Kona Town Manta Sunset Snorkel: A Unique Nighttime Encounter with Hawaii’s Gentle Giants

When thinking of the Big Island of Hawaii, most travelers picture volcanoes, lush rainforests, and beautiful beaches. But for a truly unforgettable experience, you might want to add night snorkeling with manta rays to your list. For $150 per person, you’ll spend about 90 minutes exploring the waters off Kona with a small group, guided by knowledgeable locals—an experience that’s often considered a highlight of any trip to Hawaii.
What we love about this tour is how close you get to these majestic creatures—graceful manta rays that glide effortlessly beneath you, illuminated by special lights that attract plankton and zooplankton. The other big plus is the expert guides, who not only ensure your safety but also enrich the experience with their insights about manta behavior and the local marine environment. Plus, the evening snacks and use of quality snorkeling equipment make the outing feel well-rounded and comfortable.
A potential consideration is the weather—since this is a night snorkel, poor weather or rough seas could lead to cancellations, which might disappoint those who are eager for this experience. Also, since the tour caps at 10 travelers, it’s intimate, but that means booking early is wise to secure your spot.
This tour is ideal for travelers who enjoy water-based activities, are comfortable snorkeling in the dark, and want an authentic encounter with Hawaiian marine life. It’s especially suited for those seeking a peaceful, awe-inspiring adventure without the crowds.

Exploring the Kona Town Manta Sunset Snorkel in Detail

Starting Point and Timing
The adventure begins at 75-5660 Kopiko Street, Kailua-Kona, with the tour starting promptly at 6:00 pm. This timing makes sense because manta rays are most active at night, and the darkness enhances the visual spectacle of the illuminated plankton attracting the mantas. The meeting point’s proximity to public transportation can be a plus if you’re staying nearby, though most visitors will likely need to arrange a short drive or taxi.
The Experience Itself
Once everyone gathers, the guides—most notably friendly and bilingual—brief you on safety and what to expect. We loved the way they emphasize respecting the marine environment and maintaining a safe distance from the mantas. The use of bright lights is central to the experience, as it attracts the plankton, which in turn draws the mantas. As the mantas approach, you’ll see these graceful creatures perform their barrel rolls and feeding loops, a mesmerizing sight that’s difficult to describe in words.
The water will be cool, but the provided snorkeling gear is comfortable and effective. Expect to float peacefully, watching as the mantas glide effortlessly in and out of your light’s glow. Many reviews highlight how majestic and gentle these animals are, making the encounter feel almost surreal. One reviewer remarked, “We loved the way the mantas moved so smoothly, as if they were part of the night itself.”
What’s Included and What to Bring
Aside from the snorkeling gear—which is well-maintained and suitable for both beginners and experienced snorkelers—the tour includes snacks. You might find that the snacks are simple, but they’re appreciated after the swim, especially since you’ll be in the water for about an hour. The tour also offers an English and Japanese-speaking guide, making it accessible for a broader range of visitors.

The Group and Atmosphere
Limited to 10 travelers, the small size ensures a relaxed and less crowded experience. This also means you get more personalized attention and chances to ask questions during the tour. Several reviews note how the guides foster a friendly, informative environment—helping first-timers feel comfortable and confident.
Cancellations and Weather Considerations
Since the tour relies heavily on good weather, poor weather conditions could lead to cancellations. The policy states that if canceled due to weather, you’ll either be rescheduled or offered a full refund. This is a sensible approach because snorkeling in rough seas or stormy weather would diminish both safety and enjoyment.
Why This Tour Offers Great Value

Compared to other Hawaii activities, night snorkeling with mantas offers a rare chance to see these fascinating animals in their element, free from the crowds and bright daytime tourism. The price of $150 includes quality gear, guides, snacks, and the experience of a lifetime.

Authenticity and Safety

Accessibility and Suitability
While some physical activity is involved—swimming in the dark with equipment—the tour is suitable for those with moderate fitness levels. It’s not overly strenuous, but you should be comfortable in open water and able to swim or float independently.

If you’re intrigued by marine life, enjoy gentle adventure, and don’t mind a late evening, you’ll find this night snorkel unforgettable.

If you’re traveling with family, make sure everyone is comfortable with night swimming. It’s also great for couples or solo travelers eager for a peaceful, mesmerizing activity that’s quite different from daytime snorkeling.
Final Thoughts: Who Will Get the Most Out of It?
For anyone looking to see Hawaii’s marine creatures in their natural habitat, this tour offers an intimate, safe, and genuinely moving experience. It’s perfect for those who value authentic encounters over crowded tourist spots and want to learn about marine behavior from passionate guides.
