When you think about history and Mexico there are a few locales that come to mind. The one that really stands out is the area of the Yucatan peninsula that encompasses the area once dominated by the Mayan people and where you can still find incredible evidence of their advanced civilization. Just a short drive from the high-octane resort towns of Cancun and Cozumel are examples to be found of the height of Mayan architecture and civilization.
Many travel providers can set you up with tours that will let you enjoy and explore several archeological sites and still put aside time to lounge on a beach to soak in the sun. This gives you the opportunity to have an educational experience as well as a relaxing vacation. Spend a few days traveling to several of the most well known ruins and then kick back with some typical water activities.
