In most counties, snowmobile trails will not open until after Dec. 15. Each county determines when to open trails, and many are waiting until the four day Dec. 11 though 15 statewide antlerless deer hunt is over. However, Dane County has opened snowmobile trails and some individual trail sections on state properties, such as the Kettle Moraine State Forest and some state trails are also open.
