1. Chichén Itzá
As the most famous and best restored of the archaeological Yucatán Maya sites, Chichén Itzá is a must-see for all visitors to Cancún. The 6.5km sq site is considered to be one of the New Seven Wonders of the World, with the spectacular Pyramid of Kukulkan and the 25 metre-long calendar stone real highlights.
If you visit during the spring equinox, March 19-22, watch out for the moment when the sun creates the illusion of a feathered serpent god descending the stairs of the Pyramid of Kukulkan – one of the great sights of the world. But whenever you go, make sure you stick around for the nightly sound and light show.
