Travel out into the seas offshore to watch the colorful Kona sunset, then jump in to swim with the docile rays as they feed on microscopic plankton. Follow your guides around the manta habitat and watch as the animals are attracted to the bright lights, creating a "manta rave" of lights, bubbles and mantas. All snorkel equipment, including flotation devices and wet suits, is included. Manta sightings are guaranteed, or you will be given a voucher for another tour.

Return Details

Returns to original departure point
Make your way to the tour offices on Honokohau Harbor in Kona, where you'll check in and get fitted for gear. Hop on your tour boat and head out to sea; your spacious vessel is equipped with a top observation deck, a large cabin, and an onboard bathroom.

Reach your destination in time to watch the colorful Kona sunset from the boat's top deck, then start getting ready for your manta ray encounter. Slip into your wetsuit, don your snorkel, and jump in. Buoy yourself with a flotation device; your guides will set up lights to see the mantas clearly. 

Spend about 45 minutes snorkeling using a customized light board with one of the brightest lights in the water, showcasing the graceful ballet of the giant mantas as they careen through the water in search of food. You'll be in 30 to 35 feet (9 to 10 meters) of water, within sight of the shoreline, and supervised by your experienced guide to ensure your comfort and safety. Manta rays have no barbs or teeth, a wing span of 4 to 12 feet (1 to 4 meters) and weigh between 400 and 1200 lbs (180 and 545 kg). Interactions with the manta rays take place in a passive, respectful manner. 

Manta sightings are guaranteed, or you will be given a voucher for another tour.

It was ok. And then I was blasted with emails everyday asking me to rate it and completely ruined my experience which wasn’t amazing to start with so cool
Awesome crew, but they might not have the best equipment
, Jan 2020
We were taken to Garden eel Cove, a far off location (45 minute boat ride) from the launch point, instead of Sheraton (where most Mantas hang out), and the reason they stated was that the water is choppy near Sheraton. However, we only ended up seeing 4 or 5 Mantas, mostly them gliding across. Partly it could be our fault, for having many amateur swimmers, because you have to keep your legs flat so that Mantas come close to you. If they see feet hanging in the water, they might swim away, to avoid getting kicked. That being said, some of the Mantas we saw were massive, and it was a unique experience. Special kudos to the guides and other tourists who helped out my wife continuously, making her feel comfortable in an otherwise scary dark ocean. We will definitely recommend this tour as it is a one of a kind experience.

Saw many manta Rays. Brian was excellent and his bubbles were beautiful. We were extremely lucky seeing these graceful creatures and many fish.
Birthday Swim!

Did this for my 62nd birthday - was excellent!! A little difficult getting back in the boat after as sea was a bit rough, but overall a great time.
Guaranteed indeed

Boat is amazing, the crew were charming and very very helpful and kind. Exhilarating boatride followed by plenty of time in the water, with help and good instructions, followed by another exhilarating boatride back (in pitch black darkness). Well worth a visit
Amazing Experience With Amazing Guides!
, Jul 2019
I really enjoyed this experience. It was executed very well and the guides were very personable talking to various customers on board. They would go under the water and check out the feed and help point out some of the rays. They set us up nicely and helped me out with equipment. I would definitely recommend this to anyone!

'Painful' experience (Disappointed!)
, Jun 2019
We went out last night, via the Bite Me boat tour vendor, to see manta rays. Unfortunately, our boat was the last one to enter the area to see the mantas. By the time we were in the water, we saw ONE manta, and then everything went to hell in a hand basket. Everyone in our boat group was stung by Man O'War jelly fish. All we heard was screaming ask people were getting stung. We heard children screaming and crying, as they were stung. Several of us were stung multiple times, before the crew finally suggested we head back to the boat. My partner and I were at the point to just swim to another nearby boat (any boat that was actually anchored), as it was taking forever for our boat to return to us, to get us out of the water. It took forever until we were back on the boat, at which time we realized how badly most of our group was stung. My partner and I had to go to a Grocery store to buy vinegar, as the captain told us that vinegar helps tame the sting. They also said the pain would only last an hour, however, that is not the case because my partner is still in pain from where her entire wrist and forearm were stung last night, nearly 12 hours ago. The Captain told everyone to call the Bite Me office at 10am, when they open. I called them at 10am, and they said it was at our own risk to go in the water, and they refused to refund any of our money. She offered us another trip out to sea, but we refused. We didn't want to risk enduring such an awful/painful excursion again. We are very disappointed in how things were handled last night. If our boat were anchored the same way all the other surrounding boats were, we would have been back on the boat much sooner, with less stings. Before you decide to take this adventure, please consider that this could also happen to you.
Night Manta Ray Snorkel

This was a good excursion for a reasonable price. However, we weren't actually in the water very long which was a little disappointing. I would have liked to have known a little more about the rays themselves also.
Not as described

We went on the guaranteed Manta Ray Night Snorkel and it was not as described in the advertisement. Here is what was in the description: 2.5-hour nighttime swim with manta rays Learn about the biology and behavior of these gentle, graceful giants Supervised by expert diving guides Wet suite, snorkel gear, and flotation devices provided Watch the Kona sunset from the deck of the boat First you don't really swim with the Manta Rays (if you see one). You hold on to a large rectangular pvc pipe thing and look down. Second the only thing we learned is that Manta Rays have a thin coating or film on their bodies and if you touch them it does damage. Third wet suits is a loose term . Not wet suits but wet tops are provided. Fourth is one of the most disappointing. You should be able to watch the sunset like it says but when the sun was getting ready for it's setting , they turn the boat so that you can't see it. The crew is disappointing. Two young girls with very revealing swimsuits got on the boat and the crew immediately had a special spot for them to sit during the boat ride and spent a good portion of the time with them and then when the boat stopped at the manta spot, these two girls go ahead and jump in the water before anyone and go for a swim. Keep in mind we are all told we can't go out on our own according to coast guard rules. No life vest, no nothing and they aren't holding on the PVC pipe (the PVC pipe wasn't in the water yet) that we all were required to hold on to. The crew does take time though to cast a line for fishing while on the tour. We technically seen a manta even though it was very quick and you could only see a portion of the manta. I would do another night snorkel but with another company if I go back to Hawaii. They did sing happy birthday to one of the people in our party so that was nice.

We had a great time, so glad we decided to do this. I would recommend to anyone looking for a night time excursion. The crew was a lot of fun.
