Baja California – provides some of Mexico’s most dramatic sea and landscapes. This includes everything from vast and remote deserts, dormant volcanoes, and wonderful old mission towns.
Northern Mexico – is a vast desert region bordering the United States of America. The north is sometimes referred to as “unknown Mexico” or “lost Mexico” because it is ignored by the vast majority of tourists.
Bajío – A rich silver-mining area in the 17th and 18th centuries, the Bajio saw an explosion of fabulous wealth for the time, and the cities there grew to be large and spectacular. They retain their amazing architecture and traditions, however, making them a joy to visit (*Guanajuato or *San Luis Potosí).
Central Mexico – always the political, cultural and economic center of the country. Also includes the awesome ruins of *Teotihuacan, the historic city of *Puebla and *Veracruz, one of the country’s most overlooked regions.
Pacific Coast – Tropical beaches on Mexico’s southern coast; *Jalisco (map) the birthplace of mariachi and Tequila; *Guadalajara (map), the nation’s second largest city; and the *Oaxacan highlands, famous for their distinct cuisine.
Yucatán and the South. The *Yucatán was the home of the Maya civilization before it was conquered by the Spanish Conquistadors in the 16th century. *Quintana Roo (map) – heavy tourist traffic is lured to the northeast of the state, notably by the infamous party city of Cancún, but also by the endless gorgeous Caribbean white sand beaches, some of the world’s greatest scuba diving, beautiful cenotes, and a few excellent Mayan sites.
Stay in populated areas, avoid poor neighborhoods, especially at night, and don’t walk there at any time if you are alone.
Some parts of Mexico are known for travelers’ diarrhea, often called “Montezuma’s Revenge” (Venganza de Moctezuma). The reason for this is not so much the spicy food but the contamination of the water supply in some of the poorer zones in Mexico.
