Bradley Palmer State Park is a public recreation area covering 736 acres (298 ha) on the Ipswich River in the towns of Hamilton and Topsfield, Massachusetts.

Bordered on the north by the Ipswich River and Willowdale State Forest, the park is managed by the Department of Conservation and Recreation.

Originally, the dense forest that composes the modern park would have been farmland, which Palmer both cultivated, and used to build his impressive steeplechase.

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”.

One-quarter mile east of the mansion consisted of a burn house, five story rappelling tower, shed class rooms and four collapse building simulators.

[citation needed] The park also offers picnicking,[11] canoeing, and fishing[12] in addition to handicapped-accessible wading pool and restrooms.
