Long enough ride roundtrip to give you a workout but not too much. Beautiful scenery, shaded forest, open ocean, sea breeze, Del’s Lemonade, old homes. Will definitely ride this one again with friends.

My family has used this trail many times using it for Short walks between 6 road intersections. I'ts about 7 miles long and has many wonderful sites it is nor a particularly old in it's de-commissioning The last regularly scheduled passenger train on this spur ran in July, 1933 after that it was used lightly for freight in some sections until the late 1950's The highlight is the Mason Town Quarry loop between Depot rd and Sandpit road
featuring an old abandoned Quarry adopted and preserved by Mason NH. The entire length in one direction can be walked within 5-7 hours a round trip jogging about the same.

It is evident that much work has been done to improve this Trail.
Still I see from a optical sense there may be some improvements made to beautify it. Cut brush from the rescue could be chipped. Small dead saplings and other dead wood that is growing in the original rail-bed footprint could be removed and chipped lending to a more serene authentic scene of the rail-bed.
At the end if the trail on Jaquith road nearest to rt. 137 Prior to the trestle is a very steep rise in the rail bed not easily climbed by vintage locomotive engines in my view I imagine a wooden ramped structure bringing this higher part of the rail-bed up to the top of the trestle.
I wonder if there are any old photos of this elevation transition and how it was accomplished. These pictures may be a nice touch to this section's bulletin board
All the trail is delightful and the 100 yr .old steel span bridge is a great undertaking. We loved the red Lobelia in full Bloom Aug. 2 into it's brook beneath. I love the Old R.R. ties left in place to give more of a R.R. feeling . The bench at the swamp in the first section is a nice touch.
All in all a high five rating despite I feel a bit more cosmetic work can greatly improve the feel of this great noble R.R.route

Great path with lots of shade. The surface is nice and smooth and well kept. For the mountain bikers there are some great off road trails as well. We go there to walk and bike often.

We rode this trail from Rt 85 parking lot to East Hampton and back on 8/1, about 20 total miles. We’ve always loved the Air Line…it has a varied feel as you proceed through the different town…the vast majority shaded, sections on a high ridge above a stream, two nice viaducts across what was once a trestle bridge, a section running through a nature preserve. There were a few sections a little rougher than others, and we observed a few places with protruding rocks that should really be removed (just keep your eye on the road), as well as some divots in the roadway, some caused by drainage. There are no major hills but you do have long gradual uphills like the one as you ride into East Hampton going west. But I think for most riders these will be small things in what, overall, is a great trail. Great to see many out on the trail on a sunny, warm day.

Really enjoyed the trail. Great views.. sun and shade . We will be back !

I did the trail with my husband and my kids. My 11 year old daughter and my 16 year old son. Easy path and nice views. You can find restrooms and ice cream around. We began in Bristol and finished at the conservatory area at Warren, because it was block for maintenance. We rode 10 miles round trip.

Overall, a great trail. But it is over 50 miles long so there are some better areas than others. The East Hampton to Rt. 2 is scenic but it is steeper than other areas and the gravel is looser in spots. The 12 mile stretch from Rt. 2 to Willimantic is perhaps the best section - scenic, well maintained, not too steep, and hard packed. I’ve only been on the Willimantic section once and it’s nothing special. North of Willimantic is good though there are a few stretches that are rougher than other areas - barely passable on a hybrid bike. The trail is narrow in many areas so you’ll have to ask walkers to move over. Most of the trail is under a tree canopy which helps keep you cooler on hot days.

We started north from the Ashuelot River Campground. North ride was much nicer than the southern ride. North trail nice and wide and obviously well taken care of. Going south, not so nice . Basically ends up being and old narrow and rough ride. Could be muddy, if raining. Be careful of an old iron, wood beam bridge. Many rotten boards and nail heads popped up. That was enough, we road back on the road.
