Great Falls Portage, Portage trail and National Historic Landmark in Great Falls, Montana.
The Great Falls Portage extends for 18 miles along the Missouri River, offering a route around five major waterfalls through Montana's varied terrain.
In 1805, the Lewis and Clark Expedition spent 31 days navigating this challenging portage route while transporting their boats and supplies around the Missouri River falls.
The trail represents a critical segment of the Lewis and Clark National Historic Trail, preserving the physical path of the Corps of Discovery's western expedition.
Visitors can access interpretive exhibits and parking areas at both the Lower and Upper Portage segments, with detailed information available at the Lewis and Clark Center.
Two sections of the original portage route remain undeveloped, including the final 2.5 miles from Mount Olivet Cemetery to the White Bear Islands area.
