This tour promises a combination of stunning wildlife encounters and a sense of wonder that’s hard to find elsewhere.
What really draws us in is how close you’ll get to these enormous creatures—some measuring up to 16 feet across—in their natural environment. Plus, the fact that it’s a guided experience with good gear and clear instructions means you can focus on enjoying the moment without stressing over the technicalities. On the flip side, it’s a night tour, so you’ll want to be comfortable with swimming in low light and potentially cooler waters.

What Is the Keauhou Bay Manta Ray Night Tour?

This night tour from Keauhou Bay offers an incredible chance to see manta rays in their natural habitat at night. The experience is centered around observing these gentle giants, known for their enormous size and elegant movements, as they gather in large numbers to feed on plankton attracted by the tour’s bright lights.
During this tour, you’ll board a boat, usually in the early evening, and be guided to a prime spot where bright lights are used to lure the manta rays closer. The highlight is watching them perform slow, mesmerizing somersaults, sometimes coming remarkably near to snorkelers—an experience that’s as surreal as it sounds.
The Experience Itself

The tour lasts around one hour, so it’s a fairly quick but dense session. You’ll meet at the Keauhou Boat Harbor, just past the boat trailer parking, at a designated spot near the public restrooms. Guided by friendly and knowledgeable staff, you’ll receive instructions on how to snorkel safely and effectively, ensuring everyone gets the most out of the experience.
Once in the water, the guides will help you with good quality masks and snorkels, along with wetsuits and flotation devices. Swimmers need to be comfortable in water and capable of climbing the boat ladder unaided, but there’s no need to be an expert swimmer. The guiding team, including the reviewer’s mention of outstanding guides like Sarah and Matt, will support you along the way.
Expect to see manta rays performing their “underwater ballet”—slow, majestic movements that look almost hypnotic. Their large, unique mouths and paddle-like fins are fascinating to observe, especially as you get a glimpse inside their mouths and through their gills.
Why It’s Special
What makes this tour stand out is the combination of proximity and natural behavior. Unlike other wildlife encounters, here you’re not just watching from a distance—you’re right there with the rays, witnessing their graceful acrobatics in a setting that feels both magical and untouched.
The guides’ expertise adds significantly to the experience. As one reviewer noted, “The team with Sarah and Matt were outstanding,” highlighting how helpful and knowledgeable the staff are. Their understanding of manta behavior and the environment helps heighten the experience, offering insights that make the encounter even more meaningful.
