DH Mike,
At Sugatloaf, there’s a decent amount of trails that are groomed. The network of trails is managed by 3 groups: Carrabassett Region NEMBA, Maine Huts and Trails, and Sugatloaf Outdoor Center (nordic trail system). So a lot of shared use trails mostly with XC skiers & snow shoes. You should note that not every trail is groomed, and only a fraction of the Sugatloaf nordic trails allow biking, but the other 2 trail systems are open to biking. If you are into skiing, the best bet is to parlay a alpine skiiing at Sugarloaf with fat biking as conditions can be so fickle with fat biking (and Sugarloaf is an awesome Mtn). Check out the websites for the 3 groups I mentioned for more info. And if you don’t make it in the winter come in summer or better yet in the fall, when the entire network of trails is wide open 100’s of miles of remote riding & great views! Shred it up!
