I parked at the top of the side trail (Fern Hollow?) and hiked down to junction at Panther Hollow and then down to the pond and back up along the utility trail to the junction in Panther Hollow and then north up to the trailhead at the north end then south along River Place Blvd back to the Jeep so that is how I got my miles without any retracing of steps.
This is THE BEST neighborhood greenbelt trail I have seen in Austin. Such terrain, such scenery! It was neat to see the pools of water along sections of the trail, no doubt caused by run off from the golf course above the hollow. This will be an outstanding hike after we finally get some real rain here in Central Texas.
