The Little Walnut Creek Greenbelt encompasses over 200 acres of undeveloped land near the intersection of 51st St. and U.S. 183. The greenbelt consists of vistas, creeks, natural features, and wildlife in the heart of East Austin. Over four miles of trails stretch across the greenbelt, but there is potential for much more. Friends of Little Walnut Creek is a group of neighbors and members of the East Austin community whose goal is to promote the development of the Little Walnut Creek Greenbelt.
