About Parsons Marsh
Parsons Marsh is part of the Undermountain Valley, a wetland and forest area in the heart of Lenox. Berkshire Natural Resources Council, the Town of Lenox, and private landowners have partnered to conserve this land for farmland soils, wildlife habitat, and recreation. BNRC’s 183 acres now offer an accessible trail that is half hard-packed surface and half boardwalk, encouraging all visitors to enjoy the wetlands and woodlands, and observe the abundance of plants and animals.

This land, and all of the present-day Berkshires, are the ancestral homeland of the Mohican people who were forcefully displaced to Wisconsin by European colonization. These lands continue to be of great significance to the Stockbridge-Munsee Mohican Nation today.

Parsons Marsh takes its name from John E. Parsons, a New York City attorney who purchased land in 1875 on the west side of Under Mountain Road and built a Gilded Age house and outbuildings. The original house was razed but the barn still stands as part of Stonover Farm. After Parsons’ death, his daughter Mary Parsons donated a large parcel north of Reservoir Road to Mass Audubon, which became the heart of the Pleasant Valley Wildlife Sanctuary.

Parsons’ daughter Elsie married John Drummond Kennedy who, after her death, in 1974 donated 84 acres at the southern end of the marsh to Lenox in her memory and in honor of her father. Kennedy also advocated having Lenox buy the land formerly owned by the Aspinwall Hotel after it had burned down. Lenox named the park created by this acquisition Kennedy Park in his honor.

Starting in 2016, BNRC conserved 183 acres in the Undermountain Valley, buoyed by an outpouring of support. Today, BNRC’s Parsons Marsh Reserve and Trail is a natural gem, open and free for residents and visitors eager for an immersive experience in the outdoors.

With the marsh conserved, we are looking for opportunities to build additional trails, including future connections to Kennedy Park and downtown Lenox. Beautiful rock outcrops to the south will be a compelling destination for an extended trail system.

Pollinators abound at Parsons Marsh. Check out a planted habitat near the pond and a natural habitat with many native species early along the boardwalk. Look for amphibians by the pond, seek skunk cabbage in the wetland, and try to spot some of the 75 nesting bird species that have been identified in Parsons Marsh. This area is also home to white-tailed deer, eastern coyote, black bear, bobcat, and both red and gray fox. The marsh and surrounding water bodies also house beaver, mink, and otter.

The forest in the southern part of the conserved area is dominated by white pine but also includes such hardwoods as red maple, sugar maple, white ash, and black cherry. To the south, you’ll find large rock outcrops, remnants from the glaciers of 20,000 years ago.

On the 1,800-foot (.33 mile) accessible trail, you will wind through an open meadow to a small pond, then into forested upland and vegetated wetland. Rest on the bench or picnic on the accessible table near the pond. Just beyond the pond, the trail transitions to a boardwalk as it enters the forested wetland with a bench halfway. The trail ends at an observation platform and bench to enjoy the open views from the edge of the marsh.
