Surrounded by lush plains and meadows and backdropped by distant majestic mountains, Missouri Headwaters State Park is a breathtaking area. It lies at the confluence of the Jefferson, Madison, and Gallatin Rivers, which unite to form the mighty Missouri River. In addition to preserving the area’s vibrant scenic beauty, the park also memorializes the local history.  

In July 1805, Meriwether Lewis and William Clark of the Corps of Discovery camped in this area. While there, they noted the as being home to the Blackfeet Nation, as well as numerous grizzly bears. They also saw it as being of strategic importance to the United States government and recommended a fort be built along the river. It was also at this location that the Hidatsa tribe captured Lewis and Clark’s native guide, Sacagewea.  

While a military fort was never built, a group of fur traders from the Missouri Fur Company did establish a makeshift cottonwood structure here known as Fort Three Forks in 1810 with the intent of making it a trading post. Within a few months, however, they abandoned the endeavor after conflicts with the native people. In 1960, the site was designated the Three Forks of the Missouri National Historic Landmark.  

Missouri Headwaters State Park is open year-round. For those looking to stay overnight, there are 17 campsites available, along with tipi rentals. Several foot trails lead to scenic spots and other points of interest. Visitors can also enjoy fishing, canoeing, floating on the river, swimming, bicycling, and picnicking. Interpretive programs are also available.
