With wide tunnels and cavernous rooms lit by natural skylights, Punta Sur is a favorite dive of Cozumel veterans. Devil's Throat is the famous underwater subway tunnel that takes you from the top of the wall at 80 feet through a sun-dappled ballroom and deposits you in the channel at 130 feet where eagle rays and sharks occasionally cruise.
