Why are there dog walking restrictions in Southborough?

  1. Although we love our furry friends, no dogs are allowed on DCR property within the Sudbury Reservoir watershed. This applies to trails throughout town as noted on this page.
    1. Dog walking is permitted at the Town Forest, Breakneck Hill Conservation Land, and Beals Preserve in addition to other commmunity resources such as Callahan and Hopkinton State Park.
  2. The Sudbury reservoir serves as backup drinking water and strict regulations are in place to help keep the watershed and water clean and free of pollutants.
  3. “Pet waste poses a serious threat to water quality as it is full of bacteria and viruses that can be harmful to people and wildlife, and nutrients that can cause harmful algal blooms.” DCR Educational Flyer  
  4. “Dogs are fed processed foods or people food that results in an excess of nutrients in their waste and the environment. Wild animals on watershed property consume natural sources from the ecosystem and return nature to nature in their waste.” DCR Public Advisory  
  5. Thank you for doing your part to keep the land and water clean. Even when dog walking is allowed, please pack out the dog waste. The increased use in trails has resulted in more dog waste in the community. Bad for humans, bad for wildlife.

The 911 Loop Trail is a 1.2 mile loop located behind the 911 Memorial athletic field. The trail overlaps on an existing DCR access road until it veers off into the forest. The wooded trail is extremely quiet, mostly flat, and has amazing views of the reservoir.  Trail users can enjoy walking, trail running, snowshoeing, and cross-country skiing. Just off the main loop at the end of the access road, you can venture to Pine Point to enjoy fishing or picnicking. The path is marked by a yellow painted circle.

No motorized vehicles or dog walking. 

There is ample parking at the athletic field (be mindful of sporting events when parking may be limited). 

Aqueduct Trail Marker

Aqueduct Trail  911 Loop

The Aqueduct trail system extends from Clinton to Newton, MA. Thanks to the Massachusetts Water Resources Authority (MWRA) for partnering with local communities in the Metrowest to create more trails and enable connections to existing trail networks on inactive aqueducts. As of 2018, MWRA has permitted approximately 27 miles of Aqueduct Trails.

In Southborough, the Aqueduct trail overlaps the Sudbury Reservoir (SRT) and Boroughs Loop Trail (BLT) [3 trails in 1; see SRT map below]. If you're heading west on the SRT/BLT off Ward Road, along the open channel, the Aqueduct trail continues straight into Marlborough. The BLT veers left into the forest (toward Crane Swamp in Westborough) at the spillway. A granite marker denotes where the trails split.  

On the east side of Southborough, the trail continues along SRT/BLT until the Rt.30 causeway at Framingham Road, where the trail turns right and extends east over tAqueduct Connectorhe causeway. The SRT splits off from the other two trails at this intersection (head straight across Rt.30 to continue on the SRT).   The Aqueduct Trail and BLT continue east on Rt.30 until the path intersects with the Bay Circuit Trail Connector (across from Thomas St, Framingham; see below). At this juncture, the trail takes a sharp left off Rt.30 into the forest (there is a post that marks this intersection).

Once the BLT's Peninsula Trail is opened to the public, the Aqueduct trail (and BLT) will be rerouted off Rt.30 onto the Peninsula Trail. The Peninsula trail is roughly 1.6 miles near the Fayville Dam. This section of trail will connect to the BCT/BLT connector near Stony Brook Rd. This reroute will not only be a safer option for trail users, but also includes gorgeous views of the reservoir & the Fayville Dam. The trail overlaps an existing access road. The 10-12' wide path meanders through the forest on a hard packed surface with a .5 mile paved section. The trail is quiet and set back away from traffic which adds to the experience.   


The Aqueduct trail will eventually split off from the BCT and BLT connector, taking a sharp right and continuing east to connect with the Weston Aqueduct off Pine Hill Road and then into Framingham. The Trails Committee is working with MWRA to permit this section of trail. See red arrows on the map. We expect the trail to open in 2021 or 2022. 

