The Big Sky Trail provides some of the best backcountry snowmobiling in Montana. This 40-mile trail begins just north of West Yellowstone. The first portion is groomed, but the trail quickly turns into an un-groomed powder experience. The Big Sky Trail is not groomed as often
as other trails in the area. If you are in search of fresh powder, you may find it here. The trail begins from West Yellowstone and heads north along the western boundary of Yellowstone National Park. From West Yellowstone, there is seventeen miles of groomed trail followed by thirteen miles of 'un-groomed powder' until it reaches the Sunlight Basin Trail. About 9 miles out of town the trail crosses the highway and heads northwest. After the road crosses the highway, the area opens up into the Cabin and Tepee Creek area. This area has open bowls, deep powder, happy snowmobilers and a forest service cabin that can be rented. Though the scenery can be breathtaking, you will seldom see wildlife due to the immense powder and thick forest. Deep fields of snow, and outstanding hill climbing opportunities are the hallmark of this well-known and challenging trail. This is a trail for more aggressive riders looking for backcountry access. (Try Carrot Basin and Skyline Ridge.)
