COBB CAVERNS. Cobb Caverns is on the Cobb Ranch halfway between Florence and Georgetown in northwestern Williamson County. Although the cave had been known for several decades, it was not opened to the public until June 1962. A commercial trail follows a high-ceilinged, linear passage for 1,000 feet, past flowstone-coated walls, "totem poles," and boxwork. An additional 1,000 feet of passage is not open to tourists. Indian artifacts have been found in old campgrounds at nearby Cobbs Springs.
