The Lewis River is a cool river that flows for about 18 miles (29 km) in Yellowstone National Park, Wyoming, United States. It's a branch of the much larger Snake River. This river got its name from Meriwether Lewis, a famous explorer who led the Lewis and Clark Expedition.

Exploring the Lewis River

The entire Lewis River is located inside the amazing Yellowstone National Park. It's a beautiful and wild place to explore.

Where the River Flows

The Lewis River starts at the southern end of Shoshone Lake. From there, it flows south for about 3 miles (5 km) until it reaches Lewis Lake. This short part of the river is the only section where people are allowed to go boating.

After leaving Lewis Lake, the river continues flowing south. It winds through a deep canyon, running alongside the park's south entrance road. The river then passes over several small waterfalls and exciting rapids. One of the most famous spots is Lewis Falls.

Just before it leaves the park, the Lewis River joins up with the Snake River. This meeting changes the Snake River's path, making it flow more to the south. Soon after, the Snake River leaves Yellowstone and flows into Grand Teton National Park and Jackson Lake.

Exciting Waterfalls and Rapids

The Lewis River is known for its thrilling rapids. Some parts of the river have rapids that are considered very difficult, up to Class VI. This means they are only for expert kayakers or rafters.

One of the most famous spots is Lewis Falls. Here, the river drops about 29 feet (9 meters) in a beautiful waterfall. There are many other smaller waterfalls and rapids along this scenic river, making it a great place to visit.

Fish You Can Find

If you enjoy fishing, the Lewis River is home to several types of trout. You might find Brown trout, Rainbow trout, and Yellowstone cutthroat trout swimming in its waters.
