Located within the city limits of San Antonio, Government Canyon State Natural Area (GCSNA) is one of the largest karst preserves in the country and protects an oasis of nature. In the early 1850s, government surveyors established a military supply route through this area. The locals’ nickname for the project—the “government road” that was being built through the “government’s canyon”—stuck! Today, visitors can explore this story and many more through hiking, biking, birding, trail running, picnicking, and attending regularly-scheduled programs.
