Amy, we've been to 3 Mayan sites near Cancun - each of them quite different. I think this is the best place for me to share images and pictures with you. Unfortunately, it's an old blog template and the space for photos is narrow and cuts them off or forces me to minimize them. Maybe you can click on the pictures to enlarge(?).
CHICHEN ITZA
The first time we were in Cancun (2007) we went to Chichen Itza ("chee-chin eetz-uh"). It is a site that has been restored and is being significantly maintained. I remember it being the largest of the sites we saw, but then again it's been 14 years ago, so maybe my memory is fuzzy! We had a guide, and we learned a lot. A year before we got there people were still allowed to go up the steps of the Great Pyramid, but that is no longer allowed, unfortunately. It is a Unesco World Heritage Site, and, as well as the Great Pyramid it also has a temple complex, a "sports arena," a large cenote, and other features. I don't have as many pictures of Chichen Itza as of the other two sites, as I don't think we had a digital camera in 2007, so these are scans of photos.
