About Mammoth Spring State Park

The park surrounds Mammoth Spring, a National Natural Landmark that releases a very large volume of water each hour. That water fills a 10-acre lake and then flows south as the Spring River, which anglers and floaters know for trout. Visitors can see remains of an old mill and a hydroelectric plant tied to the site's past. A restored 1886 railroad depot now houses a museum, and the grounds include a visitor center, a welcome center with a gift shop, a playground, picnic areas, a baseball field, and a walking trail.
