The Mercy Woods Preserve is a small wooded preserve with two primary hiking loops. Dogs are allowed, but must be leashed. The Mercy Loop is relatively easy hike on a wide trail with gently rolling hills. It is marked with a yellow blaze. At the southeastern tip of the loop you get a great view overlooking the forest and reservoir. The other primary trail is the blue blazed Ridge Trail. It is a more challenging hike along several steep ridges. The Ridge Trail has vistas at the southeast and northeast sections and great views.
