The Stony Brook Conservation Area is made up of almost 400 acres of contiguous open space.  This property includes the East Boston Camps (EBC) known for its "Fresh Air Camp" that began in the 1930's for bringing inner-city children out to the country.  Today, the cabins, dining hall and grounds are rented out on weekends by individuals and groups during the spring and fall.  The Marcus Lewis Day Camp and Westford Parks and Recreation Department both run day camp programs during the summer months.  Even with the rentals and camp programs the trails and grounds are generally open to the public for passive recreation.

The Stony Brook River divides the property with the "Stepinski" parcels on the western side of the river.  Keyes Brook runs along the north-eastern boundary and the Veteran's Memorial Complex is north of the Mass Electric utility line.  Burges Pond, a clear water pond of approximately 25 acres and is surrounded by a network of trails including a 1.75-mile pond loop trail.  See links below for additional details about the Stony Brook Conservation land.
