Trail was pretty good. Very flat, met plenty of people with their dogs. Trails were a bit muddy in some spots but luckily the bridges have just been rebuilt so it wasn’t too bad. There was a couple of good size trees that were down once you go around the back loop. The area where the quarry is, was a little confusing because you can’t see the trail at all. We luckily used the map here to find the opening on the other side. Nice loop overall, wish someone would clean up the big trees that have fallen over though.

Great and easy loop for hiking or running. There are no major inclines, declines or rough patches. The Bridges have been repaired and going along the river for about 2-3miles is a joy.

I did this trail with my 7 year old son. Took us a little over 2 hours. There was no bugs when we went (Oct. 5). Beautiful and well shaded.

A nice trail, pretty good loop, did it with my 2 dogs they did great! Half the trail by the river was very challenging to get through because it was over grown. Definitely bring your bug spray as well! All and all a good walk!

Trail was pretty dry and a little overgrown on the backside of the loop. Looks like most of the bridges are slowly being replaced with new ones. Bring your bug repellent!

Easy, peaceful walk. However, there's a bridge out currently when you go to the left at the beginning of the loop, so you can't go around the loop. There's a lot of standing water, so wear bug spray.

Got cut off 3/4 of the way through because the trail was not maintained and too overgrown to pass. Beautiful river to hike next too though! Hope they do work to clear the trails out!

Awesome loop! Beautiful views along the banks of the Nashua. New bridge in one section and bridge out in another.

Despite the bugs and the fact that the bridges were out this might be one of my new favorite places to hike. It was a pretty trail and the dogs had a great time.
