Onyx Cave ArkansasCome explore Arkansas’ oldest show cave. Onyx Cave, just outside Eureka Springs, AR has been attracting tourists since 1893!

Arkansas is riddled with naturally occurring caves. They can be found all over the state. Some are big and some are small but all of them are fascinating to those of us who like caves. If you consider yourself a cave lover, you won’t want to miss a chance to explore one of Arkansas’ the oldest show caves, Onyx Cave.

Arkansas’ Oldest Show Cave

Onyx Cave was discovered in 1891 and was turned into a show cave in 1893.

The cave got its name from the number of flowstone formations found inside of it. Flowstone, once commonly referred to as “cave onyx,” is a smooth, sheetlike formation found in caves. Minerals deposited by flowing water over thousands of years make up the weird shapes. Flowstone typically contains calcite or other carbonate minerals, not onyx. Despite this, numerous caves around the country have “onyx” in their names from the flowstone found within.

In the early days, show caves were not treated with the same respect and understanding that they are today. Back then, folks didn’t think twice about reaching out and snapping off a souvenir or two during their visit to show the folks back home. I guess they never considered how many people might do the same after them, or how many millennia their little keepsake took to be made – much less replaced.
