Lewis & Clark National Historic Trail
Project Partners
Follow in the footsteps of America's most famous explorers along the Lewis & Clark National Historic Trail, an extraordinary journey spanning over 4,300 miles of pristine wilderness and historical landmarks. This remarkable trail system traces the historic route of the Corps of Discovery's 1804-1806 expedition, taking modern-day adventurers through eleven states from Illinois to the Pacific Coast. Along the way, you'll encounter landscapes that have remained largely unchanged since Lewis and Clark first ventured through these territories over two centuries ago. Visitors can explore 253 distinct trails and discover iconic sites like the majestic Gates of the Mountains in Montana, where limestone cliffs tower over the Missouri River, and Citadel Rock, an imposing natural landmark that captivated the explorers. The trail features numerous historic campsites, including the May 28th, 1805 location where the expedition made crucial discoveries. Don't miss the fascinating "Buffalo Jump" at Slaughter River, an archaeological site that tells the story of Native American hunting practices, or the legendary Heart of the Monster, a sacred Nez Perce site steeped in cultural significance. History enthusiasts will be particularly moved by Clark's Signature, one of the few remaining physical marks left by the explorers themselves.
