The entire experience from start to finish was incredible. Simon and his crew provide the most enjoyable tour experience that I've ever had, they love what they do and it shows in the tour. The manta rays themselves are also amazing. The rays continuously swim inches away from you throughout the session. I've been to Big Island three times with three different sets of friends. Every time I've been on the island, I've taken my friends on this tour and they've all had a great time. I highly highly encourage people to see the manta rays while on Big Island and to book with this tour company, as they make the experience one of a kind.
