Established in 1915 and named after its benefactor, local furniture maker John Ainsworth Dunn (1831-1915), Dunn State Park is a 132-acre park, providing a wooded, pond-side experience close to an urban environment. Managed by the Massachusetts Department of Conservation and Recreation, the park includes a universally accessible family picnic area and beach, as well as two small playgrounds and exercise equipment spread along the trail system.

The 20-acre Dunn Pond has a curving coastline with many interesting views of coves and an island. Ducks, gulls, and turtles are often seen near the water and throughout the trails you might catch a glimpse of a chipmunks, squirrels, and birds. The pond is stocked twice yearly with trout and has numerous fishing piers, two that are fully wheelchair accessible.
