Missouri Headwaters State Park Campground offers 17 campsites with fire rings and picnic tables at the confluence of the Jefferson, Madison, and Gallatin Rivers, featuring a boat ramp and direct river access for fishing, kayaking, and canoeing.

The campground provides vault toilets, drinking water, and a camp host, with both first-come, first-served and reservable sites available year-round.

Be prepared for significant mosquitoes during summer months, particularly at sites near marshy areas, and note that all watercraft must be inspected before launching per Montana regulations.
