This recent edition of AMC Outdoors lists 6 parts of the AT that are good for snowshoeing. The recommended hikes (all day hikes per the article) are:
1. Maine - Piazza Rock and Saddleback from Rt. 4
2. New Hampshire - Lonesome Lake loop from Baisin Parking area
3. New Hampshire - Mt. Moosilauke from the west (thankfully)
4. Vermont - Spruce Peak
5. New York - Harriman Park
6. New Jersey - Delaware Water Gap NRA around Mohican Outdoor Center
I hiked in snowshoes for the first time in my life on New Year's Day and really enjoyed it. Looking forward to more!
