Greer Spring consists of two springs. The upper spring comes from a small cave on the east side of the gorge. About 100 feet downstream the second or lower spring bubbles forcefully to the surface. The water at this point is deep and aqua blue. The rocks are covered with moss and due to the force of the springs the water has large amounts of cotton candy whitewater. Greer Spring is secluded and requires a step downward one mile serpentine hike to get to it but worth the trip. The spring is the second largest spring in the Ozarks, with Big Spring being the largest and is; located in neighboring Carter County.
