The Itinerary
As you descend 180 feet below ground level, you’ll traverse close to three-quarters of a mile of winding pathways. While the walk isn’t overly strenuous, it involves stairs and uneven surfaces, so wearing comfortable, good-traction shoes is vital. Expect to encounter a temperature around 70°F with near 100% humidity, creating a moist, cool environment that helps formations grow but can also make the pathways slick.
Visual Highlights
Once inside, you’ll be greeted with spectacular formations—some of which have grown over thousands of years. Reviewers frequently mention the stunning shapes of stalagmites and columns that seem almost sculpted by an artist. One tourist described the formations as “so beautiful,” emphasizing how each area offered a different visual experience.
Guides carefully point out features like flowstones, soda straws, chandeliers, and other formations still actively growing, which lends a sense of living history to the cavern. One reviewer noted that the lighting adds a modern, almost cinematic effect, making the natural beauty easier to appreciate.
The Guides and Educational Content
The guides are a highlight for many visitors—they’re praised for their knowledge, friendliness, and engaging storytelling. One reviewer mentioned a guide named Matt, describing him as an “amazing” storyteller who made the experience memorable. Another appreciated guides who took time to answer questions thoroughly, sharing insights about the formation process and the ecosystem within the caverns.
However, a few guests felt that some guides could speak a bit slower for international visitors, but overall, the guides’ expertise shines through. The live narration makes the experience feel personal and educational, turning a walk through caves into a journey through Earth’s natural timeline.

Ticketing and Timing
The $36 price covers both your entrance and guided tour—offering good value for the experience. Tours are scheduled in staggered times, so it’s best to check availability beforehand to secure your preferred slot. The activity generally lasts about an hour.
Walking and Accessibility
It’s important to note that strollers are not recommended due to stairs and uneven paths. The walk is approximately 3/4 mile, with a descent of 180 feet into the caverns. The temperature remains steady at around 70°F, but the high humidity (99%) can make it feel warm and sticky, especially on a hot Texas day.
What to Bring
Comfortable shoes with good traction are a must. Because of the wet and sometimes slippery pathways, flip-flops or sandals are not ideal. Bring a camera—pictures are encouraged, and the formations look especially stunning under the cavern’s LED lighting. No food or drinks are included or allowed inside, so plan accordingly.
Group Size and Tour Atmosphere
Many reviews highlight the small group environment, which allows for better interaction with guides and a less crowded experience. That said, some reviews mentioned groups can get a bit noisy, which might detract from the ambiance for some.

Many reviewers also appreciate the educational aspect—learning about how formations grow and the ecosystem within the caves. The guides’ enthusiasm and expertise are often praised, with one guest describing a tour guide as “unflappable” and “professional”.
Dealing with the Environment
Several visitors noted that the temperature and humidity can make the experience physically intense—particularly on warmer days—so visiting on a cooler day or bringing a light jacket might be wise.
