What it is

Manta Ray Dives of Hawai‘i is a tour operator based in Kailua-Kona on the Big Island of Hawai‘i, specializing in nighttime encounters with manta rays. The company offers guided boat tours for both scuba divers and snorkelers to a designated manta ray viewing site. During these tours, powerful lights are used to attract plankton, which in turn draws manta rays to feed, allowing participants to observe them up close.

Visitor experience

Travelers choose Manta Ray Dives of Hawai‘i for the unique opportunity to witness manta rays feeding in their natural habitat at night, an experience often described as magical and exhilarating. The tour caters to a wide range of visitors, from certified scuba divers looking for an extraordinary night dive to snorkelers who wish to float on the surface and watch the mantas from above. It's an ideal activity for wildlife enthusiasts, photographers, and those seeking a memorable and awe-inspiring marine encounter. The experience is suitable for families with children who meet age and swimming requirements for snorkeling.

Logistics

The tours depart from Honokohau Small Boat Harbor (Kona Marina) in Kailua-Kona. The address is 74-380 Kealakehe Pkwy slip c-01, Kailua-Kona, HI 96740, USA. Access to the harbor is straightforward from the main highway. Reservations are highly recommended, especially during peak season, as spots can fill up quickly. Tours typically take place after sunset, with specific departure times varying seasonally. Participants are usually advised to arrive at the meeting point 30-45 minutes before departure for check-in and briefing. Parking is available at Honokohau Small Boat Harbor. The entire experience, including check-in, boat ride, in-water time, and return, generally lasts approximately 2-3 hours, making it an excellent half-day or anchor evening activity. No special permits are required by visitors as the operator handles all necessary permissions for the tour.

Safety and cautions

Participants should be comfortable in the ocean at night and be able to swim unassisted for snorkel tours. For scuba dives, certification is required. All gear (wetsuits, masks, snorkels, fins for snorkelers; full dive gear for divers) is typically provided by the operator. It's common for operators to provide thorough safety briefings before entering the water. Weather and ocean conditions can affect tours; cancellations due to rough seas or high winds are possible for safety reasons. Guests prone to seasickness should consider taking preventative measures before the boat ride. It is important to maintain a respectful distance from the manta rays and avoid touching them, as per wildlife viewing guidelines and local regulations. Sunscreen use should be reef-safe to protect marine ecosystems.

Editorial take

This manta ray encounter is a signature Big Island experience and should be prioritized by most visitors to Kona, particularly those interested in unique wildlife interactions and ocean activities. It's suitable for both adventurous scuba divers and snorkelers, making it accessible to a broader audience. Those who are highly uncomfortable in open water, at night, or prone to severe seasickness might consider skipping it, although the experience is typically in calm, protected waters. It should not be confused with daytime snorkeling or diving, as the nighttime aspect with the feeding mantas is what makes this experience distinct. Other operators offer similar manta ray tours, so comparing amenities, group sizes, and departure locations may be beneficial for travelers.
