The Boroughs Loop Trail connects the trail networks of Marlborough, Southborough, Westborough, and Northborough to create a 33-mile regional trail that encourages the exploration, enjoyment, and protection of the Boroughs' beauty and natural resources.

The Boroughs Loop Trail links wooded walking trails, bike paths, aqueduct trails, and sidewalks. Hikers, walkers, and runners are welcome on all parts of the trail. Some sections allow mountain biking and dog walking.

Several SVT-protected properties link to the Boroughs Loop Trail: Baiting Brook Meadow Farm CR, Beals Preserve CR, and Cedar Hill and Sawink Farm.

Printable/Downloadable Trail Maps

The map for this 33-mile trail is too large to print on a single sheet of paper (useful details would be lost). We’ve broken the map into four sections (see image below for the region covered by each section).

Click on each link to download a printable PDF for that section. Portions marked as "Future Link" are currently inaccessible.

  • Section 1, from Boundary Street in Marlborough/Northborough to Stevens Street in Marlborough
  • Section 2, from Poirier Drive in Marlborough to Parmenter Street in Marlborough
  • Section 3, from Parmenter Street in Marlborough to Main Street in Southborough
  • Section 4, from Deerfoot Road in Southborough to Boundary Street in Marlborough/Northborough
