"Hello folks, I was visiting this trail on my way to the Dover Train Station to head back home to Danbury, CT as I used to live in Flanders, NJ.
You can access the trail by turning off of 46 East onto South Main Street in Wharton. It eventually becomes Main Street and then North Main Street. The trail unofficially starts 4 or so blocks after becoming North Main Street at the intersection of North Main and Pine Street some 3/4 to 1 mile from Route 46.
There will be a restaurant on the left called ""The Canal House"" (the old Morris Canal is nearby) and the Green Tent Company on the right.
Adjacent to The Canal House you can see the railbed go off and up to the right and disappear into the brush. I didn't have time to explore that as i had to catch a bus. (It is assumed it crosses North Main and unofficially starts to the left of the Green Tent Company and is grass and gravel for 100-150 feet.)
It officially starts at the end of the gravel and past the entrance to the industrial commerce park at a sign that says ""80-98 North Main."" There is no official sign saying it's a rail trail development. It's paved and some of it is a concrete sidewalk and passes the front property of a senior citizens living complex. There are two nice covered bridges with one going over the NJ Transit tracks and another over a river. It's downhill the whole way.
It ends in a quiet part of Wharton where there is a road to your right but it's pretty industrial. Before the end on the right is a garbage can and park bench. If you sit on the bench, you see woods, but if you face the bench, there's a fence alongside it and an empty wasteland of a lot. Not a good sight.
The trail ends abruptly at a street (East Dewey Avenue in Wharton) and if you look across the street at the normal path of the rail line it continues into the woods but in its place is a fenced-in water company water main.
I didn't have time to look behind it.
Not a bad trail and it's quiet but too quick.
