Time Out says
Sandy Creek Park, located on the northern portion of Lake Travis, is one of the quieter coves in the area. Visitors can swim, hike, camp and fish across its scenic 92 acres. Birding enthusiasts also have the chance to spot the rare golden-cheeked warbler here. For those who are interested in camping overnight, no reservations are required but spots are available on a first-come, first-served basis. There’s drinking water, restrooms and barbecue pits available, just don’t forget to bring your own firewood.
