Mexico is one of the most popular tourist countries on earth. Much of the tourist industry is centered around the beach resorts as well as the altiplano in the central part of the country. Visiting the northern interior allows visitors to get off the beaten path a bit. American tourists tend to predominate on the Baja peninsula and the more modernized beach resorts (Cancún, Puerto Vallarta), while European tourists congregate around the smaller resort areas in the south like Playa del Carmen and colonial towns like San Cristobal de las Casas.
