The Pedernales River Nature Park is a day-use property open to the public for fishing and picnicking. The 222-acre tract of riverfront land, known locally as the old Rainbow Ranch Trout Farm, is centrally located and easily accessible to all of Blanco County. The park offers picnic tables shaded by oak trees and lots of open space. A shaded riverbank provides a nice spot for anglers, bird lovers and anyone wanting a quiet place to relax. Swimming is not allowed.
