Floating in the dark ocean at night while giant manta rays — some with 12-foot wingspans — glide inches below you, feeding on plankton attracted by underwater lights. It's surreal, humbling, and absolutely unforgettable. This is Big Island's most magical experience, and Manta Ray Dives of Hawaii operates right from Kailua-Kona.
You don't need to be a certified diver — snorkelers float on the surface and get equally incredible views. The mantas are gentle, curious, and completely wild. On good nights, you'll see 20+ rays swooping so close they might brush your head. This family-owned operation keeps groups small (6-8 people max) and prioritizes safety above all — they'll cancel for conditions and rebook you free if needed.
💡 Insider Tip
Book with Manta Ray Dives of Hawaii for the small group experience — reviewers rave about guides like Justin, Ty, and Kenny. Take Dramamine an hour before since night waters can be choppy.
