Longhorn Cavern State Park is one of the most unique underground experiences you can share with kids in Texas. The guided walking tour covers about a mile through a massive cave system carved by an ancient underground river, and unlike most cave tours, the path is mostly flat, dry, and well-lit - making it manageable for kids as young as 4.

The cave stays a constant 68 degrees year-round, which makes it a perfect escape from Texas summer heat or a cozy winter outing. Cathedral-sized rooms open up along the route, and your guide will point out fascinating geological formations along with stories about the cave’s wild history - it served as a Confederate gunpowder factory, a Prohibition-era speakeasy, and a hideout for Sam Bass’s gang.

What kids love most: The sheer scale of the rooms is what gets kids excited. They’ll crane their necks at formations that took millions of years to develop, and the echo chambers are always a hit. Older kids who love geology or history will be completely absorbed by the guide’s stories.

Tour details and tickets: The standard guided tour takes about 90 minutes and costs $18.50 for adults, $11 for kids ages 4-11, and is free for children under 4. Tours run on a set schedule - check the website for current times and consider booking ahead on weekends and holidays when tours fill up. A wild cave tour is available for adventurous older kids (age 10+) who want to crawl through undeveloped passages with headlamps.

Above ground: Don’t skip the hilltop area. The CCC-built stone structures from the 1930s are impressive in their own right, and the panoramic Hill Country views from the observation deck are worth the drive alone. There’s a small picnic area near the parking lot that’s great for a post-tour lunch.

Nearby adventures: Longhorn Cavern is just 15 minutes from Inks Lake State Park, making it easy to combine a morning cave tour with an afternoon of swimming at Devil’s Waterhole. The town of Burnet has family-friendly restaurants for refueling between stops.
