Montana’s Superfund-to-State-Park Restoration — 635 Acres at the Clark Fork & Blackfoot River Confluence, Interpretive Trails, Fishing, Paddling & Lewis and Clark History Near Missoula

Milltown State Park is a 635-acre day-use park at the confluence of the Clark Fork and Blackfoot Rivers in Missoula County, Montana. The park celebrates one of America’s most remarkable environmental restoration stories — the Milltown Dam removal and Superfund site remediation that returned two rivers to their free-flowing state after over a century. Today, the park offers interpretive trails and displays, river access for fishing and paddling, panoramic overlook views, wildlife viewing, and connections to the region’s deep indigenous, exploration, and geological history.

The park encompasses restored river bottoms, cottonwood stands, pine-forested bluffs, and dramatic rock cliffs. The Milltown area is the ancestral homeland of the Salish and Kalispel peoples, who recognized the confluence as a key site for bull trout. Meriwether Lewis of the Corps of Discovery passed through on July 4, 1806. The landscape was also shaped by the massive floods of Glacial Lake Missoula thousands of years ago. For visitors near Missoula, Milltown delivers a powerful combination of environmental education, river recreation, and Montana scenery.
