Onyx Cave Park is Arkansas’s oldest show cave — toured since 1891 — and one of the easiest, most family-friendly caves to explore near Eureka Springs. A self-guided audio tour lets you wander the cool, well-lit passages at your own pace, taking in the flowstone, cave formations, and a constant 57°F that feels wonderful on a hot Ozark day.
