Ruby Falls Caves and Karst Day Icon

National Day of Caves and Karst

Along with the National Caves Association, Ruby Falls celebrates National Day of Caves and Karst! Visit Ruby Falls during this annual event and take part in educational activities designed to increase awareness of the important role caves and karst play in our lives and environment, meet special guests, and take home a complimentary keepsake. 

CaveSim at Ruby Falls  June 6 - 8, Ruby Falls guests will have the unique opportunity to experience CaveSim, a simulated cave that teaches the importance of caving safely and softly; without harming caves, causing personal injury, or hurting other cavers. The realistic simulator uses science, technology, engineering and math to demonstrate best-practice caving skills interactively. Crawl through the 60-foot, multi-level passage while the CaveSim computer monitors when formations are bumped or brushed. Each explorer earns a final score based on how successfully they safely navigated the simulated cave journey.
