Kona Manta Rays Guaranteed Night Snorkel in Keauhou Harbor

If you’re looking for an unforgettable evening activity on Hawaii’s Big Island, the Kona Manta Rays Night Snorkel is a popular choice — and for good reason. This tour promises a chance to see the majestic manta rays feeding in their natural habitat after sunset, an experience that most travelers find both surreal and humbling. What we love about this tour is its intimate setting, thanks to small-group size, and the expert guides who focus on safety and respect for these gentle creatures. We also appreciate the unique lighting setup that attracts the rays without disturbing them, adding to the magic of the experience.

However, it’s worth noting that the tour is weather-dependent, and you’ll need to be comfortable in the dark in open water. If you’re prone to seasickness, floating on a light board for about 30 minutes might be a challenge. Still, for those who love marine life and are seeking an authentic, up-close encounter, this tour often hits the mark. It’s particularly well-suited for confident snorkelers looking for a memorable night adventure with a good chance of spotting multiple manta rays.

An Overview of the Experience

This tour begins at a meeting point in Kailua-Kona, a convenient spot easily reachable for travelers staying on the Big Island. Once aboard a small boat—capped at 17 guests—you’ll quickly head out to Keauhou Harbor, just a few minutes offshore. The short boat ride in the evening darkness sets the tone, with the crew providing a friendly introduction and safety instructions.

The main highlight is the custom-made light board that emits 150,000 lumens, designed specifically to attract plankton—the manta rays’ favorite snack—without harming the creatures or disturbing the environment. You’ll float on the warm waters, with most guests using a provided snorkel, mask, and lifejacket (which are included), to keep it simple and accessible. Wetsuits and additional lifejackets are optional but not required, making this a flexible outing.

How the Snorkel Unfolds

Once in the water, the guides focus on keeping everyone safe and comfortable, especially those who may not be seasoned swimmers. Several reviews mention how helpful and knowledgeable the guides are, with Beth_B praising the crew for being “very knowledgeable about the Manta Rays and super helpful.” The small group size means closer, more personal viewing, avoiding the crowded boat vibe that can sometimes diminish the intimacy of such encounters.

As the rays approach, you’ll see them glide effortlessly, feeding on the plankton attracted by the light. Many reviewers describe their sightings as “absolutely incredible,” with multiple rays circling close enough to touch. Stephanie_Z notes that “you don’t even think about the looming darkness of the depths when you see these beautiful angels emerge.” The rays are generally gentle, and the guides emphasize respect and non-intrusiveness.

The Guarantee and the Value

One of the most attractive aspects of this tour is the guarantee policy. If you don’t see manta rays, you can come back for free. Several reviewers, including Sheila_S, mention how they appreciated the confidence this gives, and that it makes the price of $89 more palatable — knowing you have a backup plan if the creatures are shy that night.

The overall value is strong, especially considering the included gear, the small-group experience, and the professionalism of the crew. Plus, many travelers find that the experience is worth every penny, “a once-in-a-lifetime moment,” as Christine_C put it, especially when multiple rays come close enough to make you think they might just brush past you.

The Itinerary in Detail

The tour is straightforward but thoughtfully designed. It begins with check-in at the designated meeting spot, where friendly staff will brief you on safety and what to expect. After donning your gear, you’ll hop onto a small boat that swiftly takes you into the dark waters of Keauhou Harbor.

The boat ride lasts about 3 minutes, a quick and scenic transition from land to sea, giving you a taste of the island’s evening atmosphere. Once in position, guides will give verbal instructions and safety briefings—important, since snorkeling in dark, open water requires some confidence and familiarity with your gear.

The main activity involves floating on a specially lit board, which helps attract plankton, and in turn, the manta rays. This floating position is surprisingly comfortable, even for those who might worry about seasickness, as long as you’re prepared for gentle waves and know how to keep your balance. The guides remain attentive throughout, monitoring the group and providing support when needed.

In the end, the tour wraps up after about 1 hour 20 minutes, with guests returning to the harbor by boat, often buzzing with the thrill of having seen multiple manta rays.

What Makes This Tour Special

Small group size is one of the biggest pluses. With a maximum of 17 guests, you won’t feel lost in a crowd, and you’ll have better opportunities to get close to the rays without disturbing them. Reviews like Liz_K’s highlight the professionalism and friendliness of the crew, which makes all the difference in such a delicate environment.

Guides are certified in-water professionals who focus on safety and education. Many reviewers appreciate their knowledge and enthusiasm. Beth_B mentions the crew as “very knowledgeable” and helpful, which reassures travelers who might be apprehensive about swimming at night.

Lighting technology is key to this experience. The custom-made light board is both powerful and eco-conscious, designed specifically to attract manta rays with minimal environmental impact. Several reviews note the rays’ close proximity, with some describing sightings of 8 to 13 rays circling around — a truly mesmerizing sight.

The guarantee policy offers peace of mind, especially for first-time snorkelers or nervous swimmers. If no rays are spotted, you can rejoin for free. This policy demonstrates confidence in the tour’s success and adds value to the cost.
