One of Cozumel's advanced dives sites, mostly because of the boat ride. The site is very far south, even past Punta Sur (the south point of the island), and can be a very choppy ride as you cross over the area where the open sea meets the semi-protected channel. Once past the "mixing area" as I call it the seas usually calm down some, but it can still be a choppy entrance.
Once you manage to get underwater it's all worth it, this is a beautiful dive! The dive site is a pristine reef system layed out in parallel finger like ridges moving slightly off perpendicular to the island. One of the most untouched reefs on Cozumel, Chun Chacaab is teeming with turtles, in April of '08 I made 2 dives in a week there and saw no less than 6-8 Hawksbill turtles on each dive.
I also ran accross a 'school' of mature trunk fish, each well over 6" long, hanging over one reef head. In one of my photos I counted 15 of these shy creatures one usually finds in a solitary existance.
Currents can be heavy, but discuss this with the divers on board and if everyone cooperates, it's easy to drop down into crevices and between coral heads to get out of the current and do some exploring without getting too seperated.
