The Yellowstone River is one of the most iconic rivers in the United States, known for its stunning scenery, important role in the ecosystem, and historic significance. Flowing through Yellowstone National Park and beyond, it offers breathtaking landscapes, world-class fishing, and exciting opportunities for adventure. But just how long is the Yellowstone River, and what makes it so special? In this post, we’ll explore the length, path, and key features of this incredible river.
The Length of the Yellowstone River
The Yellowstone River is 692 miles (1,114 kilometers) long, making it the longest undammed river in the continental United States. It flows freely from its source in the Rocky Mountains all the way to its confluence with the Missouri River.
The Yellowstone River’s Journey
The river’s journey takes it through three states:
Wyoming – The river begins in Yellowstone National Park.
Montana – It winds through scenic valleys and famous fishing areas.
North Dakota – It eventually joins the Missouri River.
1. The Source: Yellowstone National Park
The Yellowstone River starts in the Absaroka Range of the Rocky Mountains in northwest Wyoming. It flows through Yellowstone Lake, the largest high-elevation lake in North America. As it exits the lake, it forms the Upper and Lower Yellowstone Falls, some of the most famous waterfalls in the United States.
Many visitors on Yellowstone private tours stop at the Grand Canyon of the Yellowstone, where the river has carved deep, colorful cliffs over thousands of years.
2. Montana: Wide Valleys and Fishing Hotspots
After leaving Yellowstone National Park, the river enters Montana, flowing through Paradise Valley, a well-known area for fly fishing. The river continues past the city of Billings, the largest city in Montana, before moving into eastern Montana’s prairie landscapes.
The Yellowstone River is famous for trout fishing, and Montana is one of the best places to experience it. Visitors can book Yellowstone private tours for guided fishing trips along this stretch of the river.
3. North Dakota: Meeting the Missouri River
The river crosses into North Dakota, where it eventually meets the Missouri River near the town of Williston. This confluence marks the end of the Yellowstone River’s journey, but its waters continue to flow toward the Mississippi River and, eventually, the Gulf of Mexico.
