What an incredible experience! Even better than I imagined. Kekoa, Peyton and Tako were the crew that took care of us and they were amazing! They were great to make us feel at ease and to explain things. The manta rays were beautiful and graceful. I didn't expect to see so many and that close up. I absolutely loved it and would definitely recommend My Kona Adventures!

This was a once in a lifetime experience. Some of my family was a little apprehensive about swimming at night, but the guides and the area eased that appreciation. Our guide Peyton was so informative and helpful about the manta rays. The manta rays were absolutely beautiful and the whole experience was like no other. We all fell in love with the manta rays, and my daughter even says this is her new dream job. 10/10 recommend even if you are scared. This is an opportunity you cannot pass up!

We had a wonderful time, saw many manta ray’s! Stunning, beautiful! Staff were helpful and friendly, I was a little nervous, they were patient and gave options to help me out!! The staff gave a little Hawaiian history of the area, which was very interesting! Excellent trip!

This experience was even more amazing than we expected. The whole crew was fantastic and steered us through a surreal adventure. The manta rays were out of this world. Highly recommend this tour and specifically My Kona Adventures.

We had an absolutely incredible experience snorkeling with manta rays with Kona Adventures. It was truly one of the highlights of our trip. We saw 11 manta rays, and watching these beautiful, gentle creatures glide right beneath us was unforgettable. The crew was fantastic from start to finish—professional, friendly, and clearly passionate about what they do. Jenny was in the water with us, guiding the group and making sure everyone felt comfortable and safe while also helping us spot the mantas up close. The whole team created such a calm and exciting atmosphere. Everything was well organized and the crew made sure everyone had an amazing experience. If you’re visiting Kona, this is a must-do activity. Seeing the manta rays at night is magical, and Kona Adventures made it truly special

We went on the 9:50 pm manta ray tour and it was spectacular! We saw multiple mantas, they were very active bumping our legs and arms the entire time. It was our first trip to the Big Island. This is definitely a MUST tour. Our guides - Koa and crew were absolutely fantastic! See you next year!
