Onyx Cave Eureka Springs Arkansas

Whether you’re a dedicated subterranean or just looking for something fun and unique to do, you can’t go wrong with a visit to Eureka Springs’ Onyx Cave.

Fans of caves, history, and geology will enjoy touring Onyx Cave, Arkansas oldest show cave. The attraction opened to the public in 1893 and has been fascinating visitors ever since.

The cave’s name comes from all the strange and wonderful flowstone formations found inside. Flowstone, once known as “cave onyx,” is created when calcium carbonate rich water flows along the walls or floor of a cave. The water slowly deposits layers of calcite, creating smooth, glossy looking formations that can take many shapes.

Because of its considerable age as a public attraction, Onyx Cave does display some unfortunate wear. In the early days, visitors didn’t think twice about reaching out to snap off a souvenir. The cave was also used for a few scenes in “It’s Alive,” a 1969 science fiction, b-movie. In spite of this, the cave is still a fascinating and excellent diversion for the whole family.
