Grand Caverns, National Natural Landmark cave system in Grottoes, Virginia.
The limestone cavern extends over 19,957 feet underground, featuring Cathedral Hall with dimensions of 280 feet long and 70 feet high.
Discovered in 1804 by Bernard Weyer while searching for a missing trap, the cave walls contain 230 signatures from Civil War soldiers dated 1864.
The Grand Ballroom within the cave system hosts traditional dancing events during the annual Fall Festival Living History Day in October.
The cave maintains a constant temperature throughout the year and offers three different spelunking adventures: Rock Bottom, Grottoes Crawl, and The Gauntlet.
The cave system contains numerous shield formations, with certain passages displaying white crystalline deposits that earned the section the name New Mexico.
