This is the group to go with if you have any interest in seeing manta rays! Diego, Danny, and Bryce were professional, friendly, and extremely understanding.
I have only done swimming lessons, and it was my first snorkeling, let alone in the pitch black! They support you as much as possible and guide you through what to do if you are and aren't comfortable. We saw two (possibly three?) LARGE manta rays and large amount of fish. The pictures you saw, Diego took and shared with the group. Such great momentos to a once in a lifetime experience. I recommend this group highly!!
