Assabet is a 5 mile or so paved trail in good shape. We started at 72 Jefferson St. in Marlborough, MA where there was plenty of parking spaces and a path to the trail. The Assabet is pretty much a city/suburb experience with a few road crossings that need to be executed with care. Just recently it has been joined in Hudson by the 7 mile spanking brand new Hudson to Sudbury Trail (part of the Mass Central Rail Trail system). Then, in Sudbury the Bruce Freeman trail joins making for all sorts of possibilities for some great rides. My wife and I plan next time to park in Sudbury at the spot where the Bruce Freeman and Hudson to Sudbury connect (there's parking near) and make our riding choices from there.
2.5 stars. Entered the trail a the far western end on Hancock Rd. near Skatutakee Lake. Biked eastward for several miles. Mixed surface (dirt, cinder, sand & forest floor). This trail is rough and best suited for fat-tire or full-suspension mountain bikes. You could do it with a gravel bike but be ready for a very bumpy ride. Partially buried track ties and roots cover roughly over a 3rd of this segment of the trail. The swamps and brook are absolutely beautiful. There are a few benches for a peaceful stop. The trail has a gentle decline most of the way so be prepared for the uphill on the return trip. Mostly shaded so sunscreen isn't needed but bug spray might be a good idea if stopping for prolonged periods. The bridges are beautiful & well maintained. The signage is discreet & informative. This is a wonderful all season trail that I plan to return to in foliage season. It has a lot of potential but in its current condition it has a LONG way to go to become a destination that will attract tourists & generate $$$ for the local economy.
0.8 miles of this trail now consists of crushed gravel
I parked at Lexington lot & took my atb after reading how rough the path is. Pleasantly surprised. I'll take my road bike next time.
As of June 1, 2026, the first half of this trail starting in Bedford, MA is nice, but due to construction, it stops about halfway - I believe somewhere in Lexington. You can choose to exit the trail and go onto Massachusetts Avenue to ride in the bike lane, but that involves riding right alongside traffic and can be very stressful and dangerous. My husband and I did this today and I don't think I will do this again. At any point, someone in a parked car adjacent to where you are riding can open up their door right into you. Also, the bike lane often shares a lane with cars and is pretty scary for people not used to this. I hope the rest of the Minuteman bike path opens up to bikers again soon!
There's another couple of miles of mostly paved trail that goes beyond the parking lot in Lebanon. That's an excellent section of the trail. It took us all the way to Glen Road in West Lebanon.
I started in Acton and went up to Chelmsford. Plenty of parking and clean bathrooms—bonus! I really enjoyed this trail and look forward to doing the southern half soon.
I parked at the Delta Dental stadium and proceeded south in this trail. I was alone. I saw some unhoused people’s tents by the water. At first I felt fine, I saw another woman walking her dog, but there wee very few people on the path. The a person passed me on a bike and then circled back to me, following me. I felt unsafe. I wanted to keep going, but it was clear to me this person would following me. I had to quickly retreat to my car. I don’t usually feel vulnerable, and I was terrified. Later I told a local friend about my experience and she told me that recently a person had abandoned their baby on this trail, aka it’s not a safe place to walk by yourself, especially as a wow man.
Lot's of stops along the way to enjoy the sites. It's a very well maintained small trail
I'd ridden this trail a couple years ago, doing it in small sections, and had found it to be a nice ride with a decent surface, quite reasonable for my older hybrid. I only did about 6 miles today, from Keene southward before turning back, and those couple of detours noted in another review are still in place - taking you out onto the road for short stretches likely to avoid power line work being done.
