Make your way to the tour offices on Honokohau Harbor in Kona, where you'll check in and get fitted for gear. Hop on your tour boat and head out to sea; your spacious vessel is equipped with a top observation deck, a large cabin, and an onboard bathroom.
Reach your destination in time to watch the colorful Kona sunset from the boat's top deck, then start getting ready for your manta ray encounter. Slip into your wetsuit, don your snorkel, and jump in. Buoy yourself with a flotation device; your guides will set up lights to see the mantas clearly.
Spend about 45 minutes snorkeling using a customized light board with one of the brightest lights in the water, showcasing the graceful ballet of the giant mantas as they careen through the water in search of food. You'll be in 30 to 35 feet (9 to 10 meters) of water, within sight of the shoreline, and supervised by your experienced guide to ensure your comfort and safety. Manta rays have no barbs or teeth, a wing span of 4 to 12 feet (1 to 4 meters) and weigh between 400 and 1200 lbs (180 and 545 kg). Interactions with the manta rays take place in a passive, respectful manner.
Manta sightings are guaranteed, or you will be given a voucher for another tour.
