Let’s Go Spelunking in Austin (or super nearby)!

Spelunking in Austin

Explore Inner Space Caverns

Explorers of all ages and sizes will be absolutely awed by Georgetown’s Inner Space Cavern. Located 30 minutes north of Austin, the caverns are open daily and offer not one, but three different tours through their many underground mazes. They are set up so you can design-your-own adventure based on the age and skill level of your spelunkers.

The caverns were discovered in 1963 while the Texas Highway Department was researching whether the area could support a large highway overpass. Instead, the drillers found a 26-foot drop. By November of the same year, 7,000 feet of the caves had been surveyed. The first explorers found passages ranging from very tight crawl spaces to large cathedral-type rooms and halls. Three years later, they were opened to the public. 

Because the caves are – well, caves, and located underground – exploring them is a great way to be outside with a much-needed reprieve from the hot summer sun. That said, don’t expect it to be cool inside. According to the website, it’s usually 72 degrees in the cavern, but with regular 98% humidity, it feels closer to 80 degrees inside. Open seven days a week, the cavern tours are not free, but we think it’s well worth the price to go spelunking in Austin!

Know before you go:

The caves are open, but due to COVID-19, masks must be worn by all spelunkers ages 10 and up. Physical distancing is enforced and tour capacity is limited (see website for availability and to purchase tickets in advance). Intense cleaning protocols are exercised, and staff members experience temperature checks upon arrival.

As always in these fluid times, it’s best to visit the website or call for the latest updates before driving out.

Prices vary by day (it’s slightly cheaper to visit Monday through Thursday) as well as the tour selection. The hour-long Adventure Tour is cheapest ($14.95-$21.95) and by far the easiest to traverse. A guide will lead explorers for a mile walk over a paved, lit trail passing through large rooms and formations while sharing the cavern’s history. All ages are welcome on the Adventure Tour.

The Hidden Passages Tour costs $5 more per ticket and lasts a little longer at approximately an hour and a half. The guide provides guests with flashlights to better explore the more delicate cave formations. This tour takes you past some of the site’s undeveloped trail through a newly-opened section of the caverns. Due to a more rugged terrain, this trail is not open to kids under seven, and guides recommend that guests with physical limitations or claustrophobia sit this one out. 

For a much heftier fee, the Wild Cave Tour is $100 per person and takes guests – 13 and up – on a three to four-hour adventure through deep underground passages. Expect hiking, crawling, climbing, and squeezing through tight spots. Previous experience is not required, but be warned this tour is described as physically demanding and a signed waiver is required.

We know exploring takes a lot out of little adventures, so hit the refuel (and refresh) button with some much-needed Tex-Mex. El Monumento, also in Georgetown, is a ten-minute drive from the cavern and offers a shaded patio that’s open to socially distant customers at 50% capacity (check online or call to be sure). Or, if you prefer the pick-up and go option, that’s available too. 

Cheese lovers will swoon over the queso, a Los Nino’s menu is available for the 12 and under crowd (chicken fingers and all), while the 21 and up guests can enjoy a refreshing house margarita.

At Berry Springs, you’ll also find a 2.5-mile hike (or biking!) trail as well as a pond that’s great for fishing but not open to swimmers. Water fountains have been turned off until further notice, so make sure to bring water.
