About Old Mill State Park
1937 marks the founding of this small park along the Middle River, set on an ancient beach ridge formed by glacial Lake Agassiz. The river runs through the grounds between Argyle and Newfolden, in the northwestern part of the state. The park's name points to a milling history tied to the site, though the details of that operation are not spelled out.
Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
