Snowmobiling   The signs read "Welcome Snowmobilers" and you'll find them posted in nearly every snowmobiling town in Maine: along Route 201 in Jackman, Route 4 in Rangeley, Route 1 in Madawaska and next to Moosehead Lake in Greenville. Welcome to snowy months filled with events and festivals for sledders. January features the New England Ice Drags in Presque Isle, the Rangeley Snodeo, and the Ricky Craven Snowmobile Ride for Charity in Greenville. In February, visit the International Snowmobilers' Festival in the Saint John Valley, Fort Kent's Annual Mardi Gras, and winter celebrations in Caribou, Millinocket, Houlton and the Moosehead Lake Region. Snowmobile clubs host hill climbs, poker runs, ice drags, and radar runs all season long, and guests are always welcome. Welcome to 12,500 miles of snowmobile trails, 2,500 miles of which comprise the Interconnected Trail System (ITS) which allows uninterrupted travel throughout the state. Sled the Moosehead Trail, the Black Fly Loop, the perimeter road of Baxter State Park, and the wide-open trails of Aroostook County. Explore ten thousand miles of local trails leading to secluded, frozen, beautiful places that most people will never reach, on foot or by vehicle, at any other time of the year. Working with generous landowners, volunteers from the Maine Snowmobile Association (MSA), with the support of the Maine Department of Conservation, have developed the expansive network of signed and groomed trails that travel over privately owned land in every corner of the state. Club members are proud of the system of trails they have created over the past three decades, and it shows. For three consecutive years, Maine Snowmobile Association groomer operators from Jackman, Pittston Farm and Millinocket have been selected by Arctco as among the best in the nation. You can help to keep the trails open by staying on the marked trails, respecting the land, and supporting the local snowmobile clubs. Ride safely, and enjoy!
