About Mammoth Spring State Park

Mammoth Spring State Park features one of the largest natural springs in the United States, offering scenic beauty, rich history, and diverse recreational opportunities along the Spring River.

Wilderness Landscape & Natural Heritage

Mammoth Spring State Park is located in north-central Arkansas, adjacent to the town of Mammoth Spring. The park centers around Mammoth Spring, one of the largest natural springs in the country, which discharges an average of 9.78 million gallons of crystal-clear water daily into the Spring River. The spring and park cover roughly 33 acres, offering a peaceful setting that combines natural wonder with historic charm. Ecologically, the park supports a range of freshwater aquatic life and riparian vegetation, making it a popular spot for fishing, birdwatching, and photography.

Historically, the site housed a now-removed hydroelectric dam and mill, with remnants still visible, and the park showcases restored historic buildings including a large trout hatchery facility. Visitors can explore walking trails and enjoy picnicking areas overlooking the spring and river. The Spring River is well-known for fly fishing, floating, and kayaking. Apart from its natural features, the park includes a visitor center with educational exhibits about the spring's geology and local history.

Mammoth Spring State Park is appealing for families, anglers, and outdoor enthusiasts interested in gentle hikes, water activities, and nature observation in a convenient setting. The combination of outstanding water clarity, abundant wildlife, and historic infrastructure makes it a favored destination in Arkansas throughout spring, summer, and fall seasons.
