Fodor's Expert Review Missouri Headwaters State Park
Three Forks
The Madison, Jefferson, and Gallatin rivers come together to form the mighty Missouri River within Missouri Headwaters State Park, a National Historic Landmark. At 2,340 miles, the Missouri is the country's longest river. Lewis and Clark named the three forks after Secretary of the Treasury Albert Gallatin, Secretary of State James Madison, and President Thomas Jefferson. The park has historical exhibits, interpretive signs, picnic sites, hiking trails, and camping.
