At night starting at eight there is a light show projecting a video onto El Castillo. The show is free, but you should register for it before in one of the Yucatan municipals and then order and print your ticket online. Otherwise you'll have the risk to not get a place or at least stanf in line a long time. It takes places in the center of the ruins. There's a light show while a video is projected onto El Castillo and a narrative in Spanish (headsets for other languages are available for a small fee (M$25 in August 2008)). The show lasts around an hour (half hour getting seated, half hour show) and while it may not be the most exciting (to some), on a nice night it is a pleasant way to relax, watch the stars and see the ruins lit up. They tell a great tale, which is very well done. If you can plan to be there at a "full moon" or a clear night with all the stars, it will be worth the effort, add to the experience and photographic results.
El Castillo
The most famous landmark of Chichen Itza. This was a temple-pyramid dedicated to the Feathered Serpent God, Kukulcan. It is nicknamed "The Castle". Sculptures of the Feathered Serpents run down the sides of the northern staircase, and are set off by shadows from the corner tiers on the Spring and Fall equinox. (Since 2006, you can not climb El Castillo.).
circular temple on a rectangular platform, also sacred to Kukulcan, served as an astronomical observatory. .
palace with hieroglyphic inscriptions.
Where a large selection of ancient pottery and idols may be seen still in the positions where they were left in Pre-Columbian times.
Beautiful cenote where you can jump from the "cliff" into the sparkling waters. Changing rooms, showers, lockers available. About 3 km from the archaeological site.
