Devil's Sinkhole State Natural Area is a natural bat habitat near the city of Rocksprings in Edwards County in the U.S. state of Texas. Home to the Mexican free-tailed bat, access to the area is available only through advance reservations.


The Devil's Sinkhole is a vertical natural bat habitat. The 40-by-60-foot (12.2 m × 18.3 m) opening drops down to reveal a cavern some 400 feet (122 m) below. The cavern was first discovered by local residents in 1876. H. S. Barber carved his name inside the cave in 1889.[1] The area was transferred to the state of Texas in 1985, and open to the public in 1992.[2] Carved by water erosion, the cavern is home to several million Mexican free-tailed bats that emerge at sunset during April through October.[3]

In 1968, the Devil's Sinkhole was designated as a National Natural Landmark by the National Park Service.[4]

Facilities, admission[edit]

Evening bat flight tours are offered in summer only. Guided nature hikes also are available.[2]

Facilities include a wheelchair-accessible viewing platform and picnic areas.[2] Access is restricted to advance tour arrangements. Tours are conducted by the Devil's Sinkhole Society, a local volunteer group that works in conjunction of Texas Parks and Wildlife Department and Bat Conservation International to facilitate visitor education and tours.[5]
