Experience an extraordinary Manta Ray Night Snorkel in Kona, one of the few places worldwide where you can swim with manta rays after dark! Following a brief 4–5 minute boat ride from the harbor, you’ll enter the water and float on the surface while holding onto our specially designed light board. The powerful dive lights, exceeding 150,000 lumens, attract plankton, which in turn draw in the magnificent manta rays that glide and feed just inches below you. This is a breathtaking, close-up encounter led by our professional team, including a licensed captain, swim guide, and certified lifeguard.

All participants must be able to swim and feel comfortable in open ocean conditions. Wetsuits and lifejackets are available for optional rental and can be arranged during check-in at our BIO storefront. Snorkel masks are provided, or you may bring your own. If manta rays are not spotted, Viator bookings are eligible for complimentary rebooking (subject to availability). Please be aware that delays may occur due to wildlife activity, weather, or dock traffic.

Smaller Group Size

Steer clear of the crowds—our tours are limited to a small group of 17 or fewer, unlike larger boats that accommodate up to 50 guests.

Shorter Boat Ride

Reach the action swiftly with a brief 3-minute ride to the manta site—no lengthy 30-minute boat rides like other operators.

Unmatched Light Power

Our custom light boards emit over 150,000 lumens of blue dive light, drawing in more plankton and boosting your chances of seeing mantas.
