Cosmic Cavern was discovered in 1845, but wasn'€™t developed until 1927. The cave features a 9 foot soda straw the longest known in the Ozarks, and two bottomless lakes. One of the lakes was discovered in 1993 in the "Silent Splendor" section which made national news. This was Arkansas’ most delicate discovery. Make sure to bring your camera! Gift Shop, Snacks, Picnic area and camping available.Cosmic Cavern was discovered in 1845, but wasn'€™t developed until 1927.
