As the most famous of the Mayan pyramids on the Yucatán peninsula, Chichén Itzá has been studied extensively and is the most popular Mayan ruin in México. Much has been written about it. Try to visit Chichén Itzá early in the morning or late in the afternoon, as the sun can be punishing at midday.

The main attraction is the central pyramid, also known as El Castillo, this spectacular, massive Mesoamerican step-pyramid that dominates the Chichen Itza archaeological site in the Mexican state of Yucatan. Today El Castillo is one of the most popular and recognized tourist sites of Mexico and as of 07/07/07, it is one of the Seven New Wonders of the World. Built by the Maya sometime between the 1000 and 1200 AD, El Castillo served as a temple to the god Kukulkan and is believed to have served as a calendar. Each of the structures four stairways contains 91 steps. When counting the top platform as another step, in total El Castillo has 365 steps, one step for each day of the year. The structure is 24 meters tall (78 feet), plus an additional 6 m (20 feet) for the temple top for a total height of 30 meters (98 feet). The square base measures 55.3 meters (181 feet) across. Huge sculptures of plumed serpent’s heads sit at the base of the pyramid on the northern staircase. At sunset during the spring and autumn equinoxes triangle shadows are formed by the platforms making it appear as if a plumed serpent is descending the pyramid.

At the entrance to Chichén Itzá, there is an informative museum, a dining room, clean restrooms, a few gift shops, and vendor stands. If you didn’t bring a hat, it’s a good idea to buy one from one of the vendors outside before you go in.
