Devil's Sinkhole State Natural Area protects a massive vertical cavern that serves as a summer home to millions of Mexican free-tailed bats.
Located near Rocksprings, Devil's Sinkhole State Natural Area is home to one of the largest Mexican free-tailed bat colonies in Texas. The main attraction is the sinkhole itself, a massive cavern that drops 140 feet deep. During the summer months, millions of bats emerge from the sinkhole at dusk to hunt for insects, creating a spectacular natural phenomenon. The surrounding area features rugged Hill Country terrain with oak and juniper trees, providing habitat for diverse wildlife.
Access to Devil's Sinkhole State Natural Area is only by guided tour. Reservations are required, and all tours begin at the Devil's Sinkhole Visitor Center in Rocksprings.
