La Guelaguetza, alternatively called Los Lunes del Cerro (Mondays on the Hill), is one of the biggest annual cultural festivals in all of Mexico. It is held at the Guelaguetza stadium in Oaxaca City on the last two Mondays of July. During this festive time, all the villages in Oaxaca come together to celebrate their regional styles and Oaxacan indigenous culture through food, mezcal, and dancing in front of thousands of people. Food plays such an integral role in this tradition, as foods like tortillas and sacks of beans are thrown into the crowd after each performance. If you love people and love to party, I recommend that you visit Oaxaca during this time of year.
