Does the Montana Trail 406 exist on the ground? Has it been built?

Yes, it is currently possible to do a continuous thru-hike of the entire Montana Trail. In most cases, the paths that connect to form the Montana Trail existed on the ground long before the concept of the Montana Trail was first conceived. People thru-hike it each year, and that number will steadily grow. GPX data of the entire trail is available on this website and onX Map provides an APP option: onX Backcountry.

The trail route is subject to change and may be re-routed in response to fires, floods, and other conditions. For information on routing and trail conditions, visit our website or our Facebook page or text our office at (406) 781-9542.
