Our custom light boards use over 150,000 lumens of blue dive light, attracting more plankton and increasing your chances of manta sightings.*

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.

5.00It was very good, we saw a lot of manta rays, and the people were nice. I would suggest doing it later as we were told there are even more manta rays then.
Manta rays!!!

5.00I was a little nervous when I had a difficult time filling out the waivers. But the experience itself was amazing. The team was organized, experienced and a good time. The manta rays were so beautiful. Loved it!
Close encounters!

5.00Amazing experience with manta rays doing somersaults in the water and swimming by inches away from your face. Highly recommend!

5.00Kinda chilly so if you have a wetsuit top, bring that. We saw 8 manta rays and they come right up to you. Cool experience. I saw some other tour companies offering 2 hr tours, that’s too long. 1 he is the perfect length.

5.00Manta rays are such beautiful creatures! This snorkeling adventure lets you get so close to such majestic creatures that literally swim right beneath you and as close to your face as you can imagine. This activity is the most “must do” thing on the Big Island in Kona!

5.00What a great way to spend New Year's Eve with my boys. It was a great experience and I would for sure do it again. We saw 3 rays up close. Crew did a great job at making us feel comfortable. You cannot bring anything on the boat, but can bring a towel and small bag to leave at van. Highly recommend.
Good experience with a criticism

4.00The walk is very good. Although we have only seen one rainbow, it has surrounded us all the time. The criticism is the rough treatment by Deavon at check-in. When we finished the tour and went to return the jackets, he apologized to us, but he kept being rude.
Amazing Experience

5.00This was an amazing experience! We saw three manta rays and they came so close to us. We rented wetsuits and a GoPro. The GoPro was a great idea because we have videos of these beautiful creatures doing flips right in front of us. We highly recommend this tour!

5.00The crew was very prepared and the check-in/boarding process was seamless. The positive attitudes from the whole team really set the tone for the awesome experience once we were in the water. I would definitely do this again.
Amazing views of Manta Rays and an even better once-in-a -lifetime experience!

5.00This experience was so spectacular for my family and provided such a unique nature outlook we will carry for the rest of our lives! The guides were very knowledgeable and clued us in on all things manta ray. This was a great way to spend our Christmas Day night and we highly recommend it!
