The Texas Hill Country is a geographic region of Central and South Texas, forming the southeast part of the Edwards Plateau. Given its location, climate, terrain, and vegetation, the Hill Country can be considered the border between the American Southeast and Southwest. The region represents the very remote rural countryside of Central Texas, but also is home to growing suburban neighborhoods and affluent retirement communities.
The Natural Bridge Caverns are the largest commercial caverns in the US state of Texas. The name is derived from the 60-foot (18 m) natural limestone slab bridge that spans the amphitheater setting of the cavern's entrance. The span was left suspended when a sinkhole collapsed below it.
The Edwards Plateau is a geographic region forming the crossroads of Central, South and West Texas, United States. It is named in honor of Haden Edwards. It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to the west. San Angelo, Austin, San Antonio and Del Rio roughly outline the area. The plateau, especially its southeast portion, is also known as the Texas Hill Country.

Longhorn Cavern State Park is a state park located in Burnet County, Texas, United States. The Texas Parks and Wildlife Department is administrator of the facility. The land for Longhorn Cavern State Park was acquired between 1932 and 1937 from private owners. It was dedicated as a state park in 1932 and in 1938 was opened to the public.

The Parque Nacional de las Cavernas del Río Camuy is a cave system in Puerto Rico. It is located between the municipalities of Camuy, Hatillo, and Lares in northwestern Puerto Rico, but the main entrance to the park is located in Quebrada, Camuy. The caverns are part of a large network of natural limestone caves and underground waterways carved out by the third-largest underground river in the world, the Río Camuy. The cave system was "discovered" in 1958 and was first documented in the 1973 book Discovery at the Río Camuy (ISBN 0-517-50594-0) by Russell and Jeanne Gurnee, but there is archaeological evidence that these caves were explored hundreds of years ago by the Taíno Indians, Puerto Rico's first inhabitants. Over 10 miles of caverns, 220 caves and 17 entrances to the Camuy cave system have been mapped so far. This, however, is only a fraction of the entire system which many experts believe still holds another 800 caves. Only a small part of the complex is open to the public. The 268-acre park built around the cave system features tours of some of the caves and sinkholes, and is one of the most popular natural attractions in Puerto Rico. After restorations necessitated by Hurricane Maria, a destructive storm that struck Puerto Rico in 2017, the park re-opened on March 24, 2021. It then closed again from September, 2022 until February, 2023 due to Hurricane Fiona.
Balcones Canyonlands is a national wildlife refuge located in the Texas Hill Country to the northwest of Lago Vista, Texas. The refuge was formed in 1992 to conserve habitat for two endangered songbirds, the golden-cheeked warbler and the black-capped vireo, and to preserve Texas Hill Country habitat for numerous other wildlife species. The refuge augments a similarly named preserve in Austin called the Balcones Canyonlands Preserve.
First opened to the public in October, 2005, Government Canyon State Natural Area (GCSNA) preserves 12,244 acres of rugged hills and canyons typical of the Texas Hill Country. It is designated a Natural Area, rather than a State Park, and therefore the primary focus is maintenance and protection of the property's natural state. Accordingly, access and recreational activities may be restricted if the Texas Parks & Wildlife Department (TPWD) deems such action necessary to protect the environment.

It has been commercially operated as a show cave and open for public tours since 1932. Informal tours were run as far back as 1875, when Dr. Benjamin Hester owned the cave property.
