Don't let the winter bite keep you inside: Maine offers some of the Northeast's premier ski slopes, including Sugarloaf, Sunday River, and Shawnee Peak. There are trails for skiers at all levels, and even non-skiers can find activities like ice-skating, snowshoeing, and hiking to keep them busy. For those who prefer to move by motor, the Pine Tree State has hundreds of miles of snowmobile trails—try the majestic networks of Rangeley and Jackman. If more leisurely activities are the goal, ice-fishing is growing in popularity and offers visitors a unique experience.
