“The Lewis and Clark Expedition is more than the story of two men. It is the story of many: individuals and groups, military men and scientists, a president and a slave, women and men, French-speaking boatmen and American Indians. It is a story of loss and hope. It is a story of changes that began in 1803 and that continue today.” ~ U.S. National Park Service
The Lewis and Clark National Historic Trail, administered by the National Park Service, is more than 4,900 miles long, traversing sixteen states and many tribal lands, along the historic route of the expedition. Lewis and Clark National Historic Trail was designated by Congress to commemorate the 1804 to 1806 Corps of Discovery expedition through the identification; protection; interpretation; public use and enjoyment; and preservation of historic, cultural, and natural resources associated with the expedition and its place in U.S. and tribal history. This epic journey contributed significant scientific knowledge and profound political, social, economic, cultural, and environmental changes to the peoples and landscapes of the North American continent.
The Trail has over 6,600 miles of designated auto tour route which provides visitors access to the historic route through rich recreational, interpretive, and educational opportunities. Many segments of Lewis and Clark National Historic Trail retain landscape characteristics and a sense of place as seen and experienced by the Corps of Discovery. The Trail links contemporary authentic communities and cultures, including tribes whose connections span thousands of years, to historic, vibrant and living landscapes. Whether traveling the entire length of the Trail or a short day trip to a small segment, your travel experience can be greatly enhanced by the amazing possibilities highlighted on this website.
