Groomed snowmobile trails routes are managed under cost share agreements between the Boise National Forest, the Idaho Department of Parks and Recreation and locally by Valley County, Boise County, Elmore County and the City of Stanley.  The routes are groomed according to snow conditions and available funding. 


The Idaho snowmobile program is funded through registration fees purchased by snowmobilers. On November 1 of each year, every snowmobile operated on private or public land must be registered. Registration fees are $32.50 for residents and non-residents and $62.50 for rental machines.  You must register through the Idaho Department of Parks and Recreation.


Popular snowmobiling areas within the Boise National Forest include trails near Lowman, Idaho City, Smiths Ferry and Cascade. Use of the Park and Ski areas for parking including Banner Ridge, Gold Fork and Whoop-Um-Up are included with the purchase of the registration, but snowmobilers are asked not to use the designated cross-county and snowshoe trails.


The Idaho Department of Parks and Recreation (IDPR), along with local county services, groom many miles of trails.  Check the IDPR website for registration and more information