Bay CircuitBay Circuit Trail

The Bay Circuit Trail (BCT) is a permanent recreation trail and greenway corridor extending through 34 towns in Eastern Massachusetts and linking parks and open spaces in fifty-seven Boston area communities - 200 miles from Plum Isalnd and Ipswich to the Duxbury/Kingson Shore.

The Southborough section of the Bay Circuit Trail connects from Oak Hill Road through the forest behind Staples office park and crosses over Rt. 9 and onto Rt. 30. The Bay Circuit Trail Connector, from Rt. 30 to Clemmons/Nichols St., was dBCTeveloped as a more direct route through the forest next to Stony Brook and the Fayville Dam that connects to Clemmons/Nichols St and bypasses having to walk along Rt. 30 and Pinehill Road. The connector opened in September 2020 (see below for more information). You can park along the shoulder of the road at the intersection of Nichols St. The Bay Circuit Trail is a beautiful section of trail that runs along the Sudbury Reservoir for about 2.25 miles until you reach Parmenter St. in Marlborough. The trail continues to connect to other trails in Callahan State Park. The trail is great for walking, trail running, snowshoeing, and cross-country skiing. No motorized vehicles or dog walking.

The Bay Circuit/Boroughs Loop Connector Trail is .7 miles wooded trail that can be accessed from the intersection of Clemmons and Nichols Street in Southborough (where there is parking available). The trail is located near the Sudbury Dam Historic District and includes stunning views of the reservoir, Fayville Dam, and Stony Brook. The section of trail joins two existing BCT/BLT segments, eliminating the need to walk along Pleasant Street (Rt.30), Pinehill Road, and Clemmons Street.  No dogs permitted on this section of trail. 

Thank you to the volunteers and partnering organizations who help make this trail possible: Trails Committee members (past and present), Bay Circuit Trail Work Group, community volunteers, Massachusetts Water Resources AuthorityMassachusetts Department of Recreation & Conservation, Southborough Recreation, and Framingham Parks & Recreation.  A special thanks to the former Trails Committee members for their vision and efforts putting the permit in place and laying the groundwork for this trail to be built. 

Boroughs Loop Trail

Beals Preserve   

Click on image to open map

The Elaine and Phillip Beals Preserve is nearly 60 acres of former farmland just south of Route 30/Main St in Southborough.  It is owned and managed SOLF Logoby the Southborough Open Land Foundation (SOLF), a private non-profit land trust.  The primary entrance to the preserve is at a kiosk along the open channel of the Wachusett Aqueduct.  From the kiosk there is a short loop trail (approx. 1/3 mile) that heads south up an old farm lane lined with beautiful stone walls.  Past the fields there is an intersection at the “Lone Wolf Trail” to the right and the “Riding Ring Trail” to the left.  The Lone Wolf Trail takes one up a short distance to the top of the Upper Meadow with a nice view to the north. Returning back to the farm lane and crossing onto the “Riding Ring Trail” takes one through a quiet, old pine forest that once was a totally open horse-riding ring. If one looks closely there are still remnants of fencing around the ring. After leaving the pine woods, the trail bears to the left and back down to the channel.Beals Path

If one wanted to visit a small “ice pond” dating back to when the land was a working farm continue up the farm lane a short distance until it is visible on the left, then return to the “Riding Ring Trail.

Parking is available at the corner of Rt.30 and Old Northboro Road (cross Rt.30, walk across field toward small bridge of open channel). You can see the kiosk from this location. 

Beals Preserve hosts the annual "Art on the Trails" event featuring art installations throughout the forest from June through September of the year. 

Boroughs Loop Trail

The Boroughs Loop Trail (BLT) Project will connect the hiking trail networks of Marlborough, Northborough, Southborough, and Westborough to create a regional trail that encourages the exploration, enjoyment, and protection of the Boroughs' natural resources. The Boroughs Loop Trail, a 33 mile loop, will showcase the region's natural beauty, provide ecological and economic health for the region, and promote a positive outdoor experience for all. In Southborough, the BLT overlaps the Sudbury Reservoir and Aqueduct Trail (3 trails in 1) until the Rt.30 causeway where it travels east. Approximately twenty-four miles of the trail are opened. A ribbon cutting celebration was held in October 2019 followed by a guided hike series in the four communities. No dogs are permitted on this trail in Southborough, except for the section of trail located in Beals Preserve.   

