This was a once in a lifetime experience! I have been swimming with many kinds of rays in many parts of the world, but this was next level stuff! The GIANT (12ft+) creatures are magnificent and get up close and personal while bathed in a pleasant blue/purple glow of the lights. Watching them feed gave an opportunity to see every part of the rays, as they did acrobatics to fill their mouths with plankton. Gentle, majestic animals and a fun boat ride with Capt David & his crew. Highly recommend this - apparently Kona is one of the few places you can have this experience.
