Kickapoo Cavern State Park, formerly the Seargeant Ranch, is located approximately 22 miles north of Brackettville, straddling the Kinney/Edwards county line. It is comprised of 6,368.4 acres of the southern Edwards Plateau. It was acquired in December 1986, and was opened to the public on a limited basis in 1991. Daily access to the park became available on June 1, 2010.

Campsites, including full hookups for RVs and a group area, are available. On June 12, 2010, a new 0.75-mile trail was opened and dedicated as the Seargeant Memorial Trail. This trail starts near the campground and traverses creek beds and ridges to reach an overlook with spectacular views of hills and valleys in the park, and then continues on to a location near the original trailhead. A plaque honoring Tommy Seargeant, who sold the land to TPWD and was a strong supporter of developing this park, will soon be erected at the overlook. A shade structure will also be built on this overlook for an enjoyable place to rest and relax in a natural setting.
