The state is located about 300 miles (483 km) from Mexico City.
It covers 5,471 square kilometers (2,112.4 sq mi) and has a little more than one million inhabitants. The state is not heavily populated. However, most of its inhabitants live in the densely populated metropolitan area of its capital city.
Although this state is not often billed as a tourist center, international visitors, as well as citizens from all over Mexico, are attracted to the San Marcos Fair, which is considered the national fair of Mexico and contributes much to Mexico's economy.
Recently, its capital city has gained the reputation as a great destination for its superb colonial architecture visible in the colonial centre, as well as the modernity and dynamism in the outskirts.
The city also hosts many conventions every year. It benefits from its excellent central location. The city is also famed for its environment of relaxation, and for its safety and cleanliness, as it is often described by people when traveling to this part of the country for conventions or tourism.
Most tourists go to the capital. A few tourists explore the former mining towns in the north of the state (in the municipalities of Asientos and Tepezalá), which are now almost ghost cities. The haciendas, hot springs, and baths scattered around the state are also of historical and recreational relevance.
