Having been to the big island multiple times through out the years, I have always wanted to do the Manta Ray snorkel trip but for reasons beyond my control, I was never able to do it until now. What an experience!! I HIGHLY recommend Coral Reef Adventures as our group size was small and we had personalized attention paid to us. Our tour guide, Jacob and Captain Marc were friendly, knowledgable, and made our trip not only fun but also a once in a lifetime experience. This is a must do!
