Visitors to the Kona Coast of the Big Island have an opportunity to participate in one of the most unique ocean adventures in the world! Manta rays frequent the warm waters of the rocky volcanic coastline in search of plankton, their primary food source. With their giant mouths constantly open, they glide through the water and filter these tiny creatures. There is one particular spot close to the Kona airport where mantas congregate in the early evening, and after dark they are attracted to lights that are placed on the bottom of the ocean in about 30 feet of water. These lights attract clouds of tiny plankton and the plankton attracts the mantas. These giant rays gracefully glide, twirl and do somersaults to swoop up the tiny little food particles, sometimes within a foot or so of the snorkelers! You, too, can witness these spectacular ocean creatures in their magical underwater ballet in an event you’ll never forget!

The manta ray encounters along the Kona coast began back in the early 70’s; a hotel called the “Kona Surf” had bright lights that shined into the ocean and mantas were attracted almost nightly. Scuba operators began doing night dives. While the location gave a reliable chance to see manta rays, the spot was not very protected from ocean swells and sometimes the area would be too rough to dive or snorkel.

In 1999 the Kona Surf Hotel closed and the lights were turned off. The manta rays found a new spot to congregate in a bay near the Kona airport where plankton concentrated in the late afternoon sun. This is the spot where most mantas are now going on a nightly basis and the bay offers a much more protected location from ocean swells. This bay is inaccessible from shore and access requires a boat ride of about 25-30 minutes from the harbor just north of downtown Kailua-Kona.

At first the manta ray encounter began as an event for scuba divers. Over time it became clear that this isn’t just for certified divers! Snorkelers can float at the top and watch the action below. The bright lights that you hold in your hand and shine downward will attract plankton, and the manta rays will swoop up from the deeper water. They often come within inches of you and do a flip as they scoop the plankton out of the water for a tasty snack.

Floating platforms are placed behind the boat and these tiny little “islands” have very bright lights pointing straight down underwater. These bright lights attract the plankton at night, which in turn attracts the manta rays to glide in to scoop up a mouthful of these tiny organisms. When you first enter the water the scene looks like something out of “Close Encounters of the Third Kind” with rays of light beaming down into the water and attracting a host of tiny fish as well as the giant mantas.

The wetsuit that is provided for snorkelers will do two things for you. First, it will help keep you warm since you are snorkeling after dark. Second, it will help you float. Even if you aren’t a good swimmer, you won’t have any problems floating around at the top while wearing a wetsuit. The floating platforms also add a measure of safety as they give participants a place to hold on so they can stay directly above the manta action.

Manta Magic – Hawaii Oceanic

Manta Rays are gentle giants with no teeth, barbs, or stingers. They put on a graceful ballet almost every night as they filter feed on plankton that naturally gathers at the surface just before sunset. This tour departs the harbor just in time to arrive at the manta site for the sunset. The capacity is 6 on one vessel and 10 on their other vessel.  After dark, the plankton concentrate where lights are shining in the water and the mantas will swoop right next to you as they scoop up the nutrients from the water. The Kona Coast is the PREMIER destination in the world for this manta experience.

Manta Snorkel – 40 Foot Speedboat

This Manta Ray Night Snorkel tour is done on a 40′ Coast Guard certified vessel that is fast and comfortable and is well-laid out. Manta rays are often called “the butterflies of the sea” … they are shy, harmless, and graceful. They don’t have any stinging spines on their tail. They don’t bite or chew. Their mouths are designed like a giant funnel to filter plankton. Swimming with them is completely safe for both humans and for the manta rays. They truly are gentle giants – most of the mantas found along the Kona coast have a “wingspan” of 8-13 feet!

Activity Tips

Kevin Ditamore – Owner / Manager

When my wife and I did this adventure for the first time we instantly added manta rays to the top of our “don’t miss it” list. We are excited to offer this opportunity to our clients … this is one of the most unique adventures in Hawaii.

Witnessing manta rays in the wild is a rare treat that can only be done in a few places in the world. The success rate for sighting mantas is incredibly high; somewhere in the 90-95% range. The night that my wife and I did this tour there were 14 mantas, but it seemed like there were far more than that. They kept dancing and gliding from every direction for the entire hour that we were in the water.

While the success rates on the snorkel tour are very high, there is no way to guarantee sightings every single night. The tour operators can’t offer refunds when the mantas don’t show up; their costs for operating the tour are fixed. My advice though is to not let this discourage you; the opportunity to swim with mantas and the high success rate makes it completely worthwhile. If you sign up for this tour you have an extremely high probability of swimming with mantas. If you don’t sign up for this tour you have no chance of swimming with mantas. Sign up for the tour, then be nice to everyone and build up some positive karma in the weeks leading up to the event!

Please note that touching the mantas is not allowed. They have a protective slime coat that keeps them safe from infection and disease, and for the health of the mantas they should not be touched at all. Resist the temptation, even though they are only inches away. Divers stay on the bottom; snorkelers float at the top. All the space in between is allotted for the mantas to conduct their graceful maneuvers.

There is another excellent boat Hawaii Oceanic with only 6 passengers on board for $100 per person. It is listed under private charters, but you can reserve individually. We highly recommend for guests who are looking for uncrowded and guaranteed personal attention from their friendly crew.

Other snorkel options include Fairwind, Hula Kai, Waikoloa Snorkel Sail, Captain Zodiac Rafting, Dolphin Snorkel Swim, and Private Snorkel Charters.
