Big Spring State Park, State park on Scenic Mountain in Big Spring, Texas.

Big Spring State Park covers 381.99 acres on Scenic Mountain, a limestone hill rising to 844 metres above sea level in Howard County. A three-mile loop drive circles the mountain, its retaining walls built of large limestone blocks, some weighing up to two tons, laid without mortar. Trees include honey mesquite, Havard oak and redberry juniper, with prickly pear cactus most abundant.

The city of Big Spring deeded 381.99 acres on Scenic Mountain to the state in 1934 and 1935, and the park opened in 1936. Civilian Conservation Corps crews then built the headquarters, pavilion, lodging, pump house and restrooms from limestone quarried on-site. They also laid a three-mile loop drive with mortarless retaining walls of blocks weighing up to two tons.

The spring that gave the park its name was first recorded on October 3, 1849, in the journal of Captain R. B. Marcy of the U.S. Cavalry, returning to Fort Smith, Arkansas, from Santa Fe. The original natural spring was later replaced by an artificial one. Carvings dated around 1917 show that cattle drivers and migrants also stopped here.

Facilities sit near the park entrance on Scenic Mountain, not at the summit: a lighted group pavilion seating up to 50, restrooms without showers, and a Texas State Park store. A seasonal interpretive center displays Native American artifacts and local fossils. A three-mile loop drive circles the mountain, with limestone retaining walls along it.

During summer months the Big Spring Film Society shows movies under the stars at the mountain summit. These outdoor screenings offer an unusual experience of film and nature in the same location.
