Constitution Plaza, also known as Zócalo, is a vibrant and historic hub in Mexico City, offering travelers a rich cultural experience. Easily accessible via the city's extensive public transportation system, particularly the Zócalo Metro Station, it is ideal for both solo exploration and guided tours. Visiting the plaza, which is one of the world's largest city squares, is free, though costs may arise if you join organized tours or visit nearby attractions like the Metropolitan Cathedral or the National Palace. Plan to spend a few hours here to fully take in the surrounding architectural marvels and bustling activity. Seasonal festivities, especially during the Día de los Muertos in late October and early November, make it an exceptionally lively time to visit. Daytime visits are recommended for safety and to appreciate cultural performances and events that often take place in the plaza.
