I have searched through the boards and found Chankanaab park to be the most recommended place to snorkel in Cozumel. Everyone refers to it as "good" or "nice"...I was able to find some underwater pictures on the net and it doesn't look that spectacular for snorkeling. The shots I have seen show some beautiful fish, but not much else...the ocean floor is just sand. I have seen some pathetic examples of coral as well.
My question is: If we want to have the best possible snorkeling experience...is this really THE place to go? If not, does anyone have any recommendations?
