This is a must do when visiting the Big Island! The 12ft manta rays are gentle giants that came within a couple feet of my group. It was an awe inspiring experience like no other. Our tour guides made sure we saw manta rays, so we left our original spot 20 min North of the meet up site to travel South another 30 min. We saw 3 huge manta rays there, so it paid off!! Bring towels, as the boat ride back can be a little chilly. They provide snacks and waters. Bring your GoPro if you have one!!
