Groomed fat bike trails, passes and live grooming reports
Maine's groomed fat biking centers on the western mountains, where Carrabassett Valley, Rangeley and Bethel run Nordic and NEMBA-groomed networks with trail passes. Volunteer NEMBA chapters also groom singletrack near Bangor, Brunswick and the Midcoast when there's enough snow, so check each group's page before you go.
