The Upper Charles Trail is a planned 20 mile multi-use trail along an abandoned rail bed. It will travel through the towns of Milford, Hopkinton, Ashland, Sherborn and Holliston. Currently, the trail is complete in Milford and the rail bed has been partially developed in Holliston. In Hopkinton, a short section has been developed and is referred to as the Center Trail. The Hopkinton & Milford RR was constructed in 1871/72 to connect the Boston & Albany RR in Ashland to the Milford & Woonsocket RR in Milford. A total of four rail lines used to serve Milford. In 1898, the NY-New Haven & Hartford RR acquired this line, which was abandoned in1959. For more information visit; UPPER CHARLES TRAILMILFORD; UPPER CHARLES TRAIL & HOPKINTON; UPPER CHARLES TRAIL .

Upper Charles Trail; Hopkinton Section:

Starting from the Claflin Pl parking lot in Hopkinton [Northern End]; The trailhead begins off Main St. You'll find a Map Board here. 

Note; You can check out the old Hopkinton RR Depot, which used to sit across Main St near the lumber store, by heading left (west) down Main St (sidewalk available). After a 1/4 mile, past Whalen Rd, the sidewalk becomes a paved trail and levels out. After 0.5 miles, spot the old Hopkinton RR Depot (1872) next to Golden Pond. Pass by an entrance for the Berry Acres Conservation Area before the trail reverts to narrow sidewalk at 0.7 miles. Picnic tables located by the pond and RR Station. 

The Upper Charles Trail (Also referred to as the Center Trail) heads South from Main St along the old rail bed. This wooded corridor consists of a crushed gravel surface. A high berm soon leads to several informational signs about the old RR. The first sign points to an old wooden Whistle Stop post on your left. You cross a couple of wooden bridges before the trail leaves the old rail bed and heads slightly uphill. You come to Loop Rd at 0.6 miles. As the name applies, Loop Rd circles past the Hopkinton schools. 

Note; Here will be the future Campus Trail Connector, which will connect the Hopkinton High School, Middle School, and Marathon Elementary School. Funded in 2020.

Follow the narrow paved trail right alongside Loop Rd, crossing a wooden bridge, before coming to Lot x/Fields 12 & 13 at 0.9 miles. Bear right through the parking lot to the crushed gravel trail as it takes you left past the ball fields and back into the woods. Yellow circles mark the route. The trail currently ends after 1.2 miles at Chamberlain St.

Upper Charles Trail; Milford Section:

Starting from the Route 85 parking lot in Milford [Northern End]; The paved Upper Charles Trail heads South from the parking lot. You'll find a Map Board here. 

Note; Future plans call for continuing the trail North through Hopkinton. The old rail bed continues on the western side of Route 85 and crosses into Hopkinton almost immediately. 

Traveling through the woods, there appears to be a second rail bed or old road on your left paralleling this trail? When you come to a wide grassy area on the right with four boulders at the edges, just past a black access gate, this is where an old rail siding began. It runs past the two large boulders on the left and parallels the trail. At 0.5 miles you'll see a row of granite piers that used to support the elevated RR siding, which was built in 1897 and used to provide access to a nearby quarry. Just before Route 85 spot an old cement Whistle marker used by the RR to denote a crossing coming up. After a mile an automatic cross-light takes you over Route 85 where you'll cross a small bridge over the Upper Charles River, travel past Wildcat Pond and return alongside Route 85 at 1.5 miles. Use Caution when crossing in front of the I-495 on-ramp, as well as, the off-ramp after you travel underneath the highway. The trail then heads down away from Route 85 and comes to an intersection.

Note; Left follows an old road bed to Old Cedar St which will bring you back out to Route 85. Places to eat and restock are located here.

After a hairpin turn the trail heads up a slight incline. Just before a large stone abutment on the right and a granite bench on the left will be a dirt road at 2 miles. From the trail, take 32 paces (2 steps = 1 pace) down the road, just past a moss covered boulder poking into the road and next to a dead tree and stump off the right side of the road. Look to the left side of road and spot a stone wall between the gap of large trees. Go to the tallest section in stone wall (there should be a marble or quartz type rock on the very top). Go to the backside of the wall and remove only one flat rock that is leaning against the wall. Behind this rock is the Upper Charles Trail Letterbox

The trail winds through open woods, which are full of rocks and boulders and past granite and stone benches. A 2.6 miles you pass by a spur trail that leads to apartments off of Shadowbrook Lane. The trail then travels alongside Louisa Lake before coming to Louisa Lake Park. Check out the black "bike" gate leading to the parking lot.

Check out the bike sculpture on your right as you travel through an industrial corridor along your right and Milford Pond along your left. At 3.4 miles you pass by another spur trail on your left.

Note; You can take a short side trip here along the Clark Island Loop Trail. Head left along the wide dirt road as it travels alongside Milford Pond before ending at the tip of the island at 0.2 miles. To return head right along the grassy area to a hard packed dirt trail that follows along the opposite side of the island and back to the trail after almost 0.5 miles.

There are two cross-lights over Main St. Use either one and continue straight down Beach St (side walk available). Take a quick left on Mt Pleasant St where you'll pick up the paved trail again on your left at 4.3 miles. The trail now travels Northeast along a residential corridor crossing Hayward St and coming to Veterans Memorial Dr after 4.9 miles. The trail follows this road out to Route 109.
