Mammoth Spring State Park, Delta Travel Guide

Mammoth Spring State Park, a 62.5-acre haven in Fulton County, Arkansas, centers around the state's largest spring and a National Natural Landmark. This natural wonder pumps approximately nine million gallons of water every hour, feeding a 10-acre lake that becomes the source of the Spring River, a popular destination for fishing and canoeing.The park's history is as captivating as its natural beauty. The area was originally inhabited by Native Americans, particularly the Osage, and later settled by Europeans in the early 1800s. The spring, initially called "Head of the River," quickly became a local attraction. In 1883, the arrival of the St. Louis–San Francisco Railway (Frisco) spurred growth, and a dam was constructed to power a flour mill. The town flourished, drawing summer tourists to a 56-room resort and cabins. In 1903, one of the earliest national fish hatcheries was established.In 1925, the Arkansas-Missouri Power Company acquired the dam rights and built a hydroelectric plant, which operated until 1972. The park was approved in 1957, but land acquisition continued until 1975. Today, visitors can explore the fully restored 1886 Frisco train depot, complete with exhibits, memorabilia, and life-size figures depicting the railway's impact on the region. A vintage Frisco caboose sits nearby. The park also features a welcome center, playground, picnic areas, and a walking trail that loops around the lake and crosses the old milldam. Visitors can tour the old power plant and learn about the spring's role in generating electricity.
