Mammoth Spring is Arkansas's largest spring and the second largest spring in the Ozark Mountains. A National Natural Landmark, the spring flows nine million gallons of water hourly. Forming a scenic 10-acre lake, it then flows south as the Spring River, a popular Ozark trout and float stream. Located near the spring, the park's 1886 Frisco depot will take you back in time to an early 1900s train station. Parked just outside the train station is a Frisco caboose to explore, too.

Here at the picturesque park, remnants of a mill and hydroelectric plant also reflect Mammoth Spring's history.

Park facilities include an information center that also serves as an Arkansas Welcome Center. Exhibits here share the story of the area's history and natural resources. Nearby are picnic sites, a trail, ball field, and children's playground.

There is an admission fee: Contact park for prices.

History of the Area
Located in Arkansas, the park is home to one of the world's largest springs. The spring flows nine million gallons per hour and forms a 10-acre lake.

Inhabited by Native Americans for thousands of years, it was later discovered by European explorers around 1812.

The Frisco Railroad purchased land surrounding the spring in late-19th century and built an elegant depot there.

A hydroelectric plant was constructed on site during this period which supplied power until its closure in 1972.

Arkansas acquired these lands from private owners between 1957 -1968 with efforts led primarily by Governor Orval Faubus.

It officially became part of Arkansas' state parks system after being transferred from Game & Fish Commission control in July,1985.

Today it features historical exhibits including restored buildings like train depot or mill along with recreational facilities such as trails and fishing areas.
Visitors can enjoy trout fishing in the clear, cold waters of Spring River. Common catches include rainbow and brown trout.
