Further down the coast from Xel Ha are the Mayan ruins at Tulum. Joanne and I had been here about five years ago. Joanne says they've updated it a lot and improved the accessibility to the sites.
This pyramid is at Chichen Itza (pronounced 'cheechin eat-sah'). This area, also in the Yucatan peninsula but inland, is one of the most extensive Mayan ruins sites in the world.
This is a detailed shot of a snake head carving at Chichen Itza. The snake body is the edge of the steps. Joanne's tour guide told them that at solstice time in the spring and fall, the sun hits the steps just right to make it look like the snake bodies are slithering. Joanne and Jennifer missed the solstice by about a week.
