My first trail from the Texas Hiking site - I parked at Cedar Breaks Park, and had no trouble finding the trailhead. It was a 6-8 foot wide concrete sidewalk through a wooded, shady area. I crossed over the dam road on the walk. I didn't see any other people, and it was very peaceful. It was almost entirely level - a very easy walk for the part I was on.
