We had a once in a lifetime experience snorkeling with the manta rays and Aloha Kona Tours! Captain Koichiro was amazing. He has a beautiful luxury boat. Julia was our snorkel guide. She is a marine biologist and very knowledgeable. She shared lots of facts about the manta rays and other sea life. We saw tons of manta rays. They circled around us and did belly rolls. It was spectacular! Julia made sure we were in the right spot for the best viewing. Captain Koichiro served us fruit on our trip to the site and had hot cocoa waiting when we finished our snorkel! He was very respectful, knowledgeable, and a wonderful captain! He also took the time to take a photo of our family in front of the sunset which was so thoughtful. We loved our experience with Captain Koichiro and Julia!! They are the BEST!!
