Tourism in Mexico is a huge industry. Mexico has traditionally been among the most visited countries in the world according to the World Tourism Organization, and it is the second-most visited country in the Americas, after the United States. The most notable attractions are the Meso-American ruins, cultural festivals, colonial cities, nature reserves and the beach resorts. The nation's temperate climate and unique culture – a fusion of the European and the Meso-American – make Mexico an attractive destination. The peak tourism seasons in the country are during December and the mid-Summer, with brief surges during the week before Easter and Spring break, when many of the beach resort sites become popular destinations for college students from the United States.
The majority of tourists come to Mexico from the United States and Canada. Other visitors come from Europe and Asia. A small number of tourists also come from other Latin American countries. There is also a burgeoning domestic tourism trade as a growing affluent middle class begins to go on holiday within their own country. While Mexico's middle/lower class usually promotes national tourism, the middle/higher class usually prefers to travel overseas.
Tourists from the United States began arriving in Mexico in numbers starting in the 1880s, following construction of direct railway lines in Mexico to the U.S. border. General Porfirio Díaz became president of Mexico by coup in 1876, the beginning of a long period of peace in Mexico following decades of civil war. With the inauguration of direct Pullman service from the U.S. to Mexico in 1884, tourists no longer endured difficult and dangerous travel. The Mexican Central Railway actively promoted tourism in the United States, hiring a professional photographer, William Henry Jackson, to visually record the route and a professional writer, James W. Steel, to write promotional copy. Guides for English-speaking tourists were also published, most notably Terry's Guide to Mexico, which went through several editions at the beginning of the twentieth century. Mexico appealed to American tourists seeking an "exotic" holiday.It was promoted in 1890 as the "Egypt of the New World." With the 1910 centennial of Mexican independence, the government undertook an excavation and reconstruction of the Pyramid of the Sun at the huge archeological site of Teotihuacan, near Mexico City. A railway line was constructed from the capital to the site, bringing scholars from the 1910 meeting of the International Congress of Americanists. In addition, the National Museum of Anthropology was refurbished in advance of the celebrations, in anticipation of tourists. Mexico was a beneficiary of the increasing tourism of Europeans and Americans to distant lands. In Mexico, many tourists brought home real or fake relics, and often left graffiti.
