The trail is a dirt and stone flat trail that is very easy to walk and very wide (1 lane road wide). The Farnum Pike entrance begins along the Stillwater River that connects the Stillwater Reservoir to the Stillwater Pond.
You pass by the under arched bridge of the Washington Highway with a spot for fishing. Most of the trail is canopied by trees as you walk along the river. There are a few areas where you can get off the trail and walk down to the water for some nice views of the ponds and river. There is one area cut away for powerline crossover but other than that section, it is all surrounded by trees
There are 2 manmade dams between the Stillwater Pond and the Capron Pond. The Capron Pond dam at the Capron Rd entrance you can walk out on to (or at least there were no signs saying you couldn't)
There are some great views of the ponds that are surrounded by trees with a few homes but not many to spoil the views.
It is a very quiet walk and well maintained and easy for the elderly or children to walk on.
Just down the road on Farnum Pike is a Stillwater Reservoir Dam (also called Stump Pond) and another flat area to walk out on the grass and cement dam (road level not a big high dam) where you can fish and boat run by the RI fish and wildlife dept.
Down a ways near the Smithfield Police Dept on RI 116 is the Smithfield Conservation Commission which has trails that can be walked along the reservoir (though they are hiking trails not flat trails) and even has an area for handicap access for fishing or to sit along the reservoir.
Overall it is a very nice area to visit, there are about 4-5 parking spaces at each enterance but plenty of parking at the Stump Pond Fishing/Boating area down the road. I will go back in the fall to see the foliage.
