Experience up-close manta rays at night in Kona with this 2-hour snorkel tour, led by knowledgeable guides, including gear and wetsuit for $69.99.
The Manta Ray Night Snorkel at Kona offers a captivating glimpse into the ocean’s gentle giants for just $69.99 per person. Set in Keauhou Bay, this 2-hour adventure is led by experienced guides who know the best spots to observe manta rays feeding after dark. The tour includes short-sleeve wetsuits and snorkeling equipment, making it accessible for most swimmers, with a focus on safety and close encounters. Reviews highlight the close proximity to manta rays and the know-how of guides like Bryce, making this a top-rated experience with a 5.0/5 rating from over 1,300 reviews.
While the experience is thrilling, it’s best suited for active swimmers aged 6 and above who are comfortable in the water. Physical fitness and the ability to climb a metal ladder are required, but the tour’s safety measures and knowledgeable crew help ensure a memorable, safe encounter. Expect a short boat cruise, a roughly 30-minute in-water observation, and plenty of chances to see multiple manta rays in their natural habitat.


The tour departs from 78-6831 Alii Drive, Kailua-Kona. Guests should arrive 15 minutes prior to the check-in time, which is an hour before the boat departs. The check-in process takes place at a different location than the boat launch, specifically at the Dolphin Discoveries facility. Clear directions and signage help, but arriving early is recommended to avoid missing the boat due to parking or navigation challenges. The boat itself offers a short 5-minute cruise from the dock into Keauhou Bay.

The tour begins with a brief cruise across the Pacific Ocean toward the manta feeding grounds. The vessel can comfortably accommodate up to 28 guests, allowing for a personal yet lively atmosphere. The boat is equipped for safety and comfort, with crew members prepared to facilitate a smooth transition into the water. Most guests find the boat ride relaxing, with scenic views of the coastline as they head toward the prime snorkeling zone.

Once in the water, guests hold onto specially designed rafts that assist in viewing the manta rays feeding beneath and around them. The in-water time lasts approximately 30 minutes, during which multiple manta rays are likely to approach, sometimes within arm’s reach. The rays are peaceful creatures that feed on plankton, and their majestic, slow movements create an almost hypnotic scene. The best viewing spots are in the bay, where the rays gather to feed at night.

Knowledgeable guides lead each group, providing insights into manta ray behavior and safety instructions. Guides are praised for their professionalism, friendliness, and attention to detail. They ensure everyone knows how to use the snorkel gear and hold onto the rafts securely. Physical fitness is necessary, and swimmers must be able to climb a metal ladder to reboard the boat. Guides keep the atmosphere safe and relaxed, managing rough seas and individual needs effectively.

The tour includes short-sleeve wetsuit tops and snorkeling equipment, simplifying the packing process. Guests are advised to bring a towel for after snorkeling, as the boat does not have restroom facilities onboard. Gratuities are appreciated for the crew, especially those in the water who work hard to create memorable encounters. Photography is encouraged, with many guests opting for their GoPro or underwater camera to capture the moment.

Participants must know how to swim and tread water comfortably. The tour is not suitable for individuals with neck, back, or medical conditions, or those who weigh over 285 pounds. The climb onto the boat’s metal ladder is a requirement, so guests should be comfortable with this task. The tour’s physical demands and safety measures make it best suited for active individuals with moderate fitness levels.

Many comment on the up-close encounters with multiple manta rays, sometimes seeing seven or more at once. Guests mention feeling safe and well looked after, even amid rocky seas or challenging navigation. The visual spectacle of manta rays feeding beneath the surface is described as breathtaking, with many noting they would recommend this experience to others.
Some reviewers mention the challenges in finding the meeting location and parking, emphasizing the importance of arriving early and allowing extra time. The lack of restroom facilities on the boat is noted, but most agree that the viewing experience outweighs this inconvenience. The tour receives high praise for value, safety, and memorable interactions with these gentle ocean creatures.

This tour offers a unique chance to witness manta rays feeding in their natural environment at a very reasonable price. The inclusion of snorkel gear and wetsuits adds to the value, especially given the high quality of guides and the intimate nature of the experience. While no refunds are available if manta rays do not appear, the likelihood of seeing multiple rays makes the risk worthwhile.
For anyone seeking a close-up, safe, and informative encounter with manta rays, this tour stands out as an exceptional choice. Its positive reviews consistently highlight the knowledgeable guides, stunning sights, and overall sense of adventure.
