Swimming and snorkelling with manta rays is not an everyday event for you; you want an amazing underwater adventure you can thoroughly enjoy.
However, with 50+ operators offering the manta ray activity on the Big Island of Hawaii, chances are you’ll get packed with a boatload of tourists. You don’t want to end up in the water with dozens of other snorkellers and divers, lost in the chaos – and disturbing the manta rays on top of that.
At Manta Ray Advocates, the mantas always come first. We adhere to strict guidelines to make sure the manta rays don’t get disturbed by our presence. We approach the mantas from the beach, an eco-friendly alternative to sightseeing boats.
The manta ray night snorkel in Kona should be completely safe, for the mantas as well as for you. With 50+ years of combined field experience, we know how important it is to brief you on safety before we start – and we only work with top-notch equipment.
Instead of traveling on a boat to one of the busy viewing areas, we enter the ocean from a georgous white sandy beach and swim to where the manta rays are feeding. Read more about the location here! We work with small groups (up to 6 people), so we can give every guest the personal attention they deserve and make the experience highly educational for everyone.
One of the most amazing experiences a human can have. And one flicked its wing and hit me on the hand – it was unexpected and so exciting. Made me feel blessed to be so fortunate. A wonderful antidote to negativity bias!
This is the time of the day when manta rays come to feed. Lights at the viewpoint attract zooplankton, and the manta rays associate those lights with food. Read more about this here.
Our reservation system was updated recently and gave us the option to only require a deposit during the sign-up process.
We feel this is a great chance to not hold your funds for too long on our end, so we now require a 40% down payment.
On the night of the activity, we expect payment of the balance at the beach shack with a credit card, cash, or Apple Pay. Room charges are not possible.
Please give us a call if you prefer to pay us in full: 808-987-5580 (9 AM to 3 PM HST)
We’ve been using our location at the Mauna Kea Beach Hotel for several years now – we love that we get to use a private beach for a unique and relaxing experience. No boat involved. Read more about the location here.
There are 3 reasons why you need a guide:
No, the water temperature does not change between day and night. It is generally around 78-82 degrees Fahrenheit (21-25 degrees Celsius).
The minimum age for children is 12 years old. All 12- and 13 years old children must be accompanied by a parent or legal guardian. Learn more here about why we decided to raise the age from 10 to 12.
Maximum: What’s important is that you’re a good swimmer and physically healthy enough to walk along the sandy beach to last 30-40 minutes snorkeling in the ocean. Read about Martina’s mom and her adventure of swimming with the manta rays at age 82!
We have designed the tour to be relaxing and not too taxing. We do require you to be able to swim in water too deep to stand and have basic ocean snorkel experience. We encourage you to refresh your snorkel skills in the hotel pool and ocean and establish a comfort level with the equipment in the brightness of the day.
Our moonlight swims are open to anyone over 12 years old. We even get guests that are over 80 years old…
No, manta rays are notorious pacifists. In case you’re wondering – Steve Irwin was killed by a stingray, a much different creature. In 30 years of scuba diving along the Kona coast, we have only seen stingrays twice – and never at our location. Stingrays stay in much deeper water, and are very shy creatures.
No, we have never seen sharks during the activity.
No, touching removes a protective coating from their skin and this is harmful to the manta rays. Trying to ride or touch them can harm or kill them. More about this here.
Snorkeling only. If you’d rather scuba dive: see Hawaii Ocean Watch Greenlist.
Take it easy on the day of the activity by relaxing on the beach. Practice snorkeling in the hotel pool and ocean so you’re confident the gear is comfortable and fits right. Eat something so you are not hungry during the activity. Have a Plan B just in case we have to cancel due to ocean conditions.
Sometimes, ocean conditions force us to cancel our moonlight swim, especially during the winter months from mid-December to end of March. We keep you updated by text and email so you’ll know as soon as we know.
Does it get rescheduled? – YES, if possible, we do our best to make things happen for guests.
We meet at the beach activities kiosk of the Mauna Kea Beach Hotel.
Please bring a swimsuit, swim shirt and you are welcome to use your own snorkeling gear.
—> Full-face masks are not permitted, only the classic style mask with a separate snorkel.
We supply high-quality masks, fins, snorkels, safety flotation vests, and towels.
There is a freshwater shower for your convenience, afterward, as well as restrooms and changing rooms.

Underwater cameraman at heart, James founded “Dolphin Dreams Imaging” (and today’s Manta Ray Advocates) in 1991. He was the first photographer for the manta ray dive at Manta Village (Keauhou) and established Manta Heaven (airport) in 1999.
When he retired from diving and filming in 2014, he pivoted from production and set up the manta ray moonlight swim program with the Mauna Kea Beach Hotel.
He’s a PADI master diving instructor, ocean educator, and loves sharing his in-depth knowledge about manta rays. His field-experience with the gentle giants along the Kona Coast is unmatched.
Martina is a passionate manta ray advocate, ocean educator, and underwater camerawoman. She lives in Kailua-Kona, Hawaii, with hubby James.
Martina’s all about raising awareness and spreading knowledge about the gentle giants of the sea, so we can better protect them from harm – and people will be able to experience manta rays (online and in real life) for generations to come.
Her love for the mysterious manta rays inspired her to teach other people about marine life and the uncountable wonders taking place in our oceans. Martina has been filming manta rays (and other underwater stories), as well as guiding people who come to swim with the gentle giants in Hawaii for over 20 years.
Kerstin got her diving certification in the Maldives in 1998. After finishing her divemaster in Thailand (2010), she followed through with the PADI Instructor (2011) and has worked around the beautiful reefs of the Red Sea (Egypt), Bali, Thailand, and the Florida Keys. In 2017 she moved to the Big Island of Hawaii.
Kerstin cherishes small critters and large marine life alike and loves introducing people to them. She’s passionate about making the mantas’ home safer and working towards a sustainable future for the ocean, that everyone can benefit from.
