Merrimack River State Forest is a small state-owned forest along the Merrimack River in the Town of Boscawen, Merrimack County, New Hampshire. It is a state forest, not a state park: there is no day-use area, entrance station or fee schedule of the kind New Hampshire State Parks runs. The federal Protected Areas Database (PAD-US) maps it at 158 acres, owned by the state’s former Department of Resources and Economic Development, and lists public access as unknown.
We could not confirm trails, parking or a trailhead for this forest. The New Hampshire state forest pages that would answer that were not reachable when we checked. Before you go, ask the New Hampshire Division of Forests and Lands, which oversees state forests, whether and where you can enter.
