A manta ray night snorkel is a guided ocean experience where guests float at the water's surface after dark while powerful underwater lights attract plankton — drawing in Pacific manta rays to feed directly below. In Kona, Hawaii, this experience takes place at one of the Big Island's most reliable manta ray gathering spots, where sightings are consistently high due to the unique combination of calm waters, nutrient-rich currents, and established feeding behavior. Mid-Pacific Tours leads this experience in small groups of no more than 6 guests, departing at sunset for a scenic boat ride along the Kona coast before anchoring at the dive site. Once in the water, guests hold onto a floating light board while our guides — in the water alongside you — narrate the encounter and ensure your safety and comfort throughout. The full experience runs approximately 2 to 4 hours, including transit and in-water time.
