Went from Keene to Troy Depot, passable, but very rocky, muddy and barely passable with a hybrid bike. Finding the trail out of Keene wasn't obvious - finding and following the blue diamonds on the trees helped. Crossing rte 101 is pretty dangerous. Toward Troy, there's a lot of what appears to be snowmobile trail maintenance going on making the trail difficult for biking, again dislodged rocks and lots of mud. Left Troy going to Fitzwilliam and the trail became unpassable with my wife's hybrid and difficult on my mountain e-bike. Big time wash-out on the trail that goes on forever. I recommend staying away from it at least this time of the year unless you like this kind of mountain biking...

Not bad. Started in Franklin. Tilton not that bad. Need to use street for a bit, stay on north side of Rt 3 in sidewalk. Ends at a McDonalds and Super 8 ( not motel 6). Good ride, too short

What a great trail! I agree with one of the other reviews. That the trail is mostly uphill if you start from the Flume; coming back the other way is exhilarating! A couple of tough uphills, but they are short. The views are amazing. One tip: you can get going very fast downhill, but the trail is a bit bumpy so watch your speed, particularly if the trail is wet.

Once we got to the Sanitation site north of Keene the trail wasn't more then a goat trail. Muddy, rocky narrow, and not very much fun. We turned around. Maybe it would be better from Walpole south.

This was moderate to difficult. But I am in my advanced 50s and over weight. It is 85% uphill, a lot of rocks. Not sure if all the rocks are from hurricane Irene or if it has always been rocky. A hiking stick was helpful for balance. My husband, same age, not over weight found it moderate to difficult, but navigated the rocks much more easily. The falls are incredible! Worth the hike.

I live about 7 miles from the South Londonderry trail head and only wish the trail was better suited for my hybrid bike. The first 3 miles (approx) to the Winhall campground are in bad shape (dirt festooned with rocks, roots, ruts and mud puddles). I don't know when the article summary was written, but I have a different idea of what "well maintained" means. Those with mountain bikes or fat tire bikes should have a much easier time with it though.
The trail ride is sandwiched by a campground road for a couple of miles. It's asphalt, and other than navigating several speed bumps, is an easy ride to another dirt path on the Jamaica side. It's in better shape than the South Londonderry portion. It's not in great shape for riding either but very manageable.
The two dirt path portions follow the contour of the tree lined West River. The view is particularly vivid, particularly in Autumn, and a favorite spot to hike with my dog. As a bike trail though, it needs work.

This trail is a lot of fun! Mountain bike is the best! Lots of railroad stuff to see!!!

The trail was in good shape. Unfortunately there wasn't much to see. The highlight was the trestle over the Sugar River. The place where the trail 'parallels Washington Street' was busy and care was needed because many cars were entering the shopping area.

Since the trail was short, we continued on the Sugar River trail. There was a fair amount of working being done on it and it was not as nice as it was one year ago. Sand was being added in places which made it more difficult to ride through. Overall, however, we'd recommend the Sugar River trail west side and make sure you see at least one of the two train covered bridges!

With touring version of an e-bike, found this trail to be interesting, historic, and fun! Yes, there are some spots with sand, but if one rides smart, no issue. Did not run into any of the ATV’s mentioned in the other reviews. Loved all of the River crossings, as well as the two covered bridges! Loved the white tailed deer seen on the route as well!
