The Lewis and Clark Expedition


The trail that Captain Meriwether Lewis and Captain William Clark followed weaved its way through Idaho as shown on this map. Thirty-three people traveled with them into unknown territory, starting near what is now known as Wood River, Illinois in 1804, reaching the Pacific Ocean in 1805 and returning in 1806. Today's trail follows their route as closely as possible given the changes over the years. It is approximately 3,700 miles long, beginning near Wood River, Illinois, and passes through portions of Missouri, Kansas, Iowa, Nebraska, South Dakota, North Dakota, Montana, Idaho, Oregon, and Washington. The Lewis & Clark NHT does not have a formal visitor center along any portion of the trail. Various organizations and individuals are responsible for trail stewardship with oversight provided by the Lewis & Clark National Historic Trail office.
