Caves and Volcanoes Nature

Inner Space Cavern

Walk through an Ice Age cave 30 minutes from Austin. Paid entry. Best from about age 3. About two hours. Easy going.

Ages 3–18+
Cost Paid
Duration ~2h
Difficulty Easy
Setting Indoor

One of the best-preserved caves in Texas staying a constant 72 degrees year round which makes it a brilliant beat-the-heat option on a blazing Austin summer day. Kids are wowed by the massive stalactites and stalagmites on the one-mile paved Adventure Tour and the guides pace the experience well for families with younger children. The cavern was discovered in 1963 during highway construction and still contains Ice Age fossils of mammoths and giant sloths which gives kids something genuinely cool to talk about afterward. Tours depart every 20 to 30 minutes so you rarely wait long.
