Hippie Hollow Park (originally known as McGregor County Park) is a park located on the shore of Lake Travis in northwest Austin. It is the only legally recognized clothing-optional public park in the State of Texas.
Though the land is owned by the Lower Colorado River Authority, it is leased to Travis County, whose Parks Department has administered the park since 1985. Sometimes erroneously labeled as a beach, the park actually sits on a somewhat steep slope above Lake Travis with limestone steps that can be quite rugged in some spots. Depending on the water level of the lake, access to the water may require some rock climbing. The park has an area of 119 acres (41 hectares) and receives approximately 153,000 visitors annually.
