Things to do:

Just outside of Three Forks, you’ll find Missouri Headwaters State Park, the confluence of the Madison, Jefferson and Gallatin rivers which form the 2,300 mile Missouri River.

At Missouri Headwaters State Park, you can still find the area looking much as it did historically - with much of the region's abundant wildlife, vegetation, and scenic beauty preserved - making it clear what has attracted people for thousands of years.

  • Looking to camp in history? There are 17 campsites available and you can even rent a tipi!
  • Interpretive displays describing the area’s cultural and natural history can be found to help guide you!
  • Take your bike for a spin on the many trails throughout the park!
  • Not much of a biker? Use the trails for a scenic hike instead!
  • Take a float down the river, you’ll have your choice of three!
  • Visit Fort Rock to take a look at historic pictographs. 

The three rivers that converge to form the Missouri River are named for President Thomas Jefferson, Secretary of State James Madison and Treasury Secretary Albert Gallatin!

The rich, fertile soil along with the proximity to fresh water, brought the Flathead, Bannock and Shoshone Indians to the region and later trappers and settlers, and now this beautiful land has been preserved as a state park for visitors just like you. 

Known for an abundance of wildlife, Missouri Headwaters State Park is a great place to explore, but don’t forget your bug spray! 

In addition to its vast natural resources and outdoor activities, Missouri Headwaters State Park also boasts extensive cultural history - ranging from the tribes that lived there beginning 3,000 years ago to Lewis and Clark to fur traders to settlers.

In late July 1805, William Clark and a small number from the Corps of Discovery reached the Headwaters while scouting for Shoshone Indians, whom they hoped would sell them horses. It was Sacajawea, who recognized the area as where she was captured as a child by the Hidatsa, that led the expedition successfully there.

While at the confluence, Clark left a note for Meriwether Lewis to find and later, Lewis Rock was named for him.

Curious what other visitors have had to say about the park?

"Very interesting spot to see three rivers come together to make the start of the Missouri River."

"Great campground and great camp host! Paul is awesome and hilarious! He also recommended good fishing spots and filled us in on the local moose population, (phone pics included!) This area is spectacular for bird watching, fishing, hiking and taking in some informative L&C history. Restrooms were spotless and smelled nothing like a vault toilet. Even enjoyed a lightning storm on our last night to wrap it all up. Great entertainment! We’ll probably be back in the fall with our little retro trailer for more fishing, exploring and dry-camping."

"We made a spur of the moment trip with 5 other couples from the Bitterroot Valley . Arrived and were met by the campground host, who was not only a character, but had this park and facilities absolutely spit- shined! The "Dogs on leash" rule is strictly enforced, but makes for a more enjoyable stay for all. My two Labradors liked the Host and the camping. Highly recommend."

"Quiet evening to enjoy the view. Be sure and climb up Fort Rock and enjoy the vistas from a little higher up. Easy walk up."
