11 Top-Rated Caverns in Texas

As part of an extended trip through Texas, Author Brad Lane visited many of the best caverns in Texas.

Everything's bigger in Texas, including the state's collection of caverns. Caves in Texas are most concentrated in a specific region known as the Edwards Plateau. Located west of San Antonio and Austin, the Edwards Plateau includes much of the beautiful Texas Hill Country. It's the unique limestone bedrock of the region that enables beautiful caves to erode and grow over thousands of years.

These caverns near San Antonio and Austin are abundant, but only a few are accessible to the public. The best way to safely explore underground is by visiting a commercial "show cave" that offers a guided tour. Visiting a Texas show cave does not involve crawling in the dark (unless you opt for a Wild Cave Tour). All of Texas show caves include lighted passageways and gravel walkways.

Caverns of Sonora, Cave Without a Name, and Inner Space Cavern are just a few of these accessible show caves. The biggest challenge of most cave tours is descending underground via stairs or steep walkways. All caverns in Texas retain a comfortable climate (approximately 70 degrees) throughout the year, making cave exploration a great thing to do in winter. Visitors will want to dress appropriately, including proper footwear with good traction.

Start your underground adventure by reading our list of the best caverns in Texas.

1. Natural Bridge Caverns

One of the most fantastic caverns in Texas is a 30-minute drive from the attractions of San Antonio. Natural Bridge Caverns is equally close to New Braunfels in the Texas Hill Country.

College students discovered Natural Bridge Caverns in 1960. This family-owned and operated cave system is now one of the most commercially recognized caves in the state. The facility offers several surface attractions, but the real fun is found on an underground tour.

Natural Bridge Caverns offers two main cave tours: the Discovery Tour and Hidden Passages Tour. Both tours follow a knowledgeable guide through lighted cave rooms for approximately 75 minutes. Few other caverns in Texas display the density of cave features seen in Natural Bridge Caverns. Formations include thousands-of-years-old stalactites, stalagmites, and columns.

Tours follow concrete paths and involve steps and steep inclines. Handrails are available for steeper sections of the trail, and comfortable shoes are recommended for the trip. The Discovery and Hidden Passages Tours do not involve crawling or tight passageways. Natural Bridge Caverns does offer a separate Adventure Tour that includes crawling around with headlamps.

Above-ground attractions include dining options, a gift shop, and a 5,000-square-foot maze. Natural Bridge Caverns also recently installed the unique Twisted Trails zip rails and ropes course, which features high-flying fun in a harness. It's recommended to book cavern tours in advance. Natural Bridge Caverns is a popular place for school groups and other large gatherings.

2. Caverns of Sonora

On a private ranch, three hours west of San Antonio, Caverns of Sonora is perhaps the most beautiful show cave in Texas. It's the diverse collection of cave formations that attract speleologists from across the world to this cave in Sutton County. Alongside magnificent columns, soda straws, and draperies, Caverns of Sonora has the best collection of side-winding helictites.

The standard Crystal Palace Tour at Caverns of Sonora is 90 minutes and includes over 360 stairs. The cave is well-lit on this walking tour that takes place over 150 feet below ground. Guided tours are popular with professional cave explorers and interested amateurs alike, and go into detail about the underground world.

3. Cave Without a Name

This untitled cavern features large rooms and many hanging formations, located an hour's drive from both San Antonio and New Braunfels. It was named as such because no title could capture the beauty of the cave system, and Cave Without a Name has been inspiring the public since its mainstream discovery in 1939.

The cave itself has been forming for thousands of years. The massive formations throughout the cave do well to represent this incredible geologic timescale.

The only way to experience this cave in Boerne is through a guided tour. The tour begins by descending 126 concrete steps. From here, you will walk through several large rooms full of stunning cave features. A few of the natural features illuminated on the tour includes stalactites, stalagmites, and soda straws. Lights in the cave make it easy to get around, and the gravel floor helps keep shoes from getting too dirty along the way.

Regular tours of the cave occur throughout the week and last approximately an hour. Reservations are not necessary, but are recommended.

Every month, Cave Without a Name also puts on special concerts in the cave. The natural acoustics of the cave reverberate the musical artist to make for a pretty spectacular show.

Camping is available at an affordable rate at Cave Without a Name.

