A number of facilities offer the opportunity to swim with dolphins right in Cancun. For land adventures, the best idea is to book a self-drive Jeep tour. It’s good to hire an experienced guide who can lead you through the twisting jungle paths and show you the most interesting underground caves and lakes, and guide you through the impressive Mayan ruins. Jungle reserves in Cancun have an incredible variety of wildlife, including tropical birds, monkeys, jaguars, and reptiles. Surprisingly, one of the best places to find tropical birds is in the Cancun airport, owing to its fairy-tale location carved into the island jungle.
