Discover more about Mammoth Spring State Park

Nestled in the Ozark Mountains, bordering Missouri, Mammoth Spring State Park is a captivating destination where nature's grandeur meets historical charm. The park's centerpiece, Mammoth Spring, is Arkansas's largest spring and one of the world's biggest, with approximately nine million gallons of water flowing every hour. This incredible natural landmark feeds a scenic 10-acre lake and is the primary source of the Spring River, a popular spot for fishing and canoeing. Visitors can explore the park's diverse attractions, including the fully restored 1886 Frisco train depot, which now operates as a railroad museum. The museum showcases the impact of the railway on the region, with exhibits, artifacts, and life-size figures depicting the train crew, station workers, and passengers from the early 1900s. A vintage Frisco caboose sits nearby, offering a glimpse into the golden age of train travel. The park also preserves remnants of its industrial past, including a mill and hydroelectric plant. The Mammoth Spring Improvement Company constructed a dam in 1887 to power a local gristmill. Later, in 1925, the Arkansas-Missouri Power Company acquired the dam and built a hydroelectric plant, which operated until 1972. Visitors can still tour the old power plant and walk across the historic milldam. Other park amenities include a visitor center that doubles as an Arkansas Welcome Center, providing travel information, a gift shop, and exhibits. Guests can also enjoy a modular playground, picnic areas, a baseball field, and a walking trail that circles the lake and crosses the old milldam. Seasonal boat rentals, including pedal boats and kayaks, are available on the lake. With its stunning natural beauty and rich history, Mammoth Spring State Park offers a memorable experience for tourists seeking a blend of outdoor recreation and cultural exploration.
