CMSCHUT - Just from the little research I did, there are several states that have public bat caves - TX, FL, and MO are ones that I noticed right off the "bat"!
I suugest that you google it if you want to go in this direction. I respectfully submit that the jewels are in the the forest - I'm looking at plant life, trees, etc.
I found a great site about a TX bat cave - here's an edited version. You never know, since no one that I've heard of has found anything, you never know when one word or image could break this thing wide open:

Kickapoo Cavern State Park and Devils Sinkhole State Natural Area
BAT FLIGHTS, CAVE TOURS AWAIT AT KICKAPOO CAVERN, DEVIL?S SINKHOLE
....Stuart Bat Cave ? a ?remote 6,368-acre park straddling the Kinney-Edwards county line. A full-grown porcupine appears on the rocky hillside just above the lip cave opening, more interested in chomping on the foliage of an overhanging shrub than in the presence of the human intruder less than 30 feet away.
? 310-foot collapsed limestone pit that is the heart of an 1,859-acre state natural area. It reigns as the largest single-chamber and third deepest cavern in Texas.
Like Kickapoo Cavern, the mostly undeveloped Devil?s Sinkhole SNA is open to the public by prior arrangement only. The non-profit Devil?s Sinkhole Society takes reservations (830-683-BATS) for bat flight observations and afternoon sinkhole tours. Currently, bat tours take place Wednesday through Sunday nights, and sinkhole tours on weekends only. Tour participants meet at the Visitors Center in Rocksprings for the 20-minute bus ride to Devils? Sinkhole six miles northeast of town.
Thanks to the installation last summer of a wheelchair-accessible viewing platform that extends just beyond the edge of the sinkhole, the public can more readily peer into this amazing registered National Natural Landmark some 70 miles west of Kerrville. Before the platform was constructed, a park visitor seeking a glimpse into the depths of Devil?s Sinkhole would have to lie on his stomach and inch forward to the edge of the 46-foot wide chasm to view the trees, shrubs, ferns and boulders on the floor of the main cavern 140 feet below. A new chemical vault toilet and picnic facilities near the sinkhole have brought additional creature comforts to tour participants. And by this time next year, the two-mile, gravel ranch road leading to the sinkhole will be paved.
Kickapoo tour participants must make advance reservations (830-563-2342) to guarantee admission to the park, whose gates are kept locked to control entry to the state natural area, which contains noteworthy, and in some cases endangered, natural and cultural resources.
Kickapoo Cavern traditionally has restricted public access, too, because of a lack of suitable infrastructure ? water, sewer, electricity and overnight facilities. But Knezek says that is slowly changing. A park road and water-wastewater system were recently constructed. Several miles inside the park gates, there are signs of ongoing development. A new restroom stands just off the road and campsite construction is under way next to the day use picnic area. When completed, the campground will feature 14 sites, some of which will be able to accommodate recreational vehicles.
Motorists heading to Big Bend and folks from as far away as Houston and Dallas find their way to Kickapoo Cavern for ?wild cave tours.? Trained guides lead visitors through the park?s namesake, the largest of 16 caves found in this land of steep limestone hills, extensive canyons and grasslands located roughly 10 miles north of the Balcones Escarpment, an uplift along the Balcones Fault Line. Here over the eons, carbon dioxide-charged water has flowed underground, dissolving limestone structures, creating caves such as Kickapoo Cavern filled with eye-catching cave formations, known as spelothems.
Guided two-hour, flashlight tours take adventurous participants across fields of loose boulders more than 1,000 feet deep into the main rooms of the cavern to view bizarre-looking icicle-like stalagtites, stalagmites and helictites, flowstone and 80-foot twin, crystalline calcite columns ? the largest of their kind in Texas. Here, in this subterranean wonderland of weird formations, trickling water and odd creatures like cave crickets, harvestmen and scorpions, tour participants can marvel at Nature at work ? four million years and counting. Note: Couch potatoes need not apply for this moderately strenuous tour. Reservations are a must.
