Avoid the crowds—our tours are limited to a small group of 17 or fewer, unlike big boats that carry up to 50 guests.
Shorter Boat Ride
Get to the action faster with a quick 3-minute ride to the manta site—no long 30-minute boat ride like other operators.
Unmatched Light Power
Our custom light boards use over 150,000 lumens of blue dive light, attracting more plankton and increasing your chances of manta sightings.*
(*Mantas are wild animals—sightings are common but not guaranteed.)
Statistically Better Later Tours
Later tours often have fewer boats and more manta activity, enhancing your experience.

What To Expect
Manta guarantee policy, if you don’t see them come again Free! Manta Ray Night Snorkel in Kona! After a 3 minute boat ride from the harbor, you’ll enter the water and float on the surface while holding onto our custom-built light board. The powerful 150,000+ lumen dive lights attract plankton, which in turn draw in majestic manta rays that glide and feed just inches below you. It’s a breathtaking, up-close experience guided by our professional team, including a licensed captain, swim guide, and certified lifeguard. Water time is approximately 20 to 40 minutes depending on various situations ocean conditions, etc. *Statistically the later at night you go the more manta rays and the more time we have the manta rays increases significantly! The earlier you go, very crowded, making it harder to get manta rays must know how to swim and be comfortable in open ocean conditions. Wetsuits & lifejackets are optional rentals and can be arranged. Free masks and snorkels are provided, or you may bring your own.

1.00The one star is for the check in guy. His attitude was terrible. If you are having a bad day, you should stay home, not come to work and ruin other people's vacation. At the end he even told us “we’re a small family owned business, it’s not easy” for what? We also didn’t have it easy flying all the way to the Big Island just to experience this tour. The tour was delayed and they even tried to cancel us last minute. Luckily, we weren’t canceled, but the time in the water was very short, only about 15 minutes. I understand the time is not guaranteed, but 15 minutes is definitely not what we expected. Overall, not recommended. Terrible service and disappointing experience.
Incredible experience! We...
