Description: Government Canyon State Natural Area is an approximately 8,624-acre area in Bexar County, just outside San Antonio. The State Natural Area was purchased by Texas Parks and Wildlife Department in 1993, in cooperation with Edwards Aquifer Authority (formerly Edwards Underground Water District), San Antonio Water System, the Trust for Public Land and the federal government Land and Water Conservation Fund. The park opened to the public on October 15th, 2005.

Trees such as Mountain Laurel, Ashe Juniper, Mesquite and Live Oak abound, as well as Mexican Buckeye, Lindheimer’s Silk-Tassel and Escarpment Black Cherry. Steep slopes provide scenic overlooks of the surrounding Bexar County and glimpses of San Antonio. Rare birds such as the Golden-cheeked Warbler can be found. Geologically, the Natural Area lies on the Balcones Escarpment, an area of deeply entrenched canyons that defines the eastern boundary of the Edwards Plateau. Approximately 88% of the Natural Area overlays the Edwards Aquifer recharge zone. The remaining acreage overlies the transition zone for water recharge.

History:The canyon was on the "Joe Johnston" Road from San Antonio to Bandera which was blazed by the military at Ft. Sam Houston in the 1850s. The canyon is a part of the rich ranching history of Texas.
