"Emma Long Metropolitan Park, on the shore of Lake Austin, has camping, picnic areas, two boat ramps, a fishing pier, swimming beach, restrooms, and showers. There are restrooms and water fountains in the main park (the entrance booth is another half mile down the road from the trailhead), which has an entrance fee, and dogs must be on leash.
There is no entrance fee at the trailhead, but there are no services, either. This trail is just minutes from the heart of the city, but once you leave the parking area, that is easy to forget. The only sounds you and your dog will hear are the gurgling of Turkey Creek, the breeze through the trees, and birdsong—along with the occasional splashing of a pup who cannot resist a quick swim in the clear water, which flows year-round."
