This is a great option just outside of Austin. The trails are different from much of the hill country trails with taller pine trees and more granite instead of limestone. Because this trail is made for horses, it is wide and less technical. This is great for those looking for a beginner friendly course. It is well marked as well, so with this above map you should be set to run on your own.
