Underground Streets

Guanajuato’s underground streets form a unique road system beneath the historic city center. Originally built as flood-control channels, these tunnels were later adapted for vehicle and pedestrian use. The tunnel network helps reduce surface traffic while preserving the historic appearance of the city above. Walking or driving through these underground passages is a distinctive experience found in very few cities. For travelers, the underground streets offer insight into Guanajuato’s urban design and history. They also provide practical routes between different parts of the city.
