Chichen Itza is one of my favorite archaeological ruins. The Mayans were such a fascinating and advanced society. I could write a whole paper about this site! (Actually I did write a paper about this site in my undergraduate days. The paper focused on osteological evidence for human sacrifice found in the sacred cenote.)
Ahh . . . the romance is still alive! When we came here several years ago we walked up the steps of the large pyramid, but they don't allow tourists to do that anymore.
