This section of the Great Divide Mountain Bike Route leads from Helena, Montana, to Colter Bay, Wyoming, by way of historic mining regions, the sprawling ranchlands of southwest Montana, and one of the crown jewels of our National Park System. In addition to a sampling of some of its finest backcountry, one of the state's largest cities is also encountered— Butte. Plan a layover day in this mining-history rich city. The route also passes through the Red Rock Lakes National Wildlife Refuge and incorporates the short, 75.9-mile section of the route claimed by Idaho. 13.2 of those Idaho miles 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 route then enters Wyoming, cutting between Yellowstone and Grand Teton national parks on the little-traveled Reclamation Road, also known as Ashton-Flagg Road and/or Grassy Lake Road.
