Thursday, Friday, Saturday, and Sunday between 8 and 9 pm, Callejoneadas (mobile musical parties) begin in front of Teatro Juárez on Calle Sopeña, in the center of town. These quintessential, traditional tours are led by a group of student-minstrels, in full-out period costumes, who roam the narrowest streets of Guanajuato—the callejones—while strumming stringed instruments and singing folk songs, followed by the mass of paying customers, tourists from both Mexico
and abroad. For a small fee you can travel with the group while enjoying an alcoholic beverage of sorts. (It's usually some bad combination of grape drink and firewater—so we recommend bringing your own.) The important thing is to try to get in a smaller group in order to keep up and hear the commentary—which is in Spanish only. You'll see people selling tickets around the theater, and you should ideally pay no more than 100 pesos per person. A fun part of your night will be stopping on the Callejón del Beso, a street so narrow it's said that a kiss could be exchanged between secret lovers on top-floor balconies. Bundle up on cold nights; the tours last up to two hours.
