How It All Began

Touring the Rushmore Cave the closest cave to Mount Rushmore


Let’s dive deep into Rushmore Cave. For years adventure seekers have been exploring this fascinating, underground world. The cave was discovered by accident in 1876 by area miners who were building a flume. Since no valuable minerals were found within the cave, the miners had little use for it. Their children, however, had a blast exploring the passages. Over time the cave became more and more popular as visitors flocked to experience it. In 1927 the cave officially opened as the Hermosa Crystal Cave. Eventually, under different ownership, the name was changed to Rushmore Cave and more additions and improvements were made to the attraction to make it the exciting adventure park it is today. 

The Cave Tour

A cave tour is the ideal way to cool off during a hot day, especially after exploring above ground. Rushmore Cave remains 58 degrees year-round due to it’s location – underground. Fun fact: caves remain unaffected by weather patterns and their temperature is somewhat related to the average temperature of the region. Underground, visitors will find different rooms such as the Big Room, the Floral Room, the Image Room and the Post Office. In these rooms you can discover beautiful cave formations like stalactites, stalagmites and helictites. The tour distance is a ½ mile and takes about an hour from start to finish. Along the way your tour guide will reveal hidden gems and walk you through the history of this intriguing cave.

*At this time Rush Mountain is only offering the guided walking tour, other tours they typically offer include the Spelunking Tour and Flashlight Tour.
