Onyx Cave
A small limestone cave discovered in 1891, where visitors can explore on their own with an audio guide and see stalactites and flowstone resembling onyx.
This is one of the earliest caves in Arkansas to open to the public. Its highlights are layered calcite flowstone, known as “onyx,” and stalactites. Visits are self-guided with an audio guide and take about 30 minutes. The path is gentle, making it suitable for families with children. Outside the cave there are small exhibits, including a museum of antique buttons. Adult admission costs about $10. The cave is seasonal, with shorter hours in winter. It is about 8 km northeast of town via Highway 62 and requires a car.
