Devil's Sinkhole is a vertical cavern and natural bat habitat near Rocksprings, Texas. Its opening measures approximately 40x60 feet with a 140-foot vertical drop to the main cavern which then reaches a total depth of 350-400 feet. The Sinkhole is the summer home to one to four million Mexican Free-tailed bats which emerge in a swirling mass at sunset during the months of April through October. The Devil’s Sinkhole Society offers Evening Bat Flight tours throughout the summer as well as guided nature hikes. Reservations required.
