Visit Chichen Itza, Mexico
The most famous and best restored of the Yucatán Maya sites, Chichén Itzá, while tremendously overcrowded – every gawker and his or her grandmother is trying to check off the new seven wonders of the world – will still impress even the most jaded visitor. Many mysteries of the Maya astronomical calendar are made clear when one understands the design of the ‘time temples’ here. Other than a few minor passageways, climbing on the structures is not allowed.
