Discover more about Mammoth Spring State Park

Mammoth Spring State Park, located in the northern part of Arkansas where it borders Missouri, is a captivating destination blending natural wonder with historical significance. The park's centerpiece, Mammoth Spring, is the state's largest and one of the world's biggest natural springs, gushing approximately nine million gallons of water every hour. This incredible flow forms a scenic 10-acre lake that gives rise to the Spring River, a popular spot for trout fishing and canoeing. Visitors can explore the park's diverse attractions, including the well-preserved 1886 Frisco train depot, which now serves as a museum showcasing the region's railroad history. A vintage Frisco caboose sits outside the depot, offering a glimpse into the past. The park also displays the remnants of a mill and hydroelectric plant, illustrating the spring's historical importance as a power source. Beyond its natural and historical features, Mammoth Spring State Park provides various recreational opportunities. These include a playground, picnic areas, a baseball field, and a walking trail that loops around the lake. Pedal boat and kayak rentals are available seasonally for enjoying the water. The park also houses an Arkansas Welcome Center, offering travel information and a gift shop. The area has a rich history, with Native Americans, particularly the Osage, inhabiting the region for thousands of years. European settlers arrived in the early 1800s, calling the spring "Head of the River". The arrival of the St. Louis–San Francisco Railway (Frisco) in 1883 spurred the town's growth, with the spring powering various industries, including a flour production company. In 1925, the Arkansas-Missouri Power Company built a hydroelectric plant that operated until 1972. Mammoth Spring was established as a state park in 1957.
