Teotihuacan is the main ruins site of near Mexico City. It was built by the Aztecs and has been pretty well preserved for tourists. You can hire a guide for an entire tour since there is not much information available once you get there. Visiting it entirely would take you about 2 hours. Buses depart for the North Terminal every 30 minutes and the entrance cost about $4. Don’t forget to bring a hat, sun screen and go in the morning to avoid the crazy Mexican sun. #history #views #climbing
