RV route guide
Lewis & Clark expedition retrace
RV-friendly route following the 1804-1806 Corps of Discovery. With honest framing of Indigenous impact.
The Lewis and Clark Expedition (Corps of Discovery, 1804-1806) traveled 7,800 miles from St. Louis to the Pacific Ocean and back. The NPS Lewis and Clark National Historic Trail interprets the route across 11 states. The RV-driveable retrace covers about 4,000 miles east-bound or west-bound through MO, KS, NE, SD, ND, MT, ID, WA, OR. This is one of the great heritage routes — but the heritage is more complex than the 19th-century mythology suggests.

Can I drive the Lewis & Clark Trail in an RV?
Approximately. The actual trail traveled by the Corps of Discovery was rivers (Missouri + Snake + Columbia) and overland portages. Modern highways parallel the route. From St. Louis, follow I-70 + I-29 + I-90 + US-2 + I-90 west. About 4,000 miles RV-friendly. Multiple NPS Lewis & Clark interpretive sites along the route. Plan 28-42 days minimum.

The honest history
The Lewis and Clark Expedition is celebrated in American mythology as exploration. For the Indigenous nations the Corps encountered — Mandan, Hidatsa, Lakota, Salish, Nez Perce, Shoshone, Chinook, and many others — the expedition was the first contact in a process that would dispossess them of their lands within decades.
Sacagawea — the Shoshone woman whose translation made the expedition viable — is often reduced to a mythologized figure. The actual person was a young woman, married into the expedition, navigating between cultures under duress.
Travel with awareness. NPS Lewis and Clark interpretation has improved in recent years and now includes Indigenous perspectives. Visit the Bismarck ND area Mandan-Hidatsa villages (Knife River Indian Villages NHS) and the Salish-Kootenai Cultural Center on the Flathead Reservation. Engage the full history, not just the mythology.
