This UNESCO World Heritage Site is both the most significant and the largest pre-Columbian city in the country. Located 25 miles out of Mexico City, it was built around 100 BC and grew to be the home of more than 125,000 people. It includes residential complexes and many murals. The main attractions here are the Avenue of the Dead and the Pyramid of the Moon.
Unlike many remote ancient ruins, this particular Mayan site is actually in the hotel zone of the tourist district just outside of the popular, bustling city of Cancun. It is over 1,000 years old. Close to the Caribbean Sea, these ancient ruins include almost four dozen structures and feature ancient burial sites and murals.
