Mexico contains 32 federal entities spanning 1,964,375 square kilometers between latitudes 14°N and 33°N. The country shares a 3,145-kilometer border with the United States to the north and borders Guatemala and Belize to the southeast. Three primary mountain ranges—the Sierra Madre Occidental running parallel to the Pacific coast, the Sierra Madre Oriental paralleling the Gulf of Mexico, and the Sierra Madre del Sur extending through southern states—create geographic barriers that have produced distinct regional identities. The Trans-Mexican Volcanic Belt, stretching east-west across central Mexico at approximately the 19th parallel, contains the country's highest peaks and divides the nation into northern and southern climate zones. This volcanic axis hosts Pico de Orizaba at 5,636 meters, making it the third-highest peak in North America, along with the active Popocatépetl at 5,426 meters and the dormant Iztaccíhuatl at 5,230 meters. The geography creates seven distinct travel regions with minimal overlap in ecosystems, architectural styles, and culinary traditions.
The Yucatán Peninsula extends approximately 300 kilometers into the Gulf of Mexico and Caribbean Sea, separated from central Mexico by over 1,000 kilometers of mountainous terrain. The peninsula's limestone geology creates thousands of cenotes—sinkholes providing access to underground rivers—with Cenote Dos Ojos containing over 80 kilometers of surveyed underwater passages and Cenote Ik Kil descending 26 meters to water level with a 60-meter-wide opening. Chichén Itzá, occupied from approximately 600 CE to 1200 CE, features the Pyramid of Kukulcán rising 30 meters with 91 steps on each of four sides totaling 365 when the top platform is included.
