Bay Circuit Trail: Callahan State Park.

The Bay Circuit Trail meets it coming in from the north after passing through the Sudbury Valley Trustees parcel called the Welch Reservation.

If the Charles River and its grand Esplanade might be thought of as Boston's front porch, then the Neponset River might be seen as its enchanting back yard.

Unlike the Mystic and Charles, with their impoundments located at the river mouths, the damming of the Neponset happens a bit further upstream so it has a fairly extensive section in sync with tidewater rhythms.
