Kona Manta Ray Night Snorkel Adventure: A Close Encounter with the Giants of the Deep
Planning a trip to the Big Island of Hawaii and looking for an unforgettable experience that combines adventure, stunning marine life, and a touch of magic? The Kona Manta Ray Night Snorkel Adventure offers just that. For $99 per person, you get to float in the dark waters of Kona, searching for the gentle giants that glide gracefully beneath the surface. This tour, lasting around 1 to 2 hours, is led by knowledgeable guides who focus on safety and making sure every guest has a memorable time.
What really sets this experience apart is the small group size—just 13 guests at most—which means more personalized attention and a less crowded, more intimate encounter with nature. We love the thrill of the speedboat ride, which zips out along the Kona coast, and the awe-inspiring sight of manta rays swooping inches from your face under the glow of underwater lights.
One potential consideration is that this activity requires good swimming skills and the ability to climb a boat ladder comfortably. If you’re prone to motion sickness or prefer calmer waters, it’s worth noting the ride can be bumpy and splashy. But if you’re ready for some dark, chilly water and a good dose of adventure, this tour is perfect for travelers craving authentic marine encounters. It appeals especially to those who enjoy guided tours, marine life, and sharing an adrenaline rush with a small, friendly group.

A Nighttime Safari with a Difference
This tour starts in Keauhou, a popular spot on the Big Island, where you’ll be asked to arrive on time to allow for check-in and gear fitting. With about 40 minutes allocated for preparation, you’ll get to meet your guides, gear up, and get a briefing about safety and expectations. Once suited up with masks, snorkels, and wetsuits, you’ll board a speedy Navy Seal Zodiac, which is part of what makes this tour so exciting. The roaring engine, splashes, and fast ride along the coast are half the fun—many reviews mention the boat ride as exhilarating.
In just 4 minutes, you’ll reach the designated snorkel site, a calm bay where the underwater magic begins. Here, guides set up underwater lights and floating boards, which are cleverly designed to attract plankton, drawing the manta rays in for a feeding frenzy. You’ll float on your stomach, holding onto the custom light board, and watch as these majestic creatures glide just inches from your face.
What You Can Expect During the Snorkeling
The snorkeling session lasts around 20 to 30 minutes, giving you enough time to watch multiple mantas swooping and rolling through the water. Several reviewers note the incredible proximity—“Rays were only inches from us,” says one guest—making it a truly up-close encounter. The experience is gentle, with the manta rays doing their graceful loops and flips, often within arm’s reach.
Guides stay on-site, fully equipped with underwater lights and knowledgeable about marine behavior. They’re also CPR certified, which adds a layer of security. One reviewer appreciated that the crew was “friendly, fun, and very attentive,” which helps nervous swimmers feel more comfortable.
The Boat Ride and Its Role in the Experience
Many visitors comment on the speedboat ride—fast, splashy, and a bit bumpy—adding a thrill to the adventure. The journey out and back can take about 30 minutes each way, with the ride back often described as “dark, cold, and splashy” but also fun and invigorating. A few guests mention that the ride might not be suitable for those with mobility issues or those easily seasick, so prepare accordingly.

The Importance of Small Groups and Personal Attention
With just 13 guests, guides can give more tailored assistance, which many reviewers mention as a highlight. Whether helping nervous snorkelers or sharing interesting facts about manta rays, the guides clearly prioritize safety and fun. “The guides were great,” says Daniel, and others commend the crew for making the experience “safe and memorable.”
Flexibility and Practical Details
Guests should be aware that prescription masks are not available, so if you need corrective lenses, consider bringing your own. Also, physical fitness is important—guests should be comfortable swimming and climbing a boat ladder. The tour is suitable for most travelers who meet these criteria, and the age limit generally fits most ages, as long as they can swim and stay afloat independently.
Reviews and Authentic Feedback
The tour consistently receives high praise, with an average rating of 4.7 out of 5 from 130 reviews. Guests love the close encounters with manta rays, often describing the experience as “mesmerizing” and “a must-do in Kona.” Many reviewers highlight the friendly and fun guides, as well as the beauty of the bay and marine life.
However, the experience isn’t without minor drawbacks. A few mention the bumpy ride or slight miscommunications about meeting points, but these issues seem to be minor hiccups rather than deal-breakers. The unpredictability of wildlife means manta rays can’t always be guaranteed, but most guests leave with incredible sightings.
Value for Money
At $99 per person, this tour offers a lot in terms of excitement, intimacy, and access to Hawaii’s iconic marine creatures. Guests often remark that the experience feels worth every penny—especially considering the rarity of swimming with manta rays, which are wild animals and not always present. Tips for enhancing the value include arriving prepared with your own gear if needed, and being flexible with timing and expectations.
Who Will Enjoy This Tour?
This adventure suits travelers looking for a small-group, high-energy experience with a focus on wildlife viewing. It’s ideal for those who enjoy adventure, boat rides, and marine life, and are comfortable in the water. It’s particularly popular among couples, families, and solo travelers eager to see manta rays in their natural habitat without feeling crowded or rushed.
It’s also perfect if you want a nighttime activity that combines thrills with the tranquility of floating beneath the stars, surrounded by the gentle movements of these majestic rays. If you’re seeking a lively, authentic, and memorable Hawaiian experience, this tour hits the mark.
