Join members of the Groton Trails Committee and the Appalachian Mountain Club on a guided hike through the J. Harry Rich State Forest at 1 p.m. on Sunday, Jan. 12.

This 500-acre conservation area features low-lying woods and great views of the Nashua River, including where the river has shifted, leaving slow-flowing areas frequented by a diversity of wildlife.

The hike will take two hours. The hike is suitable for those with winter hiking experience in gentle terrain. Snowshoes are helpful if there is a deep snow pack. Dogs must be kept under owner's control and leashed upon request. The hike will be held unless it is stormy.

Take Route 119 west from Groton to Nod Road, found across from a retail garden store, at the Nashua River. Turn right onto Nod Road., which then bends, and proceed 0.6 miles east to the intersection of Common Street. Park there on the left.
