The cave was originally known as Weyer's Cave, named after Bernard Weyer, who discovered it while hunting in 1804.
It is home to an unusually high density of shield formations, a specialized type of stalactite deposit.
During the American Civil War, soldiers from both sides visited the cave, leaving behind charcoal and carved graffiti that remains visible today.
The cave features the 'Grand Ballroom,' one of the largest rooms in the cavern, which was used for events in the 19th century.
The temperature remains consistent throughout the entire year, regardless of external weather conditions.
Grand Caverns is a natural limestone cave system located in Grottoes, Virginia, notable for being the oldest show cave in the United States, open to the public since 1804. The cavern is recognized as a National Natural Landmark due to its extensive collection of shield formations, which are rare in many other cave systems. The interior maintains a constant temperature of approximately 56 degrees Fahrenheit year-round. Visitors tour the cave via a guided walking path that spans roughly one mile. The cave contains a historical 'Graffiti Room' featuring signatures of Civil War soldiers from both the Union and Confederate armies. The site is situated within a regional park that offers additional amenities, including walking trails and picnic areas.
