Kona Manta Rays Guaranteed Night Snorkel in Keauhou Harbor

If you’re heading to the Big Island of Hawaii and dreaming of watching those gentle giants glide through the water, you’ll want to hear about this night snorkel tour. It’s one of the most talked-about experiences for wildlife lovers and anyone looking for a truly magical moment in the ocean. While I haven’t personally been on this exact tour, I’ve gathered enough genuine insights to give you a clear picture of what to expect.

One thing we love about this tour is the proximity to the manta rays — with a small group size and guided approach, there’s a real chance to see these creatures up close without disturbing them. Plus, the guarantee policy is pretty reassuring: if you don’t see any rays, you can come back for free. That says a lot about the confidence of the operators.

On the flip side, a possible thing to consider is the short duration of the water time, which is around 30 minutes in the water. For some, that might feel a bit quick, especially if you’re eager for more underwater adventure. But overall, this experience is best suited for those who want a focused, intimate encounter with the manta rays in their natural habitat without the crowds.

If you’re comfortable with snorkeling, enjoy small, guided tours, and are looking for an awe-inspiring, affordable activity that combines adventure with education, this tour could be a perfect fit.

What to Expect from the Tour

This night snorkel adventure begins with a straightforward check-in process at the meeting point in Kailua-Kona. You’ll be fitted with a wetsuit and snorkeling gear — these are included, with the wetsuit being optional but recommended if you want to stay warm, especially in cooler waters. The tour’s overall price is $69 per person, which, considering the experience, feels quite reasonable.

Once geared up, you’ll hop onto a small boat for a quick 3-minute ride to your snorkel spot, cutting down on travel time and maximizing your time with the mantas. The short ride is a plus, especially if you’re prone to seasickness, as the boat ride isn’t long or bumpy.

When you arrive at the site, your guides — who are certified in-water — will give you a safety briefing and helpful instructions. The guides are known for their knowledge and friendly approach, helping even nervous snorkelers feel comfortable. The entire experience is designed to be safe, non-intrusive, and intimate, so you can really enjoy the moment.

The highlight is floating on a custom-made light board that attracts plankton, which in turn attracts the manta rays. As you float, your guide will be close by, providing commentary and ensuring your safety. Expect to spend about 30 minutes in the water, floating alongside the rays which can come surprisingly close — sometimes within inches of your face, as multiple reviews point out.

The atmosphere is quite surreal. Many reviewers describe it as “unbelievable,” with a sense of awe and wonder. You’re in warm, calm waters, witnessing a natural feeding ritual of these majestic creatures in their own environment.

The Experience in Detail

The tour’s small boat approach is a real advantage. It allows closer contact with the manta rays without disturbing them — a delicate balance that guides work hard to maintain. While larger boats might chase the experience, this smaller setup feels more respectful and personal.

The light board, which emits 150,000 lumens of light, is the key attraction. It attracts plankton, which in turn draws the manta rays near. Many guests mention how the rays come so close that it almost feels like a rendezvous with underwater angels. As one reviewer put it, “You can see so many manta rays, they come right up to you, and they’re incredibly ethereal in person.”

The guides’ role isn’t just to help you see the rays but to ensure your safety. They are experienced, friendly, and knowledgeable, often giving helpful tips or information about the mantas’ behavior and ecology. This makes the experience not just thrilling but educational.

Duration in the water is just enough — about 30 minutes — which many find perfect. It’s enough time to see multiple rays and enjoy the glow of the underwater light show without feeling overstayed or exhausted.

The return to the shore is quick and smooth. You’ll be back at the starting point, ready to continue your evening or head to your next adventure.

Price and Value

At $69 per person, this tour is a pretty solid deal for such a unique, once-in-a-lifetime chance to see manta rays up close. The included gear — masks, snorkels, and optional wetsuits — adds to the value, especially considering the experience. Plus, with a guarantee policy, if you don’t spot any rays, you can come back again free, which reduces the risk of disappointment.

Guests consistently mention that this experience feels worth every penny, especially when you consider how close and personal the encounter is. Many reviews highlight that the guides make the difference — their enthusiasm, professionalism, and local knowledge elevate the tour from just a swim to a memorable adventure.

Group Size and Atmosphere

The tour caps at 17 guests, which helps keep the environment intimate. It avoids the crowded, noisy boat vibe that can sometimes spoil wildlife tours. The small group size means more individual attention from guides and less disturbance for the manta rays. Several reviews praise the friendly crew and how they make everyone feel comfortable, even if you’re nervous about snorkeling in dark waters.

Practical Tips for Your Night Snorkel

• Book in advance — the tour is popular and often booked 18 days ahead.
• Bring a waterproof case or GoPro if you want to capture the moment, as many reviewers suggest.
• Wetsuits are optional but recommended for staying warm during the 30-minute float.
• Basic swimming skills are necessary, and you should be comfortable in open water.
