The Bay Circuit Trail begins and ends with a foot in the ocean.
The path in between travels 230 miles, from Bay Farm on Kingston Bay in Duxbury in the south to the beach at Plum Island in Newbury to the north.
The C-shaped path around Boston was first conceived in the late-1920s as part of a greenway belt through the region’s expanding suburbs, but took decades to come to life. It remains a living thing – growing and expanding as advocates in its many towns work to fill gaps in the original layout or connect sections through more attractive land.
