As with many of these cultural and historical trails, this one is confusing. See, this area is called The Quinebaug and Shetucket Rivers Valley National Heritage Corridor” which is just a huge area of the state that isn’t super developed. A number of museums and historic houses dot the valley, which of course I’ll be visiting.
Please go to the website above, as the folks who are responsible for the Last Green Valley would prefer you learn about it at their site rather than mine. Fair enough.
