Willoughby State Forest, State forest in Caledonia County, Vermont.

Willoughby State Forest covers 7,682 acres across Newark, Sutton and Westmore in Caledonia and Orleans counties. Lake Willoughby bisects it, with Mount Hor rising 2,648 feet to the west and Mount Pisgah 2,751 feet to the east. Bald Mountain, at 3,315 feet, is the highest point in the forest.

The state established this forest area in the late 1920s as a protected woodland to preserve natural resources and provide recreation opportunities. This protection decision marked an early effort to set aside land for public use and environmental conservation.

The forest serves as a place where visitors come to connect with Vermont's natural environment and learn about the animals and plants that live here. People use the trails and lakeside areas to spend time outdoors and experience the rhythm of the seasons in this landscape.

The forest has marked trails of varying difficulty that start from different entry points and lead through different parts of the landscape. Parking areas are located at the main access points, making it easy to reach the trail network from different starting locations.

Willoughby State Forest holds two designated natural areas: the 950-acre Willoughby Cliffs Natural Area in Westmore and the 30-acre Marl Pond and Swamp Natural Area in Sutton. The forest also spans the divide between the Saint Lawrence and Connecticut River watersheds, and its highest point is Bald Mountain at 3,315 feet.
