About the Bay Circuit Trail & Greenway

What is the Bay Circuit Trail & Greenway (BCT)?

The BCT is a 230+-mile long trail outside Boston where you can walk, hike, ride, ski, or just get some fresh air. The trail corridor is T-accessible and traverses Eastern Massachusetts’s beautiful natural landscapes

History

The idea for the Bay Circuit Trail & Greenway arose in 1929. Thereafter, the vision was proposed as an “outer Emerald Necklace,”— in other words, a greenbelt that would mirror the famous string of Frederick Law Olmsted-designed parks throughout Boston. Above all, the corridor would provide open space for the city’s fast-growing population. Eventually, over the next several decades, various public and private open spaces were established in the area between what is now Route 128 and Interstate 495. However, they failed to keep pace with commercial and residential development. Finally, interest in the project was renewed in the 1980s, and in 1990 the Bay Circuit Alliance (BCA) formed to make the trail and greenway a reality

The Alliance focused on linking segments of the trail to provide a place for recreation by adding more “pearls” to the “emerald necklace”. That work resulted in what we now call the BCT

About the Bay Circuit Trail

The trail and greenway is located close to 4 million people in Eastern Massachusetts, starting at the mouth of the Merrimack River and ending in Kingston Bay. The BCT, a close-to-home trail, offers a variety of recreation options including: walking, biking, snowshoeing, horseback riding and cross-country skiing. Many sections of the trail are accessible by the MBTA commuter rail and other public transit systems

Since 2012, the Appalachian Mountain Club (AMC) has led Bay Circuit Trail partners in the completion, enhancement of the trail, and also the long-term protection of this greenway. At present, more than 230 miles of multi-use, passive recreational trail have been dedicated, thanks to the contributions of hundreds of volunteers in 37 cooperating towns

Furthermore, the AMC guides local communities in establishing their portion of the Bay Circuit Trail through planning and technical assistance, route identification, land protection, trail management and construction. Our sustained contact with state and federal government representatives and agencies helps us promote the Bay Circuit concept and improve trail-wide issues

To fulfill the vision of the Bay Circuit, AMC has been working to close the final gaps of the trail. We are working to document varied uses on the trail, improve the recreational experience, secure permanent protection for the trail corridor, and encourage the public to explore the trail’s 230+ miles.
