from Night Manta Swim
Join us for our 1-hour evening boat trip out of Keauhou Harbor to snorkel with manta rays just off the Big Island. This quick nighttime snorkeling excursion is a must-do on Hawaii!

Slide into the alluring Pacific Ocean, buoyed by our light board accompanied by our dive guide to witness the majestic manta rays come to fee on the abundant buffet of phytoplankton that appears with the glow of underwater dive lights. Experience the thrill of having giant manta rays gracefully glide and swoop through the waters... all within inches of you.

On the rare occasion, you don't see any Manta Rays, you can join with us again for free on the next available scheduled tour (pending space availability).
