Zilker Metropolitan Park is a recreational area in south Austin, Texas at the juncture of Barton Creek and the Colorado River that comprises over 350 acres (142 ha) of publicly owned land. It is named after its benefactor, Andrew Jackson Zilker, who donated the land to the city in 1917. The land was developed into a park during the Great Depression in the 1930s. Today the park serves as a hub for many recreational activities and the hike and bike trail around Lady Bird Lake, both of which run next to the park. The large size of the park makes it a capable venue for large-scale events such as the Austin City Limits Music Festival and the Zilker Park Kite Festival. The park was listed in the National Register of Historic Places in 1997.
