Helena to Valentine: Epic Road Trip Across the Great Plains

The drive from Helena, Montana to Valentine, Nebraska spans roughly 800 miles across the Great Plains, crossing the Missouri River and traversing landscapes shaped by glaciers and pioneers. This route, primarily along US-12 and US-83, offers a deep dive into the region's natural and cultural heritage. One notable fact: the route roughly parallels the historic Mullan Road, a military wagon route built in the 1850s connecting Fort Benton to Fort Walla Walla, but here you'll be tracing a path that also follows parts of the Lewis and Clark Trail.
