Experience the magic of Hawaii's night waters with a small-group snorkel tour to see graceful manta rays feeding under underwater lights.

If you’re looking for an unforgettable adventure in Hawaii, a Kailua-Kona Manta Ray Night Snorkel tour promises just that. While we haven’t personally slipped into the water with these gentle giants, this guided experience has all the hallmarks of a must-do for anyone eager for a unique, close-up encounter with nature’s marvels.
What we love about this tour is how it combines a scenic boat ride into the evening, ending with the awe-inspiring sight of manta rays feeding just beneath the surface. Plus, the small-group setting ensures you won’t be lost in a crowd — more intimate, more memorable. On the flip side, it’s a night activity, so if you’re not comfortable swimming in darkness or have certain health restrictions, it might not be ideal.
This experience suits travelers who crave authentic wildlife encounters, enjoy gentle ocean adventures, and appreciate the value of learning about the creatures they’re watching. If you’re after a memorable story to tell or a peaceful yet thrilling way to spend an evening, this tour could be perfect.

Evening activities in Kailua Kona include these interesting options

This tour takes you out from Honokohau Harbor, a scenic start point with easy access and ample parking. The main draw is the chance to see manta rays feed on plankton attracted by underwater lights, in their natural habitat, after sunset. The tour lasts about 2 hours, making it a manageable evening activity that offers both scenic views and wildlife encounters.
Led by Captain Kris Henry, you’ll board a comfortable boat that takes you into the waters off Kailua-Kona, where the magic happens. As the sun dips below the horizon, the boat’s underwater lights turn on, drawing plankton, and with them, the imposing yet gentle manta rays.
The snorkeling portion lasts between 30 to 45 minutes, giving you enough time to marvel at these creatures that can reach wingspans over 20 feet and weigh over a thousand pounds. The experience is designed to be up-close and personal, allowing you to see their graceful movements and enormous wingspans up front.

The tour begins at Honokohau Harbor, a well-organized spot with clear directions: after turning down the harbor road, take a right past “The Yard” sign, and you’ll find a large gravel parking lot with free parking. Look for the brown-roofed pavilion, which is the central meeting point and has bathrooms — a small but important detail after a day of travel.
Be sure to check in 15 minutes early to handle any paperwork and safety instructions. The experience is live-guided in English, and the small group size usually feels more like a friendly gathering than a big tour bus.

As darkness settles, underwater lights are turned on to attract plankton, which in turn draws the manta rays from miles around. The sight of these majestic creatures gliding gracefully, wings spread wide, is described as “breathtaking” by many. Their gentle, almost hypnotic movements are a highlight, and the fact that they feed at night adds a sense of intimacy and magic not found in daytime viewing.
Once in the water, you’ll float alongside them, marveling at their quiet, deliberate movements. Many reviewers comment on how peaceful and almost surreal it feels to watch these giants so close. The guide will provide insights into their behavior and biology, enriching the experience beyond just watching.
The 30-45 minutes in the water gives plenty of time to get used to the darkness, enjoy multiple sightings, and perhaps even snap a few photos if you’re quick with your waterproof camera. Keep in mind that diving gear is provided, but it’s your comfort and confidence in the water that will determine how much you enjoy this.
After the snorkeling, the boat gently returns to the harbor. Many guests reflect on how this peaceful, awe-inspiring encounter is one of the most memorable moments of their trip. The overall atmosphere is one of wonder, with many describing the experience as “otherworldly”.

This experience is ideal for adventurous travelers, wildlife enthusiasts, couples, and families with older children who are comfortable in the water. It’s especially suitable for those seeking a peaceful, authentic moment with nature rather than a high-energy activity.
