The Hawaiian Kona Coast is home to over 200 resident Manta Rays and each has been identified and named. Much like a fingerprint is unique to each human, Manta Rays have distinguishing black and white markings on their underside that are used to identify them nightly. These gentle giants can grow up to 20 feet in length and weigh up to 3000 pounds, but they have nothing that bites or stings, making this the safest large animal encounter in the world. Groups of Manta Rays converge nightly off of Keahole Bay to feed on the smorgasbord of phytoplankton that appear to soak up the glow given off by underwater dive lights.

Enjoy a scenic sunset boat ride along the Kona coast to the manta location. Our friendly and knowledgeable staff will instruct you on how to encounter these amazing creatures so we can protect the mantas and their habitat. In a water depth of about 25-30 feet, both snorkelers and certified scuba divers are able to safely view the incredible performance by the manta rays. Mantas "Delaney," "Koie," "Blain," "Big Bertha," "Darth Ray-dar," and more put on a show for you.

Meet these majestic creatures face-to-face with our experienced staff to guide you!

Frequently Asked Questions
Click on the red "Book It" button and you will see live availability. Keep in mind availability changes constantly, so make sure to book in advance!
H Tours Hawaii is a "one stop shop" for all the best activities in the Hawaiian Islands. Since we work with many providers, reservations are necessary. WE HIGHLY recommend making reservations, as many activities are at a discount when you reserve in advance. Some providers even charge higher for those "walking in" because they know chances are you're not going to walk away. Finally, a reservation ensures you have a space on the tour. Trust us you don't want to spend so much time and money to come to Hawaii and then miss out on an activity because they were booked out!
Choose the tour you are interested in, click the red “Book It” button adjacent to the tour information, and complete the booking form.
Most companies, if not all, require you to call them if you're trying to book something 2-3 days in advance. Do you really want to be spending your valuable time in Hawaii calling around to desperately find something that is available to do? While we can usually accommodate most last-minute bookings, we highly encourage those that are checking out our website far in advance to book 2-3 weeks prior to desired date. You never know if there's a convention, special event, or an increase in overall visitors in town, and it would be a shame if the activities that you want to do are sold out because you waited until the last minute. Basically, if you know you want to do it, just book it!
Gratuity is never required but if you enjoyed your experience, a tip is always greatly appreciated!

Shout out to Jim, Dwayne, and Seth!! Thanks for the fun trip. I've done a lot of diving, not as much as some, but more than other; and this was by far the best dive so far!! The Mantas are so peaceful and elegant. They swim so close to you (inches or less) and never touch you. I saw a few run into each other once or twice which was funny. They overweight you as a diver so you can sit on the ocean ... morefloor (no coral) and just chill. Seth knew what he was doing. The crew are very knowledgeable about manta rays and marine life and are not boring at all. They were very entertaining and kind. After the dive there was hot chocolate and snacks. I'd recommend anyone who is on the big island to do the Manta dive/snorkel. 

A hui kaua
Great Manta Ray Dive
Came to the big island especially for the manta ray dive. The whole stuff is very professional, and the gears are good and new.  We left the dock around 5 pm, and came by before 8 pm.  My dive master Chris was awesome, he gave us very informative briefing of manta rays. When guiding us to the spot, he turned his head almost every 10-15 seconds to make sure we were not lost in the dark ocean, and when ... morewe were enjoying the manta ray show at the spot, he helped checking our air and let us watch the manta rays(we saw about 10 of them). 

I will definitely come back and dive with them the next time I visit big island!
A crazy dive experience
I went out with my sister to do the famous Manta Ray night dive. I already did the snorkeling part, and really enjoyed it, so I had high expectations of the dive. I am a pretty inexperienced diver with only 9 past dives, so when I first dove into the black water I was already mind blown. Our divemasters Ken and Seth was really enthusiastic and skilled, and made me feel really comfortable going down ... morethere. The dive lasted almost an hour, and man it was super exciting. I even had a Manta Ray circle above my head until it went so low that it touched my skull. What an experience! Rest of the crew was really nice and I liked being around them. It is a pricy trip, but you will probably have an experience you will never forgot. Gør det gør det gør det;)

Manta Ray snorkel trip
How can I express the excellence of this experience? One word. Magnificent. This experience far exceeded my rather high expectations. Truly an experience of a lifetime to view Manta Rays feeding as close as a few feet away. Not being a diver, I was worried that the views would be suboptimal for snorkelers. I was wrong. The animals are plenty close and visible from the surface. Do not miss this opportunity. ... moreAnd use Neptune Charlie's if you can.
Now the specifics. The slip to Neptune Charlie's is a little difficult to find. Just follow their clear directions. They do not have a storefront. You meet at the boat. From then on, you are well cared for. Colin, our captain, was friendly, entertaining, and made us all feel comfortable even though the seas were marginal (my first reservation was cancelled due to weather but they were very accommodating at rebooking me - I am so glad I did). Colin obviously has experience and I felt he was focused on our safety as his primary goal. The crew (Jeanine and Duane) helped get us orientated on the ride out to the site which is along the coast and not in the open ocean. Then we were fitted for masks, fins, and wetsuits. (I needed a prescription mask and they gladly accommodated that request.) Once the sun sets, it is into the water. Again, I was concerned about whether one could 'float off' in the night. Nothing to worry about. A glow stick was affixed to our masks but we stayed in a group of 8 holding onto a raft and moving about together with the lead of one of the crew in the water with us. Completely safe and secure. 
Then, the fun continues. To watch 1000 pound rays (no stingers, strictly vegetarians) somersault in the water while they feed on plankton was awesome to behold. Do not know if it was an unusual night but there were at least 6 rays at a time and literally a couple of feet from the surface. Simply unbelievable. 
The ride back was filled with excitement as everyone talked about the experience. There are snacks on board and the captain and crew were welcoming, professional, and truly excited about their work. It showed. Neptune Charlie's is a first rate operation.
If you are near Kona, do not miss this opportunity.
