Fodor's Expert Review Jardín de la Unión

Guanajuato's central square is a tiny, tree-lined, wedge-shaped plaza bordered by pedestrian walkways. There are musical performances in the plaza's band shell Thursday at 6 pm and Sunday at noon; at other times, groups of musicians break into impromptu song along the shaded tile walkways. Strolling mariachis will perform, too—for a price. This is a great place to sit—on the wrought-iron benches or at an outdoor café—to enjoy the scene and to reconnoiter.
