Forty-acre Blunn Creek Nature Preserve, across the street from St. Edward’s University, remains wild and natural. The looped trails are well marked and maintained, although portions are rocky and steep. Just blocks away from nearby Blunn Creek Greenbelt, Blunn Creek Preserve feels like another world altogether. The park is larger, more rugged, less visited and offers a bit more of a true hiking experience, all the while still surrounded by South Austin.
