Lewis & Clark National Historic Trail
Imagine standing on the banks of the Missouri River more than 200 years ago. When Meriwether Lewis and William Clark set sail to explore the newly-purchased Louisiana Territory the wide-open landscape they encountered didn’t look like the well-settled Iowa we know today.
This national historic trail traces the Lewis & Clark Expedition through through 16 states and over 4,900 miles. Iowa's leg of the trip is marked by Lewis & Clark Trail signs along Interstate 29 as it follows the Missouri River from Council Bluffs to Sioux City.
Find trail information and maps at any of the attractions along the trail.
