There are more than 25,000 miles of top-quality trails that link every corner of the state. The trails are well marked and methodically groomed by hundreds of snowmobile clubs. For a statewide view of major interconnected trails, the Wisconsin Department of Tourism produces a Snowmobile Trail Map. Using the standard State Highway Map as a subdued backdrop, this large fold-out map of Wisconsin shows the state's east-west and north-south Corridor Trails. Half the state is detailed on each side. It also includes trail contacts and snow condition phone numbers for each of the state's 72 counties.  Additionally, a Wisconsin Snow Conditions Report can be found on their website.

Local snowmobile clubs, chambers of commerce, tourism centers, or local governments may produce detailed maps of trails within local areas. The Snowmobile Trail Map includes listings of Community Tourist Centers (with telephone numbers) as well as state, federal, and county trail system contacts.  The Association of Wisconsin Snowmobile Clubs (AWSC) has trail information by county.  

Wisconsin has a program administered by the Department of Natural Resources and cooperating counties, funded from snowmobile license fees and gas taxes, to mark and maintain thousands of miles of trails. Much of the field work done under the program is handled by local snowmobile clubs.
