Almost every parcel in Groton is a good place to cross country ski (or snowshoe), but the areas described below are extensive and support long excursions into the white wilderness.
Groton Town Forest
The Groton Town Forest has everything for the Cross Country skier. There are over 15 miles of trails to explore from some white-knuckle schussing, to mostly flat. There are many hills and adventures for those who are brave enough, but there are also easy going flat loops. The central part of the Town Forest is a flat glacier river delta, but it drops off sharply along rivers on the Eastern (Nashua River) and Southern (Squannacook River) borders. There are also a multitude of kettle holes and kettle ponds in the central area that make striking exceptions to the generally flat terrain.
Signs for the Town Forest on West Main Street (Rte. 225) will guide you to Wharton Row. When you get to the stop sign at Town Forest Road, turn right and the parking lot is just inside the woods. If it is not plowed yet, park responsibly on Wharton Row. Have an amazing time on this wonderful property.
