You will have a 45 min ride by ferry boat from the Cruise Port, since you need to reach Playa del Carmen, which is on the mainland in front of Cozumel. Xcaret Eco-Archaeological Park is a really amazing place full of experiences beyond any expectation. There's a lot to walk, to see and to experience. It offers an aquarium section with fish, turtles, manatees; a zoo section with deer, jaguars, crocodiles, tapirs, a bird aviary, a butterfly pavilion and more! If you like to swim there's a natural salt water pool by the sea, or a beach where to snorkel as well. Moreover a river runs from one end of the park to another; you can swim through its mangroves and caves. Finally additional activities include swimming with dolphins, speedboat and more!
