Longhorn Cavern State Park: Walking on the Underground River

Longhorn Cavern - Walking on the Underground River - Burnet, TX - Two Worlds Treasures



Every time I saw pictures of Longhorn Cavern, I felt like I would be walking on the underground river with imaginary water surrounding me when I go there. The cave looks beautifully sculpted, as if flowing smoothly to the mysterious end.

After a long year of waiting, we finally made it to Longhorn Cavern SP on Labor Day. We arrived slightly after the 10.30 a.m. tour left, so we used our time to visit the original administration building built by the Civilian Conversation Corps Company in 1937 and did some shopping at the souvenir shop.

Our cave Walking Tour began at 11.00 a.m., led by a retired geologist, Mr. Al ‘Jarreau’. I looked around and realized we were a big group. There were at least 20 people in the group. Hmm… Mr. Jarreau said, if we came last week, there were only 4 people. Lucky them! But we came on Labor Day, so I couldn’t expect small number of tourists there.

Before we walked to the cave entrance, he warned us that we would walk through a passage with height less than 5 feet called Lumbago Alley, where we had to bent down and walked for a few yards. So, people with back problem must think again before we continued the tour. Well, seems that nobody had a problem.

My feeling was right. Longhorn Cavern called a flow cave, because over many years running water that penetrated the limestone bedrock formed the cave. That’s why it’s much more sculpted and has a very long fairly level.

Welcome to the cave.


Our first stop was not far from the entrance where we saw one of the cave’s resident: Eastern Pipistrelle, the tri-color bat. They are very small, with size just a bit bigger than an adult thumb. We’re not allowed to take picture with flashlight since it would wake them up from their sleep. They looked cute though. “Mommy, can I have a bat for a pet?” whispered my son. Oh, no. Bats are not pets.

Then we continued and stopped at the Crystal City, where glittering calcite crystals line both sides of the wall. There are two passages that we could walk through to see these glittering calcite.

Next, we met Rocky Rockweiller, also known as the Queen’s Watchdog. He is the cave’s pet dog. Geologist estimate Rocky is 2 million years old and is naturally formed by erosion. The CCC guys found him further inside but put him on this place. Back in the 1950s, people who visited the cave used to sit on him. But today it’s prohibited.

In addition to that, we saw three other main rooms in this cave: the Indian Council Room, the Underground Ballroom, and the Hall of Gems which is easily becoming visitors’ favorite with wall to wall glittering calcite, with size as big as an adult’s head.

This 90 minutes walking tour took us to 135 feet deep into the earth. I have a minor claustrophobia, but it didn’t bother me at all. The air was moving, lights illuminating different points of interesting rock formation, making inside the cave is not totally dark.



At one point deep in the cave, the tour guide turned off the light to give us the feeling of total dark when the CCC guys walked into this cave. Then he turned on his flashlight and pointed to a wall to give us idea how “bright” was the cave when they worked with only lantern as the source of light, digging and removing more than 2.5 million cubic yards of debris and guano from the cave. But don’t worry. The guide told us what he’s going to do, so the ones whose afraid of the dark could prepare themselves.

With the temperature inside at 68 degrees year-round, this cave is a great retreat from the Texas summer heat and winter cold. But you need to watch your step because lots of slippery spots.


Longhorn Cavern: History and Legend


  • Comanche tribes used to conduct meetings at the Indian Council Room and trapped horses in the cavern.
  • Confederate soldiers used the endless supply of guano to make gun powder and stored them here.
  • During Prohibition in 1920s, the cavern turned to a night club.
  • During the Great Depression, President Roosevelt created a program called the Civilian Conservation Corps. Thanks to the men who cleared out the cavern with shovels, picks, and wheelbarrows, we now can visit the cavern and enjoy it in comfort.
  • The outlaws sometimes lived here and legend has it that Sam Bass, the Texas infamous outlaw, hid $2 million in the cave. The money has yet to be discovered.

As I mentioned above, we visited the original administration building built by the CCC in1937, located right next to the new one. We were just impressed with their work. Here are pictures from the historic building.

As usual, we always reminded our son about what is CCC, created by F.D. Roosevelt during the Great Depression. I think it’s important for him to know that part of the history of the country.

The CCC men also built the picnic area, the Officers Quarters, and the Watch Tower.

We enjoyed our visit there much, walking on the underground river. My son wishes to do the Wild Cave Tour once he’s 11 and I wish to do the Photography Tour because I didn’t make good pictures in this trip, while my husband would like to do the tour one more time with only 5 people the most in the group. So, it’s more personal and you can actually listen to all information clearly, stay longer at every point, and have a deeper Q & A with the tour guide.

    Wow that looks like such a fun place to visit. I can’t believe the dog was naturally formed! Looks like a statue. My kids would want a pet bat too- shivers lol sounds like you all had a great time. I’m going to put this on my travel list ❤️

    1. Umiko Buhl says:

      We did have a great time! Looking forward for the personal tour.

  3. Marta says:

    Such an interesting history! I think that I might be a bit claustrophobic if there were too many people on the tour.

    1. Umiko Buhl says:

      I personally think there were too many people in the tour. I thought they would limit the number.

  4. Daniela says:

    I haven’t been to a cave for ages. The hall of gems looks stunning. And you had an 86-years old tour guide? Wow, hope I’ll still be that active once I reach that age (if I do). The park also looks great. A bit like parts of a European fortress from the Middle Ages.

      Don’t we all wish to be as active when we reach the tour guide’s age?

  5. Laura says:

    What an informative post! My mother grew up in Texas and her family still lives there. This might just have to go on our next Texas road trip itinerary, as I had never heard of this park before now.

    1. Umiko Buhl says:

      Cool! What part of Texas? Yeah, do stop at Longhorn Cavern. It’s part or close to Hill Country. Lots of point of interests there.

  6. shannon says:

    1. Umiko Buhl says:

      I really wanted to touch that little bat, but I know Mr. Jarreau would kick me from the tour. 🙂

  7. Great info and pictures 😊 👍

      Thank you!

  8. Victoria says:

    After a long year of waiting? Was that because you had planned the trip for an entire year? How amazing. I do that sometimes too. Thanks for the cost info.

      We wanted to visit Longhorn Cavern last year during Spring Break but it was late already. Then there’s always something at the weekend we thought about going there. Finally, we made it there last Labor Day.

  9. Meagan says:

    That dog “statue” is so cool! And the rest of the cave looks stunning. We’ve been to Luray, but this is totally different. Thanks for sharing!

    1. Umiko Buhl says:

      Yes, the dog statue is everyone’s darling. Where is Luray?

    1. Umiko Buhl says:

      Well, thank you! We enjoyed the cavern and I wish to take the photography tour in the future.

  13. Lisa Guerrero says:

    My brother is a tour guide for Longhorn Cavern so I’ve been in there many times. Your article about the cavern is the best I have seen written, ever. You really captured what it’s like when you are down there, the pictures are great, and I love how you included the history of before the CCC and what they did to make the cave passable for all of us to enjoy today. P.S. My brother is the guide for the photography tours. I’m STILL waiting to do that one. And you should ALL go on the Wild Cave Tour! It’s a little cramped and I came out dirty but unscathed. Not a single nightmare!

    1. Umiko Buhl says:

      Wow and thank you! Does your brother give any input for taking pictures during the tour? Because I’m still struggling and I know I can take better pictures. And yes, we will definitely go back again for the Wild Cave Tour! I hope my minor claustrophobia won’t be a problem.

  14. What a cool place to explore, I can see why you were excited about going. Interesting that they used it as a nightclub at one time…
