This was the coolest thing we did on the big island. The manta rays are amazing. You’re not allowed to touch them, but they can and will definitely touch you! Our captain, Simon was so informative and hilarious. The two crew members were also amazing and super helpful while in the water. I will say that if you easily get seasick, watch the water conditions when you go. We went in late February, the water was a little rough and there were at least 6 people vomiting on the front of the boat while we were parked. It was pretty rough in the water too, we were jerked all around while hanging on to the floating lights. Even so, it was WELL worth it!
