A National Natural Landmark, Mammoth Spring is one of the world’s largest springs with nine million gallons of water flowing hourly. It forms a 10-acre lake then runs southward as the Spring River, a famous Ozark trout and float stream. Remnants of a mill and hydroelectric plant are part of Mammoth Spring’s history. The park also features an 1886 Frisco train depot and museum. Adding to the things to do here are a playground, picnic area, baseball field, walking trail, Arkansas Welcome Center, and gift shop. Pedal boats and kayaks are also available for rent.
One of the most scenic regions of Arkansas surrounds Mammoth Spring State Park. Along the Spring River and its tributaries, resorts and communities offer a variety of excellent facilities. A leisurely drive along paved rural highways will take you past free-flowing streams and towering bluffs to Ozark towns where you can browse for gifts of the unique arts and crafts made in this area. Adjacent to the park, the Federal Fish Hatchery and Aquatic Conservation and Education Center may be toured. Their aquariums offer a close look at fish and other aquatic species. Overnight lodging and camping are not provided at the park; however, motels and campgrounds are nearby, plus restaurants, groceries, and other conveniences. Canoe and boat rental, shuttle service, and fishing supplies are available along the Spring River.
