Discovering Kona’s Night Manta Snorkel Experience

Imagine the quiet of Kona’s shores at dusk, the sun dipping into the ocean, and then stepping into the water to find elegant manta rays gliding effortlessly around you. That’s what this tour promises: an intimate, awe-inspiring encounter with some of the ocean’s most gentle giants. The tour departs from the address at 247 Kealakehe Pkwy, making it easily accessible right from Kona’s tourist hub.
The journey begins with the crew passing out top-tier wetsuit tops, masks, snorkels, fins, and float belts. These details are important—reviews note the high-quality gear that keeps you warm and comfortable during the swim. The boat then cruises along Kona’s shoreline toward one of two manta-ray hotspots, depending on the best conditions that night.
One of the tour’s biggest strengths is the LED light boards. These tiny but powerful lights illuminate the water, attracting plankton, which in turn draws in the mantas. It’s a spectacular display of nature’s choreography—these rays are graceful and curious, often swimming beneath and around snorkelers. As Mary_H put it, “There are no words to describe this incredible experience! Honestly, we were a little scared of snorkeling in open water at night with manta rays, but I will absolutely be doing this again. The manta rays were stunning! Such graceful and beautiful creatures.”
Another highlight is the small group size—up to 26 travelers—which ensures guides can give personalized attention. Guides like Tim are praised for their knowledge and kindness, helping with gear, explaining manta behaviors, and making sure everyone feels safe. Jackie_C noted, “The crew was fabulously kind and communicative. They helped prepare our wetsuit and snorkel equipment. They discussed with intimate knowledge the nature of the mantas. They helped us into the water and did all the work while we just enjoyed the show.”
