Well being in Mexico I know Chichen Itza is a great place. The coolest place is the giant pyramid that has been nominated a new wonder of the world. It is giant. A step for each day of the year (Normal) and a cool thing is you can talk normally at the top and people on the bottom can hear you. The cenote is ok. Very green water and the length from ground is cool. Several other pyramids are there. Also there is a tunnel that you can go through but it’s pitch black. At the end there is a gift shop where you can buy things from Chichen.
