Mammoth Spring, Arkansas’s largest spring, flows nine million gallons of water hourly. Forming a scenic 10-acre lake, it then flows south as the Spring River, a popular trout and float stream. Near the spring, the 1886 Frisco depot will take you back to the early 1900s. Just outside the train station is a Frisco caboose to tour also.
