton, plankton attract manta rays. Divers and snorkellers kneel on the sandy bottom or float on the surface, each holding a torch pointed upward, creating a column of bioluminescent plankton that draws the mantas into close, repeated feeding passes. The mantas — some with wingspans exceeding 5 metres — loop and barrel roll through the light columns in a choreographed display that is as close to magic as scuba diving gets.
The video captures multiple mantas working the light column simultaneously, including close passes that bring the animals within arm's reach of the divers on the bottom. Reef manta rays (Mobula alfredi) are filter feeders — entirely harmless to divers — and appear remarkably unbothered by the presence of lights and bubbles.
The Kona manta dive is accessible to divers of all experience levels and operates year-round, though sightings are most reliable from May through October when planktonic blooms are strongest. Nearly every dive operator on the Kona Coast offers dedicated manta night dive packages, typically departing at sunset and returning after dark.
For divers planning a Hawaii trip, this dive alone justifies the journey to the Big Island. Combine it with daytime dives on the lava tube systems and open ocean pelagic sites that Kona is also famous for, and you have one of the most varied one-stop dive destinations in the Pacific.
