Lewis and Clark National Historic Trail

Lewis and Clark National Historic Trail

The Lewis and Clark National Historic Trail is approximately 3,700 miles long, extending from Wood River, Illinois, to the Pacific Ocean in Oregon, following both the outbound and inbound routes of the Lewis and Clark Expedition. This trail commemorates the 1804-1806 expedition of Lewis and Clark and the Corps of Discovery, which explored the Louisiana Territory and beyond. This epic journey contributed to significant scientific knowledge and profound political, social, economic, cultural, and environmental changes to the lands and the peoples of the North American continent.
