There's no denying Yellowstone is one of America's — and the world's — great national parks. There are great alternative options for crowd-weary park enthusiasts, though, one of which is Missouri Headwaters State Park, just across the Wyoming border in Montana. Missouri Headwaters State Park, only 30 minutes from Bozeman by car, sits at the point where three smaller rivers converge to form the Missouri River, which then winds cross country for some 2,500 miles before flowing into the Mississippi at St. Louis. Missouri Headwaters is a highland area of verdant plains, webbed in great, snaking tributaries and dotted with willow, cottonwood, and birch trees. Other activities include cycling, fishing, kayaking and boating, and a summer speaker series featuring free-to-attend presentations on the history and nature of Missouri Headwaters.
