This hike, which allows you to see a small section of the underground karst world, is a great hike for young children or others interested in learning more about the Edwards Aquifer and the geology around Austin. Several small caves have been formed here by the collapse of sinkholes. Goat Cave, near the end of the hike, is home to a colony of bats. Entry is prohibited.
At the trailhead, stop at the kiosk to read about karst geol-
ogy and cave inhabitants, including troglobites, troglozenes,
and troglophiles. Several endangered species make these caves their home. All are adapted to living in a wet, humid, constant-temperature environment, and some have no eyes. Some are so small that it is difficult to see them without using magnification. Larger animals, spiders, snakes, and bats also use the sinkholes.
