Mexico has the largest number of UNESCO World Heritage Sites of any country in the Americas (31). The largest tourist draws are the archaeological sites of extinct civilisations, called Mesoamericanas. Guadalajara is the second largest city and where several of the best-known Mexican traditions began, such as tequila, mariachi music and charros (traditional horseman). One of the most popular destinations is Cancun, with its crystal blue waters. However, there are several other famous Mexican cities worth visiting, such as Los Cabos, Acapulco, San Cristóbal de las Casas, Chichen-Itzá, to name a few. Mexican food is popular worldwide: tacos, burritos, nachos, guacamole, chillies, enchilada, quesadillas, salsas, etc. Mexican gastronomy has actually been designated status as an Intangible Cultural Heritage by UNESCO. One warning though: Mexican food can be very spicy.
