The Inner Space Cavern in Georgetown, TX is the perfect day trip when you are looking for an adventure!
The cavern is open year-round, but when you visit in the summer you can get a little reprieve from the sweltering Texas heat. The temperature inside the cave is a moderate 72 degrees year-round.
The cavern was discovered in 1963 while construction workers were drilling to determine if they could build a highway.
One of the workers volunteered to be lowered down in the hole to see what was down there. Then after just 3 years of excavating it was opened to the public.

They have a playground, mining area, fossil displays that were found in the cave, and animals to entertain you while waiting for your tour time.
Once inside, the tour guide tells you about all the formation and fascinating stories of the cave’s discovery. Some of the beautiful formations you will see are the Soda Straw Balcony and The Flowing Stone of Time – just so cool!
About halfway through the tour, the guide will turn off the lights in the cave. It’s so cool to experience total darkness like no other, yet it is also a little nerve-wracking. I was a bit relieved once he turned the lights back on!
Inner Space Cavern is open year-round and offers 3 types of tours. You can choose the length and the type of adventure you are wanting.
