We hiked Pace Bend on February 18th and I didn't wear a shirt. You have to love Austin! We did not pass anyone else, but it was a weekday. The hike was supposed to be an up and back, but we ended up making it a loop by going down the road for the last mile to get back to our car. There are a couple of minor hills that give pretty good views, but with Lake Travis low, it is not particularly pretty. These trails are inside the road loop so there is never any water.
