This Royal River Conservation Trust preserve has a Native American name: Mèmak, for pileated woodpecker. When I visited Mèmak in the winter, the preserve had a few snowmobile/ATV tracks cutting across it, and you could do an easy 1-mile loop through the mature woods, with oak, pine, hemlock, beech, and maple. The trail follows a mossy old stone wall for a ways.
Directions: The preserve is at 78 Lufkin Road, in North Yarmouth. There is a small parking lot on the left shortly before the power line.
