Float above a column of light as manta rays loop and feed beneath you on the Kona coast. This 2.5-hour night snorkel pairs easy-entry ocean conditions with one of the planet’s most reliable manta ray encounters.
More ways to explore the area's outdoor wonders
The sky over Kona blackens and the shoreline lights blink like small beacons as the boat slips away from Honokohau Harbor. You enter the ocean at dusk, anchored above a dark floor while powerful spotlights draw a cloud of plankton upward — and the mantas arrive. They move like living sails, turning and somersaulting through the illuminated column, mouths open to filter tiny prey as you float on the surface or, for certified divers, kneel on the sandy bottom with lights above.

Book for moon phase and weather
Visibility and manta activity can be affected by moonlight and wind; choose a new-moon or low-moon night for darker skies and stronger plankton attraction.
Wear a snug mask and fins
A well-fitting mask and comfortable fins reduce fatigue during surface-floating and help you track mantas without constantly surfacing.
Use reef-safe sunscreen only
Apply mineral-based, reef-safe sunscreen before arrival to protect coral and marine life; don’t apply in the water.
Tell guides about health and weight
Operators ask for height/weight and medical info—be transparent so they can provide correct equipment, flotation and safety measures.
Well-fitting snorkel mask
A leak-free mask improves your view and keeps you relaxed during prolonged surface time.
Reef-safe sunscreen
Protects skin while preventing chemical damage to coral and marine life.
summer
Short wetsuit or neoprene top
Keeps you comfortable in cooler evenings or for longer surface sessions.
winter
Waterproof headlamp or small flashlight
Useful on the dock and for gear checks; guides provide primary lights for the manta display.
