About this experience

Swim with Manta Rays After Dark

Few Big Island experiences feel quite like being in the ocean after sunset with manta rays gliding beneath you. Once darkness settles over the Kona Coast, tour boats head to established viewing areas where lights are placed in the water to attract plankton. If the mantas arrive, you may watch them loop, turn, and feed just below the surface, sometimes passing surprisingly close.

Current options include the Ocean Encounters Manta Ray Night Snorkel, Sea Paradise sunset and moonlight manta tours, and Dolphin Discoveries Manta Discovery Adventure. Tours generally run from about 1 to 2.5 hours and may visit areas near Keauhou Bay, Manta Village, or other established Kona Coast viewing sites.

The main difference is usually the timing and pace of the trip. A sunset departure gives you a little daylight on the water before the snorkel begins, while a later moonlight tour keeps the focus on the nighttime experience and may involve less total boat time.

Bring a towel and dry clothes for afterward, and be ready for a bit of waiting once you are in position. Manta rays are wild animals, so sightings are never guaranteed, but that uncertainty is part of what makes the experience feel so special when they do appear.
