Devils Sinkhole entranceNative Americans knew about Devil's Sinkhole long before Anglo settlers discovered it in 1867. It is now a registered National Natural Landmark.

Devil's Sinkhole State Natural Area was once part of the Whitworth Ranch. It is 1,859.7 acres located about six miles northeast of Rocksprings in Edwards County.

The state acquired the property in 1985 and opened it for limited access in 1992.
