Ciudad Perdida Archaelological Park.

Also known as Teyuna, is on the Buritaca River in the Sierra Nevada de Santa Marta mountain range. Ciudad Perdida, which means "lost city," is not easy to get to but visitors can enjoy the beauty of exotic forests, waterfalls and hanging bridges on the way. Discovered in the 1970s, Ciudad Perdida was built in A.D. 700 as a city of the Tayrona Empire. Visitors who make the jungle trek to Ciudad Perdida will see about 200 terraces built for living spaces, streets, paths, aqueducts, a sewage system and other aspects of life in the ancient city.
