I had high hopes for this trail, based on the description. In reality, it falls far short! There are downed trees and overgrown brambles everywhere. The further in you go, the more trash you see. About midway on the trail, we started seeing tent sites with significant trash. Although we didn’t see any residents in the five or six encampments, its obvious they are lived in. There was no clearly marked exit from the trail and you have to wander across a parking lot or two to find your way back to the entrance.
The trail has a lot of potential, but needs some serious upkeep.

Parked in West Warwick next to rev dept tennis courts. Hopped on trail right there. Rode in direction toward Coventry. Interesting mix of residential, industrial, mills, rural areas. Clean, level and super fun.

My husband and I rode the Upper Charles Trail from the Hopkinton start to the near end in Holliston this last Saturday in November 2020. What a pleasant surprise! We enjoyed very pretty scenery in Hopkinton, a great lunch at Oliva's Market in Milford, visited the brand new Boston Honey Company store in Holliston, and marveled at the historic Phipps Railroad Tunnel under Highland Street. The trail changes from asphalt to very rideable stonedust in Holliston. At just over 13 miles one-way, the trail is a great way to enjoy being outside and getting some great exercise to boot! I thoroughly recommend this trail to anyone who likes pretty scenery, and great stops along the way.

Rode the eastern section of this trail from the parking lot at the end of Adams St in Uxbridge to Grove St in Franklin, approximately 11 miles. For the first 3.5 miles the trail is part of the Blackstone River Greenway and is in excellent condition with smooth blacktop surface. You'll see cyclists, skateboarders, runners and walkers on this section. The improved trail ends in Blackstone at Canal St. Follow Canal St downhill, make a left onto St Paul St, then right on Main St, and left into Castle Hill Way. The Southern New England Trunkline Trail (SNETT) resumes without markings at bend on Castle Hill Way. Surface now is packed dirt. Condition of trail worsens (sand, rocks, ballast) between Farm St and Center St in Bellingham. From Center St to Prospect St in Franklin, the dirt trail surface is groomed and in very good condition. The Prospect St bridge is now complete and the trail continues to Grove St in slightly rougher condition.

I definitely preferred this 11 mile Eastern section of the trail over the 12 mile Western section (in Part 1 of my earlier review).

I have done a couple of segments of the trail. One segment Starting in Franklin and going into Blackstone. Some parts of this trail were closed or almost impassible short of having a hardcore mountain bike not to mention that some segments are not marked at all. I have also done the segment from Rte. 98 in Douglass working east toward Blackstone there were segments that were in decent shape but there were others you can see that were rutted or still very wet given that we have been in a drought for a good chunk of the summer makes me concerned what they would be like if we had a normal amount of precipitation. Additionally, once I got near Rte. 146 the trail just seemed to disappear there were no markings to figure out where to go. Next time I will try and go from Douglass and work my way west and see how that goes. This trail has potential but needs a lot more work on it to be good.

Cycled approximately 12 miles of the trail from New Road in E Thompson, CT to RT 146 in Uxbridge, MA. The first few miles through the Douglas State Forest are in very good condition and patrolled by MA Dept of Conservation personnel. After that the trail begins to slowly deteriorate first with the surface becoming very sandy in places and then areas of ballast (large gravel) and standing water. The section from Chocolog Rd to RT 146 was challenging based on these surface conditions. You will need to look for a steep left turn down to RT 146 where singletrack runs alongside the roadway. Then watch for a steep right turn down onto Elmwood Road where the trail becomes interrupted for a short distance. To continue on the SNETT, make a left on Elmwood Rd to go under RT 146, then right onto Balm of Life Spring Road, right onto RT 146A, left onto Providence St, and finally left onto Adams St where it's possible to pickup the trail again continuing East.

The Air Line State Park Trail is one of my favorite bike trails in Connecticut. Rode our bikes there last week and was very disappointed with the recently resurfaced section from the Cranberry Bog in East Hampton. The gravel that was used in the resurfacing is to soft and to deep. Has only been open for a week (10/28/2020) and it is already marred by craters from horses and foot traffic. The ride is bumpy like a wash board. At one point I swerved to miss a pile of horse droppings and got to close to the edge which then collapsed under my bike causing me to fall. What was once a favorite section of the trail for us, is now a major disappointment.

We parked by the pet store mentioned in a previous review and biked to just passed the covered bridge, maybe 6 miles out? Beginning of trail is rough but that ends quickly . Nice ride in the woods. Not much to see. It was a slight incline on the way out which made the return better. I wish there some benches along the way to take a break.

I started at the historic fort phoenix on green street admiring the different architecture of the homes. Ride was easy, not crowded, just a bit too short. But a pleasant surprise after talking with fellow bikers. At the end of the phoenix trail, take a right onto Mattapoisett neck road, 1/2 mile on left is a cove, picnic tables overlooking the harbor. Continuing on Mattapoisett neck road 1.5 miles into a cul de sac, on the right there is a wooded trail you can bike to the water with a view of Brandt island.
The only reason i gave it a 3 was because i like a longer bike trail
