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

Having ridden this trail in sections numerous times, and having ridden the entire length in a day last fall, It's my opinion that this is the finest rail trail for cycling purposes in NH.

In Merrimack county (Boscawen to Danbury) the dedication of the local friends group is evident. The trail is well maintained and the surface is excellent. From Grafton to Lebanon (Grafton county) the surface is trickier, with regular sandy spots and some exposed railroad ties. Despite this, the trail is still very ride-able in a gravel bike, and my wife had no issues in Merrimack county on a cruiser/townie bike.

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.

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.

started at the southern terminus at rte 63 North of Northfield Mass. and South of Hinsdale. The trail starts across rte 63 from the large parking lot, up on the berm. The trail is in poor condition at this point. The trail is not much more than a unused fire road. A better starting point would be the Hinsdale rail station. My highlight was the Ashuelot Covered Bridge. I returned to my car from that point.

I have found a nice way to link to the Windham Depot to Derry Trail. At the southern end, cross over Rockingham Road onto Seasons Lane and turn left onto Coteville Rd. At the end of Coteville there is a short path through the woods that comes out on Franklin St Ext. Follow Franklin and turn right onto Mitchell Ave. At the end of Mitchell is a path that goes to the Windham Depot.

It’s a nice short trail, and I don’t think many people know about it.
