How long has the Montana Trail 406 been around?

The concept of the Montana Trail 406 originated along the Continental Divide. In 2017 Marty Bannon considered a Montana State route while riding the Great Divide Mountain Bike Route following a successful thru hike of the Continental Divide Trail. The first thru-hike, using multiple modes (hiking, canoeing and mountain bikes) was completed in 2022 by Carly and Fey, who proved the route.

The route continues to be refined as trails and routes change in response to topography changes, transportation infrastructure changes, and land management policies.
