Mammoth Spring is a National Natural Landmark and one of the world's largest springs, with nine million gallons of water pouring every hour. It produces a 10-acre lake before flowing south as the Spring River, a popular trout and float stream in the Ozarks. The history of Mammoth Spring includes the ruins of a mill and a hydropower station. A playground, picnic area, baseball field, walking route, Arkansas Welcome Center, and gift store are also available. At all times, dogs must be leashed.
