Search Visit Montana

This park commemorates the discovery by the Lewis and Clark Expedition of the confluence of the Jefferson River, Madison River and Gallatin River, which has been designated as the official headwaters of the Missouri River. These rivers were named after President Jefferson, Secretary of State (and later President) James Madison, and Treasury Secretary Albert Gallatin, all of whom played significant roles in the Louisiana Purchase and the Lewis and Clark Expedition itself. The park is open year round and admission is charged.

To reach the park, travel 3 miles east of Three Forks on Interstate 90, then east on Secondary 205 and finally 3 miles north on Secondary 286.
