Possum Kingdom State Park, west of Mineral Wells in Palo Pinto County, is 1528.7 acres adjacent to Possum Kingdom Lake. Some of the rock facilities at the park were constructed by the Civilian Conservation Corps (CCC) in the early 1940s. The area was acquired by deed from the Brazos River Authority in 1940 and was opened to the public in 1950.

This park is located in the rugged canyon country of the Palo Pinto Mountains and Brazos River Valley, and is adjacent to Lake Possum Kingdom, 20,000 acres of the clearest, bluest water in the southwest. Numerous white-tailed deer make their home in the park. The Possum Kingdom Longhorns are on sabbatical roaming the rolling plains and woodlands of San Angelo State park while their home range is being rested and restored for their return in a few years.

The park has a privately operated store and marina. The store carries groceries, bait, tackle, miscellaneous camping supplies, firewood, and a large assortment of T-shirts, and souvenirs. The marina offers both motorized and non-motorized boat rental, covered slip rental, and a gas dock. Reservations are strongly recommended for motorized boat and slip rentals. Store hours vary with the seasons. Please call 940/549-5612 for boat or slip reservations.
