If you’re researching things to do in Kona, Hawaii, snorkeling with manta rays is one experience that belongs at the top of your list. The Travel Channel named it one of the “Top 10 Things to Do in Your Lifetime” — and after doing it myself, I understand why. Here’s everything you need to know to plan your own manta ray night snorkel in Kona.
What Is the Kona Manta Ray Night Snorkel?
Kona is one of just a few places in the world where you can snorkel with manta rays, which is a big reason this has become such a popular activity for visitors.
Even though there are dozens of tour operators in Kona offering night snorkel manta ray tours, the experience itself follows a fairly standard setup. Participants board a boat and travel to Makako Bay, also known as “Manta Ray Heaven,” located about 100 yards offshore near the Outrigger Resort in Kona.

Once you reach the site, each participant enters the water and swims a short distance to the viewing platform.
Manta rays are filter feeders that survive almost entirely on plankton. Tour operators use specialized underwater lights attached to floating viewing platforms to attract plankton to the surface — and the manta rays follow. The result is an up-close, face-in-the-water encounter with some of the ocean’s most majestic creatures.
Most tours run about 2 hours total, with roughly 30 minutes actually spent in the water with the manta rays.
Are Manta Rays Dangerous?
This is the first thing most people ask — and the answer is no. Manta rays are completely harmless to humans. They have no teeth and no stingers. (And no, they’re not the same animal that killed Steve Irwin, those were stingrays.) In fact, they’re considered some of the most intelligent creatures in the ocean, which makes them curious and surprisingly interactive with snorkelers.
That said, manta rays are a protected species, and touching them is illegal. Your tour guide will brief you on proper behavior before you enter the water.
What to Expect on the Tour
Here’s a realistic breakdown of what the experience looks like from start to finish:
On the boat: Most tours last about two hours total. The majority of that time goes toward safety briefings, getting into wetsuits, and the boat ride out to the snorkel site.
In the water: You’ll typically spend around 30 minutes actually snorkeling. Guides direct you to floating viewing platforms — essentially surfboards fitted with PVC pipe railings and bright lights on the underside. You hold the railing, tuck a pool noodle under your ankles to float flat with your face in the water to watch the manta rays.
The manta rays: When they show up, they move in wide circular loops — rising toward the lights with their white bellies facing up, then descending and looping back around. Their wingspan can easily exceed the width of the viewing platform, and their wingtips may come within inches of snorkelers on either side. The scale of it is genuinely surprising.
I wasn’t expecting them to be quite so large — or quite so close. The moment I put my face in the water and came eye-to-eye with a giant manta ray, I completely forgot I was floating in a pitch-black ocean at night.
How Much Does It Cost?
Expect to pay $100–$200 per person depending on the operator and level of service. Higher-end tours offer smaller groups, better gear, and more attentive guides. Budget options are more bare-bones but can still deliver the same manta ray encounter.
Tips for Booking
Book early in your trip. Tours occasionally strike out — manta rays are wild animals, and there’s no guarantee they’ll show. If you book toward the beginning of your vacation, you’ll have time to go again if needed.
Look for a guaranteed return policy. Many operators offer a free repeat tour if no manta rays are spotted. This is well worth prioritizing when comparing companies.
Consider a sunset tour. If you’re not thrilled about jumping into pitch-black water (I wasn’t), some operators offer sunset departures. You head out before dark, and there’s still a glow on the horizon when you enter the water. The sunset views from the boat are spectacular and take the edge off the nighttime element.
Book ahead. These tours sell out, especially during peak season.
Best Time of Year to Go
Manta rays can be seen year-round in Kona. However, January through March tend to bring fewer rays and rougher seas due to Hawaii’s winter weather. If flexibility allows, aim for late spring through fall for the most favorable conditions.
What to Know Before You Go
- Swimming ability: You need to be a confident swimmer. Getting to and from the viewing platforms requires swimming through open ocean water.
- Seasickness: Even on a short boat ride, the boat sits parallel to rolling swells while you’re in the water — and the smell of diesel from surrounding vessels doesn’t help. If you’re even slightly prone to motion sickness, take Dramamine beforehand. Floating flat on the surface can intensify the feeling.
- Wetsuits: Provided by your tour operator. The water is warm, but a wetsuit is still standard for comfort and buoyancy.
- No touching: Manta rays are federally protected. Keep your hands on the platform railing at all times.
Is It Worth It?
Yes — without hesitation. Snorkeling with manta rays in Kona was one of the most memorable experiences I’ve ever had. There’s something about being inches away from a creature that enormous, moving that gracefully, in the middle of the ocean at night, that puts life in perspective in a way that’s hard to explain until you’ve felt it.
