Pedernales Falls State Park Camping
Camping here puts you inside one of the darkest skies within an hour of Austin, and the park runs regular night-sky programs to take advantage of it. The main campground has water-and-electric sites in oak and juniper woods, plus walk-in primitive sites and a backpacking area for families ready to carry gear a couple of miles. Days go to the falls overlook, the swimming beach downstream at Trammel Crossing, and the bird blind. The falls themselves are for looking, not swimming, and the river can rise fast after upstream rain.
