Lewis and Clark National Historic Trail is approximately 3,700 miles long, extending from Wood River, Illinois, to the mouth of the Columbia River, near present day Astoria, Oregon, following the historic outbound and inbound routes of the Lewis and Clark Expedition. The trail connects 11 states (Illinois, Missouri, Kansas, Iowa, Nebraska, South Dakota, North Dakota, Montana, Idaho, Washington, and Oregon) and many Tribal lands.
To learn more about this expedition or plan your own trip following the trail, stop into the trail headquarters. Lewis & Clark NHT is located within the National Park Service Midwest Regional Office along the beautiful riverfront in Omaha, NE, right next to the Bob Kerrey pedestrian bridge. The Visitor Center is open daily in the summer and Monday - Friday in the winter.
