First opened to the public in October, 2005, Government Canyon State Natural Area (GCSNA) preserves 12,244 acres (49.5 km2; 19.1 sq mi) of rugged hills and canyons typical of the Texas Hill Country. It is designated a Natural Area, rather than a State Park, and therefore the primary focus is maintenance and protection of the property's natural state. Accordingly, access and recreational activities may be restricted if the Texas Parks & Wildlife Department (TPWD) deems such action necessary to protect the environment.
