Overview

About This Attraction

Enter Nevada's longest cave system through illuminated limestone chambers where crystalline shield formations and glittering speleothems fill the underground passages. Shield formations—thin, blocky mineral deposits—build up where mineral-rich water seeps through ceiling and wall fissures, a visible record of ongoing geological work still happening today. Access is exclusively through daily ranger-led tours, with expert guides explaining the cave's mineralogy and million-year development across maintained underground pathways. Tours operate year-round except Thanksgiving, Christmas, and New Year's Day; reservations through recreation.gov are essential as tours regularly sell out.
