Bradley Palmer State Park is a public recreation area covering on the Ipswich River in the towns of Hamilton and Topsfield, Massachusetts. The state park was once the estate of noted attorney Bradley Palmer. In addition to an extensive system of multi-use trails, the park features Palmer's restored Willowdale Mansion. The mansion is now home to Willowdale Estate, a premier event venue. Bordered on the north by the Ipswich River and Willowdale State Forest, the park is managed by the Department of Conservation and Recreation.
The park is the former estate of Bradley Palmer, an attorney of the early 20th century. Originally, the dense forest that composes the modern park would have been farmland, which Palmer both cultivated, and used to build his impressive steeplechase. During Palmer's lifetime, Palmer hosted regular horse races for the Myopia Hunt Club. Palmer was an active member in the Topsfield community, owning approximately 10,000 acres in Topsfield, Hamilton, and Wenham areas. Palmer often rode his favorite horse, Rifle, around the towns, smoking a cigar sticking straight out of a pipe. Near the end of his life (between 1937 until 1944), Palmer willed his lands "“to the people of Massachusetts as a place to enjoy the peace and beauty of river, woods, fields, and hills”.
The park features meadows where blueberries can be picked, equestrian runs, stands of climax white pine and hemlock, and a central paved road lined with white pine and in one stretch of a few hundred yards of rhododendron and mountain laurel thickets. On its northeast edge, the park has contiguous access to the ruins of Willowdale Mill, a former textile mill.
The park is used as the home field for meets of the Masconomet Regional High School cross-country team. In the autumn, the neighboring horse farms conduct fox hunts (they bring their own fox). Sometimes equestrian meets are held there. Numerous hurdles are in evidence in the equestrian runs, which are periodically mowed. Horses brought in by trailer at will may usually be seen on any non-winter day, more so toward the autumn.
