Self-Guided Podcast Tour: The San Antonio River Walk

About this activity

Descend beneath the bustling streets of San Antonio into a subterranean world of stone staircases, lush cypress trees, and engineering wonders. This tour unveils how a deadly flood in 1921 nearly led to the river being paved into a concrete sewer—until a theatrical puppet show, a visionary architect, and New Deal funding transformed an urban hazard into an iconic linear park.
