Available activities include camping, fishing, canoeing, and hiking. One of the crown jewels of the Ozark National Scenic Riverways, this unique and beautiful spring north of Eminence rises quietly into a nearly circular basin formed by the collapse of a cavern roof. The basin is deep and shaded, nurturing the growth of underwater mosses that tint the water a deep aquamarine. Part of the cave remains as a rock span through which the water flows into a spring branch that connects with the nearby Current River. Another portion of the cave is open to the public in summer and is rich in unusual geological formations.
Picnic facilities are scenic and spacious.
Mammoth Spring State Park, located just across the state line in Arkansas, is named for the largest spring in Arkansas and the tenth largest in the world. Emerging from a rock face 70 feet below the surface of the pool, the spring pours 9.78 million gallons an hour of cool, clear water into Spring Lake. It is also the headwaters of Spring River, a legendary trout stream. The spring was dammed in 1888 and a hydroelectric plant was constructed which was the area's first source of electrical power. The metal pylons that carried electricity all the way to West Plains can still be seen along the Burlington Northern railroad line.