The Southborough Trails Committee is working to complete its part of this loop while continuing to collaborate with the respective trail committees of the other three towns. The section of the trail that requires additional permitting and agreements is called the "Peninsula Trail" and is located nBLT trail picear the Fayville Dam. The Committee is working with MWRA and DCR to put the agreements in place to gain access to the trail. If all goes as planned, the Committee expects the trail to open by 2021. Follow us on Facebook to get the status updates.

Breakneck Hill is a beautiful 90-acre property of rolling hills, grassy trails, and wide-open views. Their are fantastic views for picknicking, birdwatching, and photography. In the past couple years, a few trails have been rerouted. The current map shown here is outdated but is still a good aerial view of the property. An updated map will be available in 2021. Dogs are permitted, please pick up and carry out waste. Please also keep dogs on their leash to protect the grassland nesting birds and other trail users.  

The property is maintained by the Southborough Stewardship Committee who provides conservation-based stewardship of Breakneck Hill Farmthe land, balancing multiple conservation and passive recreational uses. The trails are available to the public for passive recreation and dog walking. In the winter, the trails can be used for snowshoeing, cross-country skiing, and off-trail recreation. No motorized vehicles are allowed. The stewards are also managing the land to encourage grassland birds, and pollinators including monarch butterfiles and bumblebees. Be(e) sure to check out the beecology & pollinator gardens! 

In 2021, a kestral nesting box was added, several eastern bluebird houses were replaced, and a new map/info kiosk will be installed thanks to an Eagle Scout project.

At Chestnut Hill Farm, you can trek through 131 acres, past fields and pastures framed by stone walls, and enjoy grassland bird watching under the wide-open sky. Designated  bird reserves allow for safe nesting habitat for Bobolinks, Eastern Meadowlarks, and other ground nesting species.  Loop trails take you through upland forests and along the edges of freshwater wetlands. Or, follow the gentle cart-path from the parking area through fields of hay, alfalfa, and vegetables into woods dominated by oak, red maple, and white pine to the covered embankment of the Hultman Aqueduct, which provides a backup route for Boston’s water supply from the Quabbin and Wachusett Reservoirs. One of the last working farms in the town of Southborough, Chestnut Hill Farm is a living tribute to the town’s rich agricultural past..

In 2006, townspeople in Southborough overwhelmingly voted to purchase a conservation restriction on the unprotected portions of Chestnut Hill Farm. It is thanks to this vision and to the generosity of the Beals family that The Trustees are able to take over the care and protection of this community treasure today.  goats at chestnut hill farm

In 2015, The Trustees began a Community Supported Agriculture (CSA) program at Chestnut Hill Farm, accompanied by educational and recreational opportunities for visitors.  A small, rustic seasonal farmstand is open to the public several days a week and features local honey from the farm’s beehives along with farm fresh vegetables and fruits.

Two miles of trails. Easy walking. Please remember that this is a working farm landscape. Please stay on marked trails and away from any equipment or livestock that you may see. Fences should be presumed to be electrified. Dog walking

The east end of the Sudbury Reservoir Trail (SRT) starts on Framingham Road, across from East Main Street. The trail extends approximately 5 miles west through town to the Westboro line. One to two cars can park on the shoulder of the road. The trail follows the water's edge and crosses over Rt. 30. It continues along the reservoir, parallel to White Bagley. There are many good fishing spots along the trail.

The trail follows White Bagley and crosses over to Partridge Hill Rd. and then back into the woods. This section of the runs along the reservoir and wooded until it opens up before Cordaville Rd. There is an interesting rock island with boulders that many who love to climb would enjoy. This is a perfect location for a picnic, fishing, or to leisurely watch a sunset overlooking the water.

