Mammoth Spring is Arkansas's largest spring and the second largest spring in the Ozark Mountains. A National Natural Landmark, the spring flows nine million gallons of water hourly. Forming a scenic 10-acre lake, it then flows south as the Spring River, a popular Ozark trout and float stream. Located near the spring, the park's 1886 Frisco depot will take you back in time to an early 1900s train station. Parked just outside the train station is a Frisco caboose to explore, too.
Here at the picturesque park, remnants of a mill and hydroelectric plant also reflect Mammoth Spring's history.
Park facilities include an information center that also serves as an Arkansas Welcome Center. Exhibits here share the story of the area's history and natural resources. Nearby are picnic sites, a trail, ball field, and children's playground.
There is an admission fee: Contact park for prices.
