Evening hike with a HCO group. We started right across the street from the Rowing Dock, where there is what is clearly an official trailhead that is nonetheless quite overgrown and is nearly impossible to see until you're right on top of it. Backtracked a couple of times after going down side trails that petered out. The overlook of downtown Austin was very nice though, particularly at sunset. Some parts of the trail were pretty well marked (including a map that suddenly appeared in the middle of the hike), but it was hit and miss between that and the overgrown portions.
