Mayan Worlds

Cancun, Mexico. Evidently, there may not be much time left. According to the Mayan calendar, a distinct end of a cycle will occur on Dec. 21, 2012.

Although it's not clear what cycle will be ending -- and although not fatalistic -- we decided it may be an opportune time to experience the Mayan world.

It seemed there wouldn't be any better way to explore this ancient civilization than by taking an interactive eco-adventure tour.
