Mexico's landscape is a living museum, where Olmec colossi stare across millennia and Aztec temples lie beneath modern streets.

From 3.5-billion-year-old microbes to Maya astronomical marvels, these five sites reveal civilizations that shaped the Americas—and still captivate travelers today.

Cuatrociénegas' Living Fossils

In the Chihuahuan Desert, the Cuatrociénegas Biosphere protects turquoise pools teeming with stromatolites—Earth's oldest lifeforms. These rock-like structures, dating back 3.5 billion years, helped create our oxygen-rich atmosphere. NASA studies them to understand early Mars.
