This is a part of Maine where lumber was once king. Every town and village along the route is replete with reminders of that heritage. The Leonard’s Mills Museum in Bradley, a reconstruction of a 19th-century sawmill, should not be missed. In addition, there are numerous opportunities for wildlife viewing along the way. The Bangor Historical Society publishes a guide for an architectural walking tour of the historic buildings in downtown Bangor. The 84-mile ride follows the Penobscot River from Bangor to Howland, before swinging west through woods and farmlands, and finally south through the agricultural fields of western Penobscot County. Old dams, mills, and farms dot the countryside, and there are many other points of interest.
