Government Canyon is real close to West San Antonio, (just outside 1604)
The Area is still being developed. Some facilities and trails are under construction. The Natural Area Headquarters Visitor Center has an exhibit hall and a Texas State Park Store. Other facilities include a group picnic pavilion with 10 picnic sites.Open Friday-Monday and closed Tuesday-Thrusday.
Trails looked great but by mid morning we gave up, it was way too hot.
