Devil's Sinkhole State Natural Area

Things to Do

The main attraction is the Devil's Sinkhole itself. It is a vertical cavern with an opening measuring approximately 40x60 feet, and a vertical drop to the main cavern of about 140 feet. The main cavern is circular and reaches a total depth of 350-400 feet.

There is minimal development in the Natural Area, including picnic sites, a chemical toilet, and some trail development. A new wheelchair accessible viewing platform is now available and allows visitors to look into the Sinkhole. Visitors are not allowed to enter the Sinkhole.

Ranger Programs

Access to the park can be obtained only by contacting Devil's Sinkhole Society (830) 683-BATS (2287) to prearrange a tour. Tours are by reservation only. Check the calendar for upcoming events. Special day tours can be arranged with a minimum of three days notice. Reservations are required.

Evening Bat Flight tours are being offered from Wednesdays through Sundays, through the end of October. Labor Day (Monday) will also be available for this popular tour. Adults $12, Seniors $10, Children 4 to 11 $6, Children under 4 are free

With its bat population surging strongly this summer, the Natural Area is currently offering Morning Bat Return tours on the Saturdays of September 8, 15, 29, and October 13. The Morning Bat Return tours begin just before dawn at the Rocksprings Visitors Center (830) 683-2287, on the Rocksprings town square, and proceed by "Batbus", or car convoy, to the famous cave, to witness the 3.8 million bats slicing through the air at high speed as the bat roost completes its nightly sortie. Tours are conducted by the Devil’s Sinkhole Society and reservations are necessary. Tickets for the morning tour are $20 and $10 for children eleven and younger.

The Devil's Sinkhole Society also offers nature walks, birding outings, day tours to the sinkhole overlook, and motorcycle tours. These tours need to be arranged in advance but are usually available throughout the year, except when the site is closed during hunting season. All tours begin at the Rocksprings Visitors Center on the Rocksprings town square.

The Devil’s Sinkhole State Natural Area operates in partnership with Kickapoo Cavern State Park, which offers picnic sites, camping, hiking, mountain biking, bird watching, cave tours, and also has a popular bat cave with evening bat flight viewing, during the season.
