The 35.5-acre Menotomy Rocks Park offers long wooded trails, wide open fields and a three-acre pond for fishing. On the Jason Street end, the park has a long playing field; on the opposite side is a small woodchip playground with slides and swings.

The town allows fishing on the Menotomy Rocks Pond, and dogs are allowed in the park if kept on leash. The thickness of ice on the pond is not monitored during the winter, so ice skaters use it at their own risk. Swimming is prohibited.

The park is supported by the Friends of Menotomy Rocks. Organized teams must request a field permit from the Arlington Recreation Department by calling 781-316-3880 before using town fields.
