The Stephenson Preserve is part of the City Of Austin's Central and Eastern Preserves group. This park offers a lot of lesurely hiking and great nature views!
From MoPac Expressway in west Austin, turn onto William Cannon and head east. Turn left onto Brodie Lane and head south. Turn left at the first street, which is Paisano Trail. This narrow road will turn a couple of times to the right and left until it parallels LongView Park. Look for parking on the left. The Stephenson Preserve trail begins in LongView.
