From the Plains to the Pacific

Between May 1804 and September 1806, 31 men, one woman, and a baby traveled from the plains of the Midwest to the shores of the Pacific Ocean. They called themselves the Corps of Discovery. In their search for a water route to the Pacific Ocean, they opened a window onto the west for the young United States.
Hiking on the Trail.

Explore the Trail

Tracing the courses of the Missouri and Columbia rivers, the Lewis and Clark National Historic Trail stretches through 11 states. The Trail winds over mountains, along rivers, through plains and high deserts, and extends to the wave-lapped Pacific coast. In this diversity of landscapes, visitors to the Trail create their own journeys of discovery.

Certified Sites

A moratorium on site certification is in place pending legal review by a National Park Service Solicitor. The certification of non-federal Trail segments is not affected by the moratorium. Also, the Trail's official logo, to the left, is protected by federal law and may not be used in any form or version, in whole or in part, without the written permission of the Trail Administrator.
