    Loved it

    This is a gem by the Boston Harbor. Appreciated the breeze and great path. I took our dog on the Boston side and it was about 1.5 mi total down to the treatment plant & back. The small public parking lot was pretty packed but we got a spot.

    Highly Recommend!

    We took our 10 week old puppy walking here and she loved it! Very clean, paved and people kept their dogs on leash. We will definitely be back soon!

    A beautiful walk around Deer Island

    A great walk around Deer Island Waste treatment facility. This historic site was a prison in its early days. Views of the Harbor Islands and city skyline are spectacular. Don't miss this hidden gem in Winthrop.
