Mammoth Spring State Park is a park surrounding Mammoth Spring. The park is located in Mammoth Spring, Arkansas.
The park contains a hydroelectric dam, Mammoth Spring, a train museum including a Frisco caboose, a playground, and also allows visitors feed ducks and geese in the park.
Prior to 1957, the Mammoth Spring Cattle Sales Barn was co-owned and ran by local entrepreneur Kenneth "Bert" Bishop and his associate, roughly on the site of where the tourist information center now stands. Local farmers would routinely come to the site to sell livestock and other wares, such as Howard Green, who sold home-made walking sticks. Following this period in history, the State legislature voted to condemn the land and turn the spot into a state park. 1957, the park was established. The original Frisco Depot was restored in 1971. The depot now functions as a museum, containing artifacts and memorabilia.
