St. Patrick’s Day

Each year since 1968, our San Antonio River Walk is magically transformed into the River Shannon as the eco-friendly green dye is swirled into the water. 

This is an exciting time to visit the River Walk and watch the amazing transformation. A bagpiper plays on the barge as the river is transformed. FREE viewing is available along the entire 2 1/2 mile downtown portion of the River Walk. 

The color is instantly apparent and intensifies with water movement by the boats.  Additional applications create an even richer color.  Over the course of two to three days, the river goes from emerald green to turquoise green to a fluorescent green before it returns to normal.
