The small Onyx Cave near Eureka Springs is the oldest show cave in Arkansas. Unfortuantely it is also very much damaged, by more than a century of public visitation.

Onyx Cave may be toured on self guided tours, the explanations are sent to the visitors with short range FM transmissions from small transmitter boxes all over the cave. The cave is entered through the only entrance, and after reaching the far end the visiturs have to go back the same path.
