Probably the signature trail in Austin. Ten miles of trail on each side of the lake (Colorado River). Very nice, winding trail with views of the river, lovely green and shade in spots…and some 30,000 runners a day! We start at Congress St. Bridge, which is close to downtown. Some interesting pedestrian bridges, the Barton Pool, and numerous lovely parks and greenways. A significant improvement, as of June 2014, is the boardwalk on the east end of the Longhorn Dam. There are options to make the run shorter by turning around at one of the bridges, or to lengthen it at Ziker Memorial Park by running along the Barton Creek Trail. Water and bathrooms.
