Still in awe of the manta rays!

"What a great night! We just came back from a night snorkel with enormous manta rays and it was magical! Nice boat, fantastic sunset, great people and some nice information about the mantas. We watched the mantas in a calm en quiet place with just 2 other boats, really relaxed and close by! We really loved our trip and would recommend Adventure X Boat Tours to everyone! Thank you Captain John and Lorraine for this amazing experience!! It was the best!!"

THE BEST IN HAWAII

"WOW. My family and I went on the Manta Ray tour last night and we were all left speechless. It was by far the most amazing experience all 9 of us have had in our lives! It was so spectacular that I would pay to do it over and over again. We even had a few family members who were scared to go in the water, but the amazing crew put them at ease. Captain Casey, Jenna, and Kayla made our experience better than we ever could have dreamed. I have recommended this to every stranger I've passed since on the island, because everyone should experience this at least once!"
