Follow in the Footsteps of America's Greatest Expedition on the Lewis & Clark National Historic Trail

Embark on an epic journey through American history along the Lewis & Clark National Historic Trail, an extensive network of paths spanning thousands of miles across the landscapes that shaped our nation's westward expansion. This magnificent trail system, featuring 271 interconnected routes, traces the historic path of the Corps of Discovery's remarkable journey from 1804 to 1806, offering visitors a chance to experience the same awe-inspiring vistas that captivated these legendary explorers over two centuries ago. As you traverse the trail, you'll encounter iconic landmarks that tell the story of this momentous expedition, including the dramatic Gates of the Mountains with its towering limestone cliffs, and the culturally significant Heart of the Monster, central to Nez Perce tribal history. History comes alive at preserved campsites from May 1805, where you can stand in the exact locations where Lewis and Clark's team rested and planned their next moves. Don't miss the chance to see Clark's own signature etched in stone, or visit the historic "Buffalo Jump" at Slaughter River, where Native Americans conducted traditional buffalo hunts. The majestic Citadel Rock stands as a natural sentinel, offering the same impressive sight that greeted the explorers on their westward journey.
