Some of the most interesting adventures at a convention take place outside the convention center. In addition to the canal and trolley rides, the Lowell National Park offers many other interactive exhibits of New England industrial archeology. Or enjoy a visit to a prototype rail facility not normally open to visitors. We are fortunate to hold Mill City 2020 in one of the most beautiful and historic areas of Massachusetts during what is traditionally the height of the autumn foliage season. Please plan on extending your stay for additional exploration. Please check back since these pages are updated frequently.