4. Longhorn Caverns State Park

Longhorn Caverns State Park offers a unique caving experience ninety minutes northwest of Austin. The cave also displays significant cultural depth alongside its rich geologic history.

The Civilian Conservation Corps developed the cavern and encompassing state park in the 1930s. The cavern's history spans further back to the mid-1800s when Anglo settlers first utilized the underground space.

Visitors learn more about the cave and surrounding Backbone Region of the park via a guided tour or surface hiking trails.

5. Inner Space Cavern

The Texas Highway Department discovered this stellar cavern while constructing Interstate 35 in 1963. Public interest quickly grew after the discovery of the cave, and Inner Space Cavern has provided guided tours ever since.

This fantastic cavern, less than 25 miles from Austin, is perhaps best known for the many fossils and animal bones found throughout its corridors. Archaeologists have discovered woolly mammoth bones and remnants of a saber tooth tiger in Inner Space Cavern.

Visitors on the guided Adventure Tour of the cave see the dig sites and examples of these prehistoric remains. The cave system is quite fantastic, even without these ancient artifacts. This 75-minute tour also features several cave formations, including flowstones, soda straws, and cave bacon.

The Adventure Tour is fun for the whole family and features concrete steps and lighted passageways. The Hidden Passages tour at the cave is a bit wilder. It traverses the natural floor of the cave, with flashlights provided. The guides at Inner Space Cavern are some of the most knowledgeable in Texas.

Knowledgeable guides lead these underground tours, traversing concrete pathways illuminated by lights.

Wonder World Cave and Adventure Park is in San Marcos, halfway between Austin and San Antonio. It's the above-ground things to do at Wonder World Cave that also make this cave one of the most popular in Texas.

9. Kickapoo Cavern State Park

This state park near Del Rio is lightly developed and features over 20 known caves. The two largest caves at Kickapoo Cavern State Park are Stuart Bat Cave and the namesake feature, Kickapoo Cavern. The state park prohibits self-exploration of any cavern to protect the delicate habitats. The state park offers guided tours of Kickapoo Cavern on Saturdays, and visitors must reserve their spot ahead of time.

Kickapoo Cavern is less developed than other show caves in Texas. The tours last approximately three hours, and visitors traverse muddy and challenging terrain. Visitors need to bring two sources of light into the cave for their underground visits. While these tours attract a dependable crowd, cave tours are not the defining thing to do at this unique state park in Texas.

The other prominent cave at Kickapoo Caverns, the Stuart Bat Cave, is home to thousands of Mexican free-tailed bats. These flying mammals roost in the cave from the spring through the fall. During this period, the bats erupt from the cave entrance in the evening to put on a spectacular show. Other attractions at the state park include hiking trails, a campground, and a record-setting amount of migratory birds.

10. Devil's Sinkhole State Natural Area

Devil's Sinkhole is a massive vertical cavern that drops straight into the ground, just over two hours west of San Antonio. This enormous hole is over 350 feet deep and is home to a large colony of Mexican free-tailed bats. Over three-million bats call the Devil's Sinkhole home between May and October. This dense concentration of insect-hungry bats offers quite the spectacle to see every evening in the warmer months of the year.

Due to the nature of the cave, no guided tours are available at Devil's Sinkhole Natural Area. Admission to the natural area is also only available through a guided visit. Between May and October, the state natural area offers daily evening tours to watch the explosion of bats coming out of the cave. The state natural area also offers guided nature walks and bird-watching expeditions. Tours meet in the nearby city of Rocksprings.

11. Bracken Cave Preserve

Bracken Cave, a 30-mile drive northwest of San Antonio, offers a different kind of cave experience. This cave isn't for exploring, but instead spectating, as millions of Mexican free-tailed bats emerge from its sinkhole entrance. This dazzling evening ritual occurs between May and September.

Bat Conservation International owns Bracken Cave and the vast surrounding acreage. Membership and reservations are required to see the bats live. Annual memberships are available for a nominal fee. All proceeds go towards the non-profit organization's mission of maintaining crucial bat habitats.

An estimated 15 million bats live in and emerge from Bracken Cave. This makes it one of the largest bat colonies in the world and an almost inconceivable convergence of mammals. And, these flying mammals emerge each evening to consume an equal number of moths and other crop pests. Witnessing this cavern experience is well worth the Texas bucket list.
