Tulum Mayan Ruins
"Tulum is perhaps the best preserved coastal Mayan Ruins site and is the second most visited of all the Mayan ruins sites in Mexico. It is unique and special in several ways. The ancient city of Tulum is about 800 years old, being abandoned by the end of the 1500s. Surrounded by walls, Tulum served as a fortress against enemies approaching by sea, and was also a major trading port for the inland city of Coba. Tulum is perched on a lookout atop a 40' sheer cliff, creating a drastic and awesome view of the Caribbean Sea from it's grounds. It's the kind of view that you'll remember forever".
A 45 minute boat ride (known for rough waters to where the ruins were located) from Couzmel, Mexico) - Fortunately it was relatively smooth on my voyage to the ruins. (: > )))
An amazing sight.. Great history.
