South Llano River State Park is on a spring-fed, slow-moving river near Junction, about two hours from San Antonio. Most visitors come to swim, tube and paddle its two miles of river frontage. It's also an International Dark Sky Park, and one of the largest turkey roosts in Central Texas. From October through March, the day-use area is open only from 10 a.m. to 3 p.m. to protect the roosting turkeys.
