Sometimes we go out to ride the trails so that you don't have to - and this is a definite case. The trail is located about 30 minutes from downtown Austin and is not worth the drive. This is primarily because it is almost all jeep trails and they allow horseback riding. This tears up the trail and makes it difficult to ride.
I did a scant 12 miles and it was mostly unsatisfying. If you happen to be staying at the Hyatt Hill Country Resort and you have a bike with you then it is probably worth the time if you want to get away from the family, but I would not want to make this a destination

Directions: Take highway 183 south from Austin, past Route 71 East, just past the Berdoll's pecan store and you'll see the entrance right after the Hyatt Hill Country Resort.
