Start your journey in Cancun, Mexico. The Chichen Itza sites are only a short drive away.
Go early. The temples and pyramids get busy, as they are popular tourist sites.
Make sure to see El Castillo and the Temple of the Warriors. These structures are two of the most important and stunning Mayan constructions.
Take your trip on the vernal equinox (March 20 or 21) or the autumnal equinox (September 20 or 21). El Castillo is famous for the sun casting shadows of serpents upon its steps at these two times.
Take a guided tour. These tours will allow you to see the sites in a structured and very informed way.
