Great Falls Portage

The Great Falls Portage is a trail in Montana running along the Missouri River that bypasses five major waterfalls through changing terrain. The route includes multiple segments with interpretive signs and parking areas for visitors to explore.

In 1805 the Lewis and Clark Expedition had to navigate around the falls, which took many days and tested their endurance. This passage became a turning point in their journey westward.

The path marks where the Lewis and Clark Expedition traveled and shows how early explorers pushed through difficult terrain. You can walk where the group carried their heavy boats and supplies across the land.

You can enter the trail at several locations with visitor information and parking at major segments. It helps to check terrain conditions and weather before you go.

Two sections of the original route remain undeveloped, showing what the path looked like for early travelers. The final portion stretches from an old cemetery to islands in the river.
