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 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.

Go biking here quite often a lot of shade good when it's hot

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.

We had a great time on this flat trail, which does have some old railroad tires and nails popping up along the way. Using “Map My Walk” it was 7.12 miles from the parking lot to the falls and back. The falls are very refreshing, with a few safe still pools to cool off in! Highly recommend this trail! You can also visit other side trails off this one, including Black Pond which we do next time!

I will preface this by saying I'm basing my opinion on being a runner. It is probably a great trail for dirt bike riders, ATV riders, snowmobilers, etc. For runners the surface is soft in places, pitted in places, has lots of rocks in places, and overall is just not a great surface for runners.

We rode much of the trail on a tour from the MA/NH line area north of Winchendon, MA to Keene, NH. It's a beautiful, relatively flat route with some great views though high water source areas, ponds and some views of Mt Manodnock then descends along the river into Keene. We were on semi-loaded touring bikes, so jumped off on roads when they paralleled the trail since the surface is a little bumpy. Hybrid or MTB's (as recommend) would be more comfortable, but for those on touring bikes, the direct route through some road less areas is well worth it.

First of all, Peterborough is a lovely little town to bike in and around. The trail was shaded, clean and paved all but 1 mile or maybe a little more. We parked in the shopping center parking lot and then followed the well marked signs along some town roads before getting on the bike path. Beyond the parking lot on the north end, the cinder path continues. We bikes for a while before deciding to turn around.
