I snorkeled this reef July 2012 3 times as well as dived the reef twice. Best one I found for ease of access and marine life. lots of turtles, lots of eels if you look for them, lots of fish. Eagle ray came by while I was diving 30ft at the end of the reef and the sand. I went with wife and friends who are beginner snorkelers and didn't go out as far, they loved it. Saw lots of turtles and fish. Hence the number of times we were back there. I didn't see any white tips, but was looking for them.
