Escape the busy crowds of Cancun and head to the peaceful Isla Mujeres or Island of Women. You can reach the island by using one of the ferry boats, and the trip will take you just over 20 minutes. There isn't much to do on the four-mile-long island, but it is still a popular day trip. Head to Punta Sur and visit a Mayan temple that was dedicated to the moon goddess. You may want to visit one of the local turtle farms to spend time with these interesting creatures and find out more about them.
