Missouri Headwaters State Park

Where the Jefferson, Madison, and Gallatin rivers meet to form the Missouri River, a site Lewis and Clark's expedition reached in 1805.

Near the small town of Three Forks, the Jefferson, Madison, and Gallatin rivers meet to form the source of the Missouri River, one of the longest rivers in North America. In 1805, the Lewis and Clark Expedition arrived here and named the three rivers after the president and other officials of the day. The site is now a National Historic Landmark. The park has trails, interpretive signs, a lookout rock outcrop, and small patches of ruins from a former townsite. Visitors can go boating, fishing, and camping. A small day-use fee applies (free for Montana license plates). It is about 50 km from Bozeman.