The trail continues across Rt. 85/Cordaville, and Middle Rd., and heads to Parkerville Rd. Cross the road and then turn right to continue along the water towards Deerfoot Rd. This section of the trail overlooks the Burnett House and includes historical markers that provide information about the Burnett House and the early settlers of Southborough. The trail continues past Beals Preserve, crosses Lynbrook Rd (changes sides and crosses bridge as you head west), Rt. 30, and Northboro Road. Just after the 495 overpass, the trail veers left over a small arched bridge and continues along the open channel towards Walnut Hill or Sawink Farm Reservation. The Sudbury Reservoir Trail overlaps the Boroughs Loop and Aqueduct Trail (3-in-1 trail).

Parking can be found on the shoulder of the roads off Framingham Rd., Rt. 30 near the intersection, Partridge Hill Rd., Rt. 85 (Cordaville Rd.), Middle Rd., Parkerville Rd., Deerfoot Rd., Lynbrook Rd., Northboro Rd., and at the end of Ward Rd. 

Although we love our furry companions, no dogs are allowed on DCR property within the Sudbury Reservoir watershed.  The reservoir serves as backup drinking water and strict regulations are in place to help keep the watershed and water clean and free of pollutants. Thank you for your help to keep the land and water clean!

Sudbury Reservoir Background:SRT-BLT OldNorthboroRd
In 1878 a system of reservoirs was constructed to provide water supply by holding back the Sudbury river, to supplement the Lake Cochituate system in Natick. These new reservoirs were Sudbury, Whitehall, Hopkinton, Ashland, Stearns, Brackett, and Foss. In 1947 the Whitehall, Hopkinton, Ashland and Cochituate Reservoirs were turned into State Parks, and in 1976 the entire Sudbury System was officially reclassified as an emergency water supply. Today only the Sudbury Reservoir and Foss (Framingham Reservoir No. 3) are classified as a reserve drinking water supply. The DCR owns and manages 4,943 acres of land in the Sudbury Reservoir watershed system.

Southborough Town Forest

Click on image to download pdf

The Turenne Wildlife Habitat lies on the northwestern slopes of Oak Hill, one of a series of steep hills that lie along Southborough's boundaries with Hopkinton and Ashland. Pasture-land fills old photos of Oak Hill from the late 1800's and early 1900's.  Today, frequent multi-trunked oaks, some 80-100 year old, support the ideas that portions of the property also served as a wood lot. This 18-acre parcel of woodland is underlain with granite, whose outcrops are visible almost everywhere along the trails. 

The Southborough Town Forest, approximately 54.50 acres, is adjacent to Wildlife Habitat. The Town Forest offers a network of trails including the historic Bay Path Bird House TFtrail that connects Walnut Drive to Woodland Road. There is a pond with a wooden bench overlooking the water. A perfect spot to pause and observe wood ducks, listen to a frog symphony, or view other wildlife.  

The forest is relatively young, consisting of oak, hickory, american chestnut, black/gray/white birch, and white pine. The Town Forest is a great location for walking, trail running, dog walking, and snowshoeing. You may see turkeys, hawks, wood ducks, deer and various species of birds while you enjoy these trails. Click here to see the 2021 environmental art installation, educational materials, and fun-filled activities available to you thanks to the Stewardship Comittee and the efforts of a local resident/artist and candidate for a Master’s in Wildlife Conservation and Management, Kimberely Berry. 

The property is dog friendly. All dog waste must be packed out. The poop fairy is not real and will not retrieve the bags you leave behind. ALL trail users appreciate your efforts.


There is parking at a small trailhead off Walnut Drive suitable for 2-3 smaller cars. This trailhead can be accessed by driving down Walnut Drive and continuing straight where Walnut veers left. This dirt road doubles as a driveway, but if you continue past the house on your left you will arrive at the trailhead.

The trails can also be accessed from Woodland Road. There is room for 2-3 cars to park on the shoulder of Woodland Rd. Parking is also available for 2 cars at the end of Kidder Lane (paved spaces) with a small walk to the side trail with the granite post and wood stairs.Town Forest Side Trail
