Manta Guarantee Policy

Smaller Group Size
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.

Every tour includes a licensed captain, swim guide, and certified lifeguard to keep you safe and informed.
Water time is approximately 20 to 40 minutes

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.

5.00This is our second time to the Big Island and second time doing the manta rays swim. Deavon was outstanding pushing our booking back when we were delayed. His communication and reassurances were appreciated. The crew- Captain Rory, merman Eric and first mate Kalakala assured us a wonderful, memorable and safe experience! When we return in 2026, it's a given we will book a third time!

5.00I brought two of my adult children, my husband and myself. We had an incredible experience! I was quite nervous before starting, but it was truly wonderful, and I had nothing to fear. Our staff was fantastic and still had lots of energy even being the last group of the night! We had manta rays skimming us multiple times. My family all really loved this. Tips I wanted to know: you truly need nothing except your swimsuit, sandals, and perhaps a waterproof camera. I brought a towel, but it was stored, and I only had it back after disembarking at the boat ramp. I did get cold but toughed it out without a wet suit. No one else in my family felt cold. Parking was easy for the late time slot. Check-in went per the instructions. We were sent a text 3 hours before our scheduled time that we had been moved up 1 hour 20 minutes. It was plenty of time to get there from Waikola Village, but we gave ourselves a few free hours ahead, so not a problem.
Crew was very friendly...

5.00We had the most amazing experience. Jake, Rory and Kalayla (hopefully I am spelling this right) were amazing. We saw 8 Manta Rays and tons of other sea life. Kalayla shared some super cool facts. We had a group of 9. Our youngest was 10 and we all felt safe and had a blast. I most definitely recommend this company. Thank you guys for such an awesome experience.

5.00It is. Magical and surreal adventure. These gental giants are so graceful and beautiful. We loved this adventure. The “Mermaid” gave a wonderful description of the manta rays. Are only concern was that the children were not following the rules, keeping their legs up and their arms straight. It really diverted our attention from the manta rays. It would be nice to have an adult only boat.
It was an amazing...
