Researched from this park's own sources. Nobody's walked it yet.
Read this bit out
Twice a day the sea pushes up this river and fills the marshes, and twice a day it slides back out again. Herons and egrets stand in the shallows waiting for fish. Long ago this was a working river. There was a chocolate mill upstream, and the granite for the Bunker Hill Monument came down to the Neponset on a railway pulled by horses, then went by ship to Charlestown. One of the parks along it was once a dump. Now the birds have come back, with Boston right there behind them.
One of your three free places, or the Explorer Pass. What that costs
