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.

5.00We are a family of 5 and had the best time! The staff was fun and patient. We saw 3 huge manta rays on our 20 min in the water. We would definitely do it again on our next trip to the Big island.
Unreal experience!!

5.00Absolutely amazing, the crew was so friendly, and knowledgeable, they knew where the manta rays would be ( basically manta whisperers) they made it feel super safe and so enjoyable, the manta rays get so close and it’s crazy to see them doing backflips and eating the plankton. 10/10 recommended and definitely a must do on Kona!
Great experience

5.00This is the most amazing thing i have ever done. The rays look beautiful. If you paid $10.00 you could get a wetsuit, I would recommend it. The staff was perfect, very honest and friendly, but also professional and productive. They knew even the names of the rays! Their names were Jake, Dave, Devin. we had 16 or 15 people in our boat. It took about 30-40 minutes to watch the rays. 5 to get out there. There is no “best for”, I would recommend it to anyone.
WORTH IT !!

5.00Incredible trip!! The guys were amazing! We saw 8 mantas and had the best time! Best boat to take out! Totally worth the trip, no experience like swimming with the mantas at night!
10/10 experience. Saw a lot of manta rays up close!

5.00Absolutely amazing experience. 10/10 would go again. Everyone was great and made sure the experience was top tier. We got to see a few manta ray and one super close I’m surprised it didn’t touch us! If you’re on the fence about going- definitely book it and go!
Wasted vacation on getting in contact with this company

1.00I cannot recommend booking a Manta Ray night snorkeling tour through this company due to extremely poor customer service and misleading information. My friend and I purchased vouchers for the tour, which we later discovered could only be redeemed for the 11:00 pm tour—something that was not made clear at the time of purchase. We spent two full days trying to contact the company by phone to book a time slot, but no one answered and calls consistently went to voicemail. Since the tours appeared to have plenty of availability online and the company has no physical office, we decided to show up in person at one of the tours. When we arrived, we were told to leave in an unpleasant and dismissive manner, likely because the staff were stressed and running late. Frustrated by the complete lack of support, we waited until the tour had departed to speak with someone. We were then told that we could not be added to any tour, despite there clearly being available space. Instead, we were given another phone number to call—which, unsurprisingly, went straight to voicemail. The following morning, we finally managed to reach someone and were booked onto the 11:00 pm tour, with the agreement that we could call back at 5:00 pm to try to move to an earlier time. When we called back as agreed, no one answered. An hour later, we reached another staff member who told us their system was down and that switching to an earlier tour was impossible. Then, half an hour later, we were contacted again and suddenly placed on an earlier tour after all. From that point onward, the tour itself went relatively smoothly. However, we were only in the water for about 15–20 minutes, despite the company advertising 30–40 minutes on their website. Overall, we spent the majority of our three days in Kona simply trying to get in touch with this company, which was a huge waste of valuable vacation time. Until they significantly improve their customer service, communication, and transparency, I would not trust booking anything through them.
Once in a life time experience

5.00Our family had the most amazing experience with this tour group! Deavon started the night sharing his knowledge, expertise and details of what to expect on this tour. He was very funny and knowledgeable. The water was a little rough the night we went but David, Jasmine, and Greg are very experienced and made us more than comfortable. Greg was an amazing leader in the water with us. He worked overtime to swim us around and ensure we had the viewing of a lifetime. We saw 2 large Manta Ray and a couple babies that swam around our board almost the entire time. Best experience, highly recommend for all ages!! Thank you for the best adventure!
For the people, and the mantas

5.00I couldn’t believe how awesome the team was, they took care of us and we were troublesome… we missed our booking, I was super dehydrated and the gentleman running it made sure we got on a later tour that day… gave me his personal coconut water to look after me, and made sure we had wetsuits… It’s that kind of above and beyond the employees show for the individual, even though they see hundreds of people a day, that really sets this business apart. 10000 percent recommend it, and the mantas were insane!!!
