Mammoth Spring State Park

Mammoth Spring State Park is a recreation area in Fulton County with a renovated Victorian train depot from 1885 and a lake formed by a limestone dam. The grounds include walking trails along the Spring River and offer various activities for visitors.

The property was acquired in 1925 by the Arkansas-Missouri Power Company, which built and operated a hydroelectric facility that generated power from 1925 until 1972. During these decades, the installation was a key energy supplier for the region.

The renovated Frisco train depot operates as a museum and displays regional artifacts along with railway memorabilia from the era of early railroad expansion. Visitors can explore in the rooms how the rail line shaped local development and connected the region to broader transportation networks.

The park offers a visitor center, walking trails, boat rentals, and fishing areas around Spring Lake. Visitors should wear comfortable shoes and prepare for changing weather conditions depending on the season.

Mammoth Spring has an underground source that discharges about 9 million gallons of water per hour, fed by a river system flowing beneath Missouri. This natural phenomenon makes the place a striking example of the power of underground waters in the region.
