Meramec Caverns is a 4.6-mile-long cavern system in the Ozark Mountains near Stanton, Missouri. The caverns were created by millions of years of water eroding the limestone rocks. Today, Meramec Caverns is the largest commercial cave in Missouri and a major tourist attraction on famous Route 66. The cave system has seven levels and is best explored by taking one of the guided tours led well-trained rangers. Some of the most popular attractions are the Wine Room with its famous Wine Table, which is a 6-foot high onyx table; a sheet wall cavern called the Greatest Show Under the Earth, where the popular show is run; the Mirror Room, a cavern with a 1.5-foot deep stream of water that mirrors the cavern’s ceiling; and many others.
