Shark Ray Alley is a part of the Mesoamerican Barrier Reef, the 2nd largest reef in the world after Australia’s Great Barrier Reef. As the name implies, there are loads of sharks and rays in this part of the reef. The sharks and rays here are quite used to people and will come to boats as they pull up. The staff then drop a tube of food into the water and the sea creatures go into a feeding frenzy right in front of your eyes. It’s quite amazing!!
