This tour is the most "worth it" tour I've ever taken. When you take tours involving wildlife, you're always worried they'll be no-shows, which has happened to me before. But there were SO many manta rays, & they were HUGE! They were doing backflips in the water & coming up so close to us that one touched me. It looked like they were doing tricks in the water, but apparently that's just how mantas feed. It was like they were trying to put on a show for us. I can't even put into words how beautiful they are or how incredible this experience was. My GoPro footage is insane. This is a must-do in Hawaii, & it's not scary at all. Lots of people were scared or nervous until they got in the water, & then they were just in awe. This tour also has more time slot options than other tours, which allows for so much for flexibility with your schedule. Jasmine was out here climbing & jumping & working hard to make the experience great, so tip your guides!
