[1] The cave is located 40 mi (64 km) from downtown San Antonio, and 10 miles northeast of Boerne off FM 474 and Kreutzberg Road.

The cave went largely unnoticed again until the 1920s during the era of Prohibition, when a small moonshine distillery was installed in the uppermost cavern.

The main set of chambers open to the public make up the show cave, extending just over a quarter of a mile.

This part of the cave consists of six large, well-lit rooms full of speleothems, including stalactites, stalagmites, helictites, columns, and draperies.

Due to the great natural acoustics created by three large solution domes on the ceiling of the Throne Room, the cave is host to 12 concerts yearly with a maximum attendance of 200 people.

The music events vary from classical musicians, folk, Broadway, opera, and seasonal vocal groups.

The gift shop features a large selection of rocks, stones, and fossils for sale, including numerous amethyst cathedrals, jewelry, and more.
