Try the following:
*The Thompson Dam, Thompson
*Mashamoquet Brook State Park on Rt 44, Pomfret
*The River Trail in Danielson off of Rt 12. Go to Rt 6, turn like you are going to Big Y, take your first right by the water treatment plant, and go to the end of that little street. You will see a parking lot on your right. There are two ball fields next to the lot. Walk in between them and you will see the trail. It is about 2.5 miles. Takes my friends and I approx. 1 1/2 hours to walk it. I like it there the best because the trail is paved and the river is calming to look at during all the seasons. The smell you smell is only in the air when you drive in and out. You don't smell it when you are walking.
Maybe I will see you there. Have fun.
