From Keauhou Bay: Manta Ray Night Tour — A Close Encounter with Nature’s Gentle Giants
If you’ve ever dreamed of swimming alongside majestic manta rays in their natural environment, this night tour from Keauhou Bay offers exactly that. For around $130 per person, you’ll spend about one hour on the water, guided by knowledgeable experts who will help you witness these incredible creatures performing their slow, elegant underwater ballet. Led by guides like Sarah and Matt, this tour promises an unforgettable experience that combines adventure, awe, and a touch of the surreal.
What we really love about this experience is how close you get to the mantas — they swim near enough to see their enormous, paddle-like fins and their otherworldly, large mouths that scoop up plankton. Plus, the lights used to attract the mantas give the whole scene a magical glow that transforms the ocean into a stage for these gentle giants. On the downside, it’s a relatively short tour — just an hour — so if you’re after a longer or more in-depth outing, you might find this a bit fleeting. This tour suits travelers who crave authentic wildlife encounters and don’t mind a little night swimming in the dark with a guide at your side.

– Accessible for Most: Suitable for ages 7-73, with some physical requirements.

An Authentic Nighttime Adventure: What to Expect
When you arrive at Keauhou Boat Harbor, you’ll meet at the public restrooms just past the boat trailer parking — a simple, straightforward meeting point. Once aboard the boat, your guides will give you a quick briefing on safety and what to look for, setting the stage for what’s to come. The boat ride itself is generally smooth, with the primary goal being to reach the manta feeding grounds a short distance offshore.
As darkness falls, the guides turn on special bright lights, which serve a dual purpose: they attract plankton, which in turn draws the mantas, and create an eerie, luminous glow in the water. This lighting is crucial because it allows you to see the mantas coming up close — sometimes within just a few feet! The guides will instruct you on snorkel use and safety, ensuring everyone feels comfortable swimming in the dark.
Once in the water, you’ll marvel at how gracefully these enormous creatures move. The mantas, which can measure between 12 to 16 feet across, perform slow, mesmerizing somersaults as they filter plankton through their large mouths. The experience of seeing them so close — and sometimes even beneath you — is unforgettable. One recent reviewer described the experience as “one of a kind,” with the team going above and beyond to make it special.

What makes this tour stand out is the surreal quality of the sighting. As Herbert from the U.S. put it, “The team with Sarah and Matt were outstanding,” highlighting how knowledgeable guides elevate the experience. The manta rays’ otherworldly appearance — with their paddle-shaped fins and large mouths — looks almost alien, yet peaceful. Their gentle, slow movements create a kind of underwater dance that’s both calming and exhilarating.
The guides do everything they can to make sure everyone has a good view and feels safe. They also provide high-quality masks, snorkels, wetsuits, and flotation devices, so you can focus on enjoying the show without worrying about gear. The entire process, from arrival to departure, is designed for maximum comfort and adventure.
