One of the largest springs in the country pours out of the ground into a calm lake beside an old railroad depot. A short flat path circles the water, and the stop works well as a picnic break on the Missouri border.

The spring in Mammoth Spring State Park discharges about 9 million US gallons per hour (roughly 34,000 cubic meters) and is among the largest springs in the world. It has been a National Natural Landmark since June 1972. A dam built in 1887 impounds it as Spring Lake; it first powered a mill, and a hydroelectric plant generated electricity until 1972. The 62.5-acre (about 25-hectare) park was approved as a state park in 1957, though the first land was not acquired until 1966.

Beside the lake stands the Frisco railroad depot, built in 1886 and now a museum; there is also an Arkansas Welcome Center. You can stroll along the water, picnic and, in season, rent pedal boats. One to two hours is enough for a stop.
