Bay Circuit

The Bay Circuit Trail and Greenway or Bay Circuit is a Massachusetts rail trail and greenway connecting the outlying suburbs of Boston from Plum Island in Newburyport to Kingston Bay in Duxbury, a distance of .

Landmarks include Henry David Thoreau's Walden Pond, Great Meadows National Wildlife Refuge, the Charles River, Massachusetts Audubon's Moose Hill Wildlife Sanctuary, Minute Man National Historical Park, Lowell National Historic Park, the Merrimack River, and Plum Island.

The Bay Circuit Trail connects to other long distance recreation trails, such as the Warner Trail. The Minuteman Bikeway provides a connection to downtown Boston with the Somerville Community Path. The East Coast Greenway will also connect downtown if it is completed as envisioned.

The Bay Circuit is open to hiking, trail running and picnicking, and in the winter, snowshoeing. Certain parts of the trail are suitable for bicycling, horseback riding and cross country skiing. Swimming, mountain biking, hunting, fishing, and car top boating are also permitted in some properties the trail passes through.

The Bay Circuit Trail is overseen by the Bay Circuit Alliance, a coalition of state, town, and federal agencies, nonprofit organizations, and individuals. The Bay Circuit Alliance is led by the Appalachian Mountain Club which is working to implement the vision of the Bay Circuit by closing the final gaps of the trail, recruiting and organizing volunteers, improving the trail experience through improved maintenance and signage, securing permanent protection for the trail corridor and the greenway, and encouraging the public to get out and explore the trail’s 230+ miles.

Geography

The Bay Circuit forms a rough C-shaped arc between and north, west, and south of Boston. Although much of the trail follows a single route, several sections split in two and rejoin. The northern terminus of the trail is also divided: its northernmost section ends at Plum Island in Newburyport, and a southerly branch extends to the sea in the town of Ipswich.

The Bay Circuit passes through Plymouth County, Norfolk County, Middlesex County, eastern Worcester County, Bristol County and Essex County, Massachusetts.
