Ashuwillticook Rail Trail

absolutely lovely

June, 2025 by sfrankovich

I rode this trail from the Northern tip south about 10 miles and back. It was very smooth pavement, a well marked trail and delightful views.

Ashuwillticook Rail Trail

A fantastic trail

June, 2025 by pjohnromeo

Rode it Friday. The views were beautiful, the trail was in great condition, and the road crossings were not a problem at all. I’ll definitely be riding this one again.

Assabet River Rail Trail

Great but discontinuous

June, 2025 by yw8km5gp4n

The Assabet River Rail Trail is varied and enjoyable. The tricky thing about it is that it exists as two disconnected sections, separated by 2 miles of fairly busy road that's only suitable for confident road warriors. And that's a shame because both sections are marvelous and have much to recommend them.

The northern section runs from South Acton, through Maynard, and barely into Stow. It passes right through downtown Maynard, where you can find some decent food options and a bike shop. Proceeding south, it turns into a wide, hard-packed dirt road, and then finally ends as a slightly rougher dirt path. You can also easily access the Assabet River Wildlife Refuge from here, which has miles of wonderful off-road bike paths.

The southern section starts in Hudson and passes through the eastern end of its downtown, where there are more services and some worthwhile shops, including a bike shop. As of 2025, this part also connects to a new 8-mile eastbound section of the Mass Central Rail Trail. But if you continue on the Assabet River Rail Trail, you'll climb up into Marlborough -- it's pretty consistently uphill as you head south, but it's good exercise and has at least one excellent view. The trail more or less ends in the center of Marlborough, near the library, and where there are a few more spots you can grab a bite or get a drink.

So although this one isn't a straight shot, it's easily the most pleasant way to tour these towns and see what they have to offer. I hope finish it some day, and make it a single continuous Acton-to-Marlborough trail it's meant to be.

Nashua River Rail Trail

Awesome exercise route

June, 2025 by yw8km5gp4n

The Nashua River Rail Trail is terrific. It's long, smooth, well-maintained, and beautiful. Since it lies in a relatively rural part of Massachusetts, I find it to be a lower-key ride than its eastern cousin, the Bruce Freeman Rail Trail, but still well-used. There's less to see and do along it, but that might be exactly what you're looking for. Wholeheartedly recommended.

Farmington Canal Heritage Trail

Completed through New Haven

June, 2025 by tswetts

I just rode the trail from Cheshire to New Haven Harbor. It gets confusing because of the lack of signage once you go under the Temple St Garage in New Haven. You get dumped out into a street and don't know where to go. The trail is on the road or sidewalk depending on what you prefer. Take a left onto Grove St. continue to the end and take a right onto Olive ST. Follow Olive St. to the end and pick up the trail again on Water St. Cross Brewery ST and take a right to continue on Brewery. Brewery changes to Sargent Drive. Take a left to go under I95 and the water will be in front of you. If you take a right and continue down for a little, along the water's edge, you will find dozens of food trucks to buy lunch before a return trip. It was well worth the trip.

Canalside Rail Trail

Still Partially Closed

June, 2025 by gettinlate

As of 6/3/25 this trail is still closed south of 11th street.
There is a detour indicated, which we tried to follow, but quickly lost track of.
Found another way to access the trail further south, only to realize that we'd gotten onto the part of the trail that was officially closed.
I'm sure this will warrant a higher rating once it has re-opened, but we were more than a bit disappointed today.

Hop River State Park Trail

Great place for a ride, scenery, and history

May, 2025 by traillink.qmsck

I recently rode this on a cool day in May from Manchester to Willimantic and back, so right at 40 miles. The trail is well-maintained and foot/bike traffic was light, even though it was a holiday weekend. Very scenic for long stretches and low elevation gain. I rode a gravel bike with 45 mm tires. On a road bike with reasonable tires, this should be do-able (I saw a couple of them), but there is one rough section of about 100ft (30m) where you would need to walk. There is also one underpass that is dark enough to use a headlight...but it's passable if you slow down. There are a number of places to read about the history of the rail line, as well as a few locations with fix-it stations with bike tools and air pumps.
One final tip: Google maps takes you to an intersection on Colonial Road for the Manchester trailhead...the parking lot has a tiny sign that is easy to miss.

Southern New England Trunkline Trail

Correction

...we rode the western part... (is there a tool to edit a review?)

Southern New England Trunkline Trail

Partly very rough ride

May, 2025 by arno911

We rode the eastern part of the trail today, starting at the CT/MA border towards Douglas. The first 6-8 mls are well maintained and a good ride even with a street bike. Nice scenery, too. But then things get worse around Douglas. Rough surface with crushed stone, sand and deep puddles after a rainfall (like today). Looks like the track has not been maintained in a while and detoriates. A mountain bike is a big plus and highly recommended in some parts of the trail. Was a good ride though but do not expect a smooth one.

Blackstone River Greenway

Stanley Woolen Mill in Uxbridge going North to Church Street

May, 2025 by andrix

This is described as a 3.5 mile section but we only went about half way to the dam from the Stanley Mill. It is passable on bikes but has roots and larger stones along the stone path. It's really more a walking trail. The farm mentioned in the description was an interesting side visit and had very nice bath & water facilities. However, for a great biking experience the 10 mile section starting at Woonsocket is paved and a far more pleasant ride.

Assabet River Rail Trail

glorious

May, 2025 by robertschless60

Just rode the trail south to the Sudbury line. The east west trail is finished to the west for another 8 miles. It connects to the Hudson Trail at the end.

Moosup Valley State Park Trail

Great Little Trail!

April, 2025 by 9q8skpdwwc

I rode the Moosup Valley Rail Trail a few days ago from Moosup to Oneco. The trail is in excellent condition all the way, and beautiful! I rode 34mm knobbies, but would have had no trouble on 28 slicks. The only irritants were a guy on a motorized scooter in Moosup and 2 guys on screaming dirt bikes going the other way a bit farther along, but they passed quickly. In Sterling, dirt bikers had dug shallow ruts into a short stretch of path, diagonal to direction of travel, which made it bumpy but not hazardous. Otherwise lovely! I wish Rhode Island would step up to the plate and finish the connector to its Washington Secondary path.
