The Piney Knoll Conservation Area, formerly the Marsh Island Nature Area, offers over three miles of trails on varied terrain and habitat with everything from riverside marsh and open fields to regenerating and mature forest stands.

An area known as "Piney Knoll" is a popular place to sit and rest while surrounded by towering pines. In the winter, the network is connected to the University of Maine cross-country ski network and is a favorite local ski spot.

Trail Tips

Travel and Camp on Durable Surfaces
Stick to established trails and campsites. If there's no trail, try to walk on rock, gravel, or snow and spread out so that your group doesn't create a trail.
