The Bay Circuit Trail or Bay Circuit is a Massachusetts recreational trail which, when complete, will form an arc through the outlying suburbs of Boston from Plum Island in Newburyport to Kingston Bay in Duxbury, a distance of 200 miles (320 km). 150 miles (240 km) of the trail were complete as of 2007. The trail, first proposed in 1929 and imagined as an outlying version of Boston's Emerald Necklace trail, spans fifty towns and cities and four counties.

The trail links together conservation land, nature sanctuaries, national historic parks, state parks, and other public green space. The diverse topography of the trail includes beaches, cranberry bogs, salt marshes, woodlands, cliffs, drumlins, lakes and reservoirs, river corridors, swamps, historic sites and ruins, museums, farmland, meadows, kettle ponds, and eskers. Highlights include Henry David Thoreau's Walden Pond, Great Meadows National Wildlife Refuge, the Charles River, Massachusetts Audubon's Moose Hill Sanctuary, Minuteman National Historic Park, Lowell National Historic Park, the Merrimack River, and Plum Island.

Portions of the Bay Circuit Trail conicide with three other long distance recreation trails, the East Coast Greenway, the Minuteman Bikeway, and the Warner Trail. The Bay Circuit is open to hiking, picnicking, and in the winter, snowshoeing. Certain parts of the trail are suitable for bicycling 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 managed by the Bay Circuit Alliance, a confederacy of state, town, and federal agencies, non-profit organizations, and individuals.

[edit] Geography

The Bay Circuit forms a rough "C" shaped arc between 15 miles (24 km) and 30 miles (48 km) 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 ending at Plum Island in Newburyport, with a southerly branch extending to the sea in the town of Ipswich.

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