Blanchard Springs Caverns, Show cave in Arkansas, United States.
Blanchard Springs Caverns is a limestone cave system in Stone County, Arkansas, United States. The site spreads across multiple levels with chambers filled with white formations, underground streams, and natural columns.
The U.S. Forest Service opened the system to visitors in 1973 after installing walkways and lighting. However, exploration began in the 1950s when cavers started mapping the passages.
The name comes from Blanchard Springs, a nearby water source. The cave sits within the Ozark-St. Francis National Forest and supports several bat species.
The temperature stays around 58 degrees Fahrenheit (14 degrees Celsius) year-round, so bringing a light jacket helps. Sturdy footwear works well on the damp paths inside.
An active underground river continues to carve new passages through limestone dissolution. Visitors can hear and see flowing water in some sections.
