Belle Isle Marsh Reservation
This 300-acre patch of remaining wetland environment is indicative of the salt marsh landscape that covered Boston when early settlers arrived and which today has been filled in. As you walk or run Belle Isle's gravel paths, listen to the sound of the marsh's diverse bird community, which includes the American kestrel, belted kingfisher, great blue heron, northern harrier, and saltmarsh sparrow. Boardwalks venture into the marsh for great viewing and photo ops.
