About this tour
The River Walk feels inevitable now — cypress trees, cafe tables, boats gliding a level below the street — but it exists because of a disaster. A catastrophic flood tore through downtown San Antonio in September 1921, killing dozens of people, and the city's first serious proposal afterward was to pave the river over as a concrete storm drain. This walk traces that argument from its oldest evidence to its final answer: a colonial-era creek tied to the flood story, a 250-year-old river crossing, a museum built directly on the water, the River Walk's first restaurant, and the open-air theater that proved the river was worth saving as a park instead of burying as a pipe.
