Experience the magic of Kona’s night-time manta rays with this intimate, guided snorkel tour featuring stunning sunset views and close encounters beneath the surface.
If you’re dreaming of seeing one of Hawaii’s most mesmerizing marine spectacles, a night snorkel with manta rays in Kona offers a rare chance to witness these gentle giants in their natural environment. This tour, operated by Ocean Eco Tours LLC, is designed to give travelers a personal, relaxed experience with a focus on comfort and authenticity. While it’s not a large-group cruise, it promises a front-row seat to nature’s nightly ballet, making it a memorable highlight of any Big Island itinerary.
What makes this tour particularly appealing? First, the small-group setting ensures you won’t be lost in the crowd—perfect for those who enjoy a more intimate adventure. Second, the combination of a scenic sunset cruise followed by close-up manta encounters captures the best of what Kona’s waters have to offer. On the flip side, a possible limitation is that good weather and marine conditions are essential for optimal manta sightings, and no sightings are guaranteed. Still, with a manta guarantee policy, you can enjoy the peace of mind that your investment is protected.
This tour is ideal for travelers who want a relaxed, beginner-friendly experience—no prior snorkeling expertise needed—yet still crave the thrill of these majestic creatures. It suits families with children over 5 and anyone comfortable floating on the surface. If you’re after a personalized experience and can appreciate a beautiful sunset as part of the package, this trip could be just right.

The trip begins at Honokohau Harbor, where a scenic sunset cruise sets the tone. As the boat gently glides across the waters, guides share interesting facts about manta rays and the local marine environment, adding educational value to the relaxing ride. Travelers often mention how peaceful and beautiful the sunset views are, making this part of the experience enjoyable even before the snorkel begins.
Once the sun dips below the horizon, the boat anchors at the designated snorkeling site—either the northern or southern manta sighting location—whichever offers the best conditions that evening. This flexibility is crucial, as weather and ocean currents can influence manta activity, and the crew is diligent in choosing the most promising spot.
The core of the tour is the night snorkel, which lasts approximately 30 to 40 minutes. You’ll float on the surface, holding onto a custom light board that emits powerful beams attracting plankton. This, in turn, draws the manta rays close enough for an unforgettable view. You’ll see them looping and gliding beneath you, often within arm’s reach—a spectacle that’s truly unlike anything else.

Guides emphasize that you only need to be able to float at the surface and use a mask and snorkel—no free swimming skills are necessary, making this tour accessible to most. For many, the most striking part is the gracefulness of the mantas—they seem to float effortlessly, their large bodies undulating smoothly, often silhouetted against the glowing plankton.
Several reviews highlight how close and personal the encounter feels. One said, “Watching the manta rays loop around us was awe-inspiring—like flying through a dream.” Others appreciate the educational insights provided, which help deepen understanding of these gentle giants and their nightly feeding habits.

All snorkel gear and flotation devices are included, removing the hassle of renting or bringing your own equipment. The small group size—a maximum of 12 guests—means you’ll enjoy plenty of space in the water and personalized attention. This intimacy helps create a more relaxed atmosphere, especially for those new to snorkeling or prone to feeling overwhelmed in larger crowds.
The tour’s duration of about 2 hours strikes a good balance; it’s long enough to soak in the atmosphere and see the mantas, but not so lengthy that it becomes tiring. The boat departs from Honokohau Harbor, giving the crew the flexibility to reach the best site for that evening’s conditions.
Reviews reflect a generally high satisfaction level. Many mention how stunning the views are, especially at sunset, with some noting that seeing mantas up close is an experience like no other. However, a few travelers mention that manta sightings are not guaranteed, which is typical for wildlife tours. The tour’s flexibility and manta guarantee policy are reassuring for those concerned about the unpredictability.

This snorkel adventure is perfect for travelers seeking a personalized, educational experience with minimal crowding. It’s suitable for families with children over 5 who are comfortable floating, as well as for those new to snorkeling. The combination of sunset and night snorkeling makes it especially appealing for visitors who want a scenic, relaxed environment with a touch of adventure.
Unlike larger commercial cruises, this tour emphasizes quality over quantity—fewer guests mean more space and attention. The inclusiveness of gear and the flexible site selection ensure you’re well cared for, whatever the weather or marine conditions. Plus, the manta guarantee policy provides peace of mind, making this experience a worthwhile investment for anyone eager to encounter Kona’s famed manta rays.
In terms of timing, the two-hour window fits well into most travel schedules, offering a manageable evening activity without feeling rushed. The scenic sunset cruise alone is worth the price for anyone who loves watching the big sky turn colors over the ocean, adding a special touch to the whole experience.
This tour strikes a commendable balance: it’s accessible for beginners, offers a personalized and intimate setting, and delivers the stunning views and close encounters that make Kona’s manta nights so special.

Just remember, nature is unpredictable, but with the careful planning and flexible site choices, your chances of a memorable manta sighting are excellent.
