Words can not describe the manta ray experience. Our Captain, Simon, explained everything clearly, and got us to the location In less than 25 mins. We spent 45 mins in the water with the manta rays swimming within one inch, 2 centimeter of our face, they are beautiful, graceful and an experience one does not forget. We have done many great adventures on this island but the manta rays and Mouna Kea were definitely the most memorable.
