Great Divide Mountain Bike Route - 1: "Roosville, Montana - Polaris, Montana - 542 miles"

This section of the Great Divide Mountain Bike Route is entirely within Montana. The route begins at the border and quickly enters forested backcountry. It skirts the western border of Glacier National Park. The route goes through towns every 4-5 days for restocking supplies. You'll either be going over passes or riding through valleys enroute to the next climb, and it's considered the most challenging portion of the entire route. You'll go through historic mining regions lying between Seely Lake and Polaris, Montana. In addition to a sampling of some of its finest backcountry, two of the state's largest cities are encountered- Butte and Helena, the state capital. Fascinating historic sites beckon in both communities, so plan to lay over at least a day in each.
