Rio Bonito Cabin & RV Park’s location on the North San Gabriel River means it’s an ideal place for your vacation or weekend away. Our location in Liberty Hill allows you to enjoy all the Texas Hill Country has to offer, and there are some spectacular natural wonders right at our doorstep.

Inner Space Cavern is one of these natural attractions and is only eight miles from our property. Even if you’ve visited other caverns, you’re sure to be wowed by this one. Inner Space is one of the most well-preserved caves in Texas, after being hidden for over 10,000 years.

There are three levels of tours, from beginner to advanced, to accommodate a variety of fitness and comfort levels. The Adventure Tour takes you along a well-lit, defined path through the cave and gives you its history. Guests who choose the Hidden Passages tour get a close-up look at cave formations on an undeveloped trail using flashlights. Lastly, the Wild Cave tour takes adventurous guests exploring through undeveloped sections and is more than twice the length of the other tours, but be warned- it’s not for the faint of heart!

In addition to the cave tours, visitors can enjoy a playground, gift shop, and mining area. There is also an exhibit featuring fossils excavated directly from the cave. For more information and to check out the events calendar, head to their website.
