THE HISTORY

A Cavern with Stories — from Lipan Apache to 1930s Public Tours

Cascade Caverns was known to the Lipan Apache in the 1700s; in the 1840s local youths carved initials in the first room, the cave became a private-touring site in the 1870s and opened to the public in 1932—artifacts and historic marks remain visible during the Aquifer Tour.

THE GEOLOGY

Active Dripstone and an Ancient Ocean Bed

The caverns preserve shells from when the area was an ocean bed over 100 million years ago, and the cave’s stalactites, stalagmites and draperies remain overwhelmingly active—about 95%—as water continues to shape the formations.

THE ROUTE

An Advanced, Far‑Below‑Surface Route with Signature Formations

The Aquifer Tour ventures deep into the cavern system for multiple hours and passes signature features such as the Diamond Ceiling, Hanging Tobacco, Giant Molar, Travertine Dam and Twin Sisters, guided by an experienced caver.
