Manta Ray Night Snorkel Adventure in Kailua-Kona: A Deep Dive into the Big Island’s Underwater Magic

If you’re dreaming of swimming alongside majestic manta rays beneath a starry Hawaiian sky, the Manta Ray Night Snorkel in Kailua-Kona might be just the ticket. For around $137 per person, this two-hour small-group tour takes you to the renowned ‘Manta Heaven’—a spot famous for its nightly manta feeding displays. Led by certified guides, equipped with snorkeling gear and wetsuits, and with a maximum of 18 guests, this adventure promises an intimate encounter with one of Hawaii’s most captivating marine creatures.
What we love about this tour is the chance to witness the graceful movements of manta rays, often up close, in their natural feeding environment—something truly unforgettable. The short boat ride from Honokohau Harbor to the site is scenic, offering views of stars, city lights, and the vast Pacific. Plus, the inclusive gear and expert guidance make this accessible even for those with basic snorkeling skills.
However, a word of caution: manta sightings aren’t guaranteed since these creatures are wild animals with free will to appear or not. Also, check-in times can be up to 40 minutes before the tour, so punctuality is key. This experience is best suited for travelers who enjoy adventure, marine life, and are comfortable in the water—and those who appreciate well-organized, small-group excursions.

Exploring the Manta Night Snorkel in Kailua-Kona

The Kailua-Kona manta night snorkel combines adventure, education, and awe-inspiring sights, making it a highlight for many visitors to the Big Island. Here’s a detailed look at what you can expect and how to make the most of it.
The Location: From Honokohau Harbor to Manta Heaven
Your journey begins at Snorkel Big Island’s meeting point in Kailua-Kona, where you’ll check in and gear up. The 15-20 minute boat ride is part of the experience—you’ll be hanging onto a custom-made light board that attracts plankton, which in turn draws the manta rays. During the boat ride, you can look up at the stars, take in the gentle sway of the ocean, and enjoy the anticipation of what’s to come.
What Makes the Location Special?
Garden Eel Cove, known as ‘Manta Heaven,’ is a favorite spot because of its dependable nightly manta activity. The site’s calm waters and the deep understanding of local guides contribute to a safer, more enjoyable experience. The southern site, Manta Village at Keauhou, offers similar opportunities, but guides typically choose based on conditions.
The Snorkeling Experience: Floating Among Giants
Once in the water, you’ll float lightly tethered to a custom-made light board—a simple yet ingenious way to attract plankton and, ultimately, mantas. The guides help position everyone for optimal viewing, aiming to give you the best chance of seeing these gentle, acrobatic creatures up close.
You’ll love the way the manta rays seem to glide effortlessly beneath you, their large silhouettes illuminated by the light. The experience is often described as surreal—a chance to observe these wild animals in their natural feeding behavior, with some guests quoting the activity as “magnificent” and “really, really great.”

Guides and Safety
The tour is led by certified guides and lifeguards, ensuring your safety while providing fascinating insights. According to reviews, guides like John and Elijah are highly praised for their professionalism and friendliness—crucial when you’re floating in open water at night.
Good communication and safety briefings are standard, and if you or someone in your group prefers a lifejacket, the guides are happy to provide one. Basic swimming skills are a must, and guests should be able to climb a boat ladder independently.
The Duration and What’s Not Included
The tour lasts approximately two hours, with the boat ride, snorkeling, and debriefing included. All gear—snorkel masks, fins, wetsuits—is provided, removing the guesswork and expense of bringing your own equipment. However, private transportation to the site and prescription masks are not included, so plan accordingly.
The Authenticity and Value of the Experience

Many visitors find this tour offers a remarkable value for the price. For about $137, you get professional guidance, all gear, and a chance to witness one of Hawaii’s most iconic marine spectacles.
Yet, it’s important to recognize that wild animals can be unpredictable. One review amusingly notes, “Manta Rays are wild animals and Snorkel Big Island cannot guarantee their presence.” If you do not see mantas on your night out, you’re invited to try again on another evening—sometimes, persistence pays.
The Small Group Advantage
With a maximum of 18 guests, the tour fosters a more intimate environment compared to larger boat trips. This means more space, less noise, and the opportunity for personalized attention from guides, which enhances the overall experience.
What to Keep in Mind
Before booking, check-in times should be confirmed directly with the operator—up to 40 minutes prior to departure. It’s also essential to arrive on time and be prepared for potentially cool water temperatures, which wetsuits help mitigate. Since weather can impact the tour, be flexible with dates if conditions aren’t ideal.
Authentic Reviews: Real Experiences from Real Travelers

One traveler recounts a disappointing experience where they arrived on time but no one else was there, and attempts to reach the company failed. The review states, “Very sad experience,” but the company responded apologetically, issuing a refund. This underscores the importance of confirming reservations and arriving promptly.
On the positive side, another guest describes the trip as “outstanding,” emphasizing the friendly crew and trustworthy guides like John and Elijah, making the experience especially memorable for their family. The contrast highlights how reliable guides and preparation can make or break the adventure.
Who Should Consider This Tour?

This snorkel is perfect for adventurous travelers who enjoy marine wildlife and are comfortable in open water at night. It’s suitable for families with children who meet basic swimming abilities, and those who appreciate small-group, personalized tours. If you’re seeking a unique, close-up encounter with manta rays in their natural habitat, this experience delivers.
However, if you have physical or mobility restrictions, check the specifics, as the tour isn’t recommended for travelers with mobility issues. Also, those who prefer guaranteed sightings might want to consider the policy that mantas are wild animals and sightings cannot be guaranteed.
The Sum Up: Is the Manta Night Snorkel Worth It?

In essence, this tour offers a rare chance to see majestic manta rays in their natural environment, illuminated by the glow of underwater lights. It’s a value-packed experience that combines scenic boat rides, expert guidance, and close-up wildlife viewing—all within a manageable two hours.
If you’re a marine enthusiast or simply looking for a memorable night activity in Kailua-Kona, this adventure is worth considering. The small-group setting, knowledgeable guides, and stunning vistas make it a genuine highlight of many travelers’ trips.
On the flip side, keep in mind that wildlife sightings are unpredictable, and your experience depends heavily on the animals’ willingness to appear. Arrive early, be prepared, and manage expectations, and you’ll likely go home with some incredible stories—and maybe even some manta ray photos.
Overall, for moderate cost and maximum authenticity, this tour is best suited for those who value quality guides and natural encounters over guaranteed sightings. It’s an experience that, with a bit of luck, can become one of the most unforgettable moments of your Hawaiian vacation.
