Great Divide Mountain Bike Route - 2: Polaris, Montana - South Pass City, Wyoming - 510 Miles

This section of the Great Divide Mountain Bike Route traverses the broad open spaces of southwest Montana, a part of the state that could easily be responsible for the nickname Big Sky Country. It also incorporates the short, 72-mile section of the route claimed by Idaho, 30 miles of which are on a rail-trail conversion following the route of the old Oregon Short Line, which was responsible for delivering turn-of-the-century tourists to Yellowstone National Park. The trail then enters Wyoming, cutting between Yellowstone and Grand Teton national parks on the little-traveled Ashton-Flagg Road. The second half of this section takes you through the wild and spectacular Teton country, and winds its way down to historic South Pass City, where thousands of Oregon Trail travelers crossed the Continental Divide.

ABOUT ADVENTURE CYCLING MAPS
Adventure Cycling maps are created by cyclists, for cyclists, and they are some of the best available for those in search of discovery and adventure in North America. The maps reflect the association's research as well as suggestions from thousands of cyclists who have explored the Adventure Cycling Route Network. Adventure Cycling develops the best cross-country, loop, coastal, and inland cycling routes available, with turn-by-turn directions, detailed navigational instructions for the tricky sections, and elevation profiles in the high country.

The maps are waterproof and designed to fit in a handlebar-bag window or jersey pocket.
