Snowmobiling on the Custer Gallatin National Forest

All across the forest, one can find opportunities for snowmobile recreation ranging from groomed trails to challening backcounty terrain. 


West Yellowstone Area Snowmobile Trails

Snowmobile trails in the West Yellowstone area are open December 1 through March 31. More than 135 miles of professionally groomed trails start both south of Electric Street and west of Iris Street, and also north of Dunraven Street in West Yellowstone, Montana. The high elevation allows for plenty of snow, and the trails range from flat to mountain climbing.

The speed limit on all groomed Forest Service trails is 45 MPH. Snowmobilers must stay on designated trails while traveling through the restricted area. All litter must be packed out. The trails have two-way traffic, so riders must be aware of oncoming traffic and keep to the right. No drinking and driving is permitted. Riders must also be aware that moose, elk, and bison may be on the trails. All snowmobiles must be registered.
