Overview
Lolo Pass is one of the most historically significant mountain crossings in the northern Rocky Mountains, linking present-day Montana and Idaho through the rugged Bitterroot Range. For centuries, the route served as a travel corridor for Native peoples, particularly the Nez Perce, who used it to move between the plains and the Pacific Northwest. In 1805 and again in 1806, the Lewis and Clark Expedition traversed this challenging landscape, enduring harsh weather, steep terrain, and food shortages while searching for a practical route across the continent. Their experiences at the pass became an important chapter in the story of American exploration.
Today, visitors can experience the same mountain scenery that confronted the Corps of Discovery more than two centuries ago. Surrounded by dense forests, alpine meadows, and sweeping ridgelines, the area offers hiking trails, interpretive exhibits, scenic drives, and opportunities to learn about both expedition history and Indigenous heritage. Nearby historic sites along the Lewis and Clark National Historic Trail further enrich the experience, making Lolo Pass an essential destination for travelers seeking a deeper understanding of western exploration and the dramatic landscapes of the Northern Rockies.
