A registered National Natural Landmark since 1985, the Devil's Sinkhole plunges a remarkable 400 feet into the earth and has a 40'x60' opening, making it the largest single-chambered cavern in the state of Texas. Significant archeological evidence found in the area indicates that the sinkhole was once a sacred burial site for Native Americans, and in summer months millions of Mexican Free-Tailed bats call the cavern home and emerge en masse each night as dusk arrives.
Join the Devil's Sinkhole Society this Obscura Day for a nature tour and guided hike of this truly impressive cavern as we delve into the fascinating history and unique ecology of the area.
