Missouri Headwaters State Park

Camp where Lewis and Clark stayed in 1805. This park encompasses the confluence of the Jefferson, Madison and Gallatin Rivers.

About the Park

Within the boundaries of this scenic park and National Historic Landmark, the Jefferson, Madison, and Gallatin rivers merge to form the 2,300 mile Missouri River.

Considering it an essential point in the geography of this western part of the continent, Meriwether Lewis wrote the country opens suddenly to extensive and beautiful plains and meadows which appear to be surrounded in every direction with distant and lofty mountains. The legendary Sacajawea was captured here as a child and eventually returned as a member of the Corps of Discovery. Another member of this expedition, John Colter, later made several trips to this area in search of furs and began his famous run nearby. Pioneers slowly settled the surrounding area and transformed it into profitable grazing and farming land. Missouri Headwaters State Park preserves much of the region's abundant wildlife, lush, vegetation, and scenic beauty that have attracted people for thousands of years.

The park provides 17 campsites, tipi rental, foot trails to points of interest, and interpretive displays of the area's cultural and natural history. River floating, fishing, picnicking, bicycling, hiking, interpretive programs, and photography are popular activities.


Missouri Headwaters State Parks offers a Summer Speaker Series presenting a variety of topics each week that are open the the public. You can view the 2023 schedule here


The park is 532 acres in size and is 4,045 feet in elevation.

2021 Missouri Headwaters State Park Master Plan

Montana Fish, Wildlife & Parks is developing a master plan for Missouri Headwaters State Park and is seeking public input on current and future usage and needs for the park. This effort includes several goals:

  • Guide the development and use of park facilities.

  • Provide guidelines for the protection and management of important natural, cultural and scenic resources.

  • Provide visitors with a wide range of experiences.

  • Provide for public health and safety.

  • Address short-term and long-term needs, while making the least impact on the landscape and cultural resources.

  • Broaden visitors’ knowledge and appreciation of the area.

  • Accommodate crowds while still allowing for areas of solitude.

Those wishing to provide input on issues considered in the master planning process can do so through an online survey available at Missouri Headwaters State Park Master Plan - Public Survey.
