Land OwnerNew Hampshire State Parks
This trail is divided by Spruce Pond Road. The southern part of the trail is fairly wide and can become rather muddy. This side of the trail does provide access to the foundation of an old mill and a few brook crossings. The northern
side of the trail leads to Smith Pond. This is a beautiful area with access to a lean-to.
Camping is prohibited at the lean-to. The trail north of campground road is a bit narrower. A great trail for cross-country skiing in the winter.
