The Big Sky Trail

The Big Sky Trail provides some of the best backcountry snowmobiling in Montana. This challenging 110-mile trail begins just north of West Yellowstone. While the first portion is groomed, the trail quickly turns into an un-groomed powder experience. This area has open bowls, deep fields of snow, and outstanding hill climbing opportunities.
