I was last here in the fall of 2014. You can see photos from that hike here.
Here is a map of my route, starting and ending at the upper right, and walking counter clockwise. The circuit is 4.4 miles, but with all of the little extra side trips, I hiked 6.7. And I had a fun several hours doing it. You can see that much of the route is on a very narrow strip of land.
Here are a few photos of my little day hike. My knee felt okay on the flat surface. However, at one point I clambered up on a large rock to get a view of a wet area to look for salamander eggs, and when I stepped down, bending my leg way back hurt a great deal. So I am worried about mountain hiking.
Some of the many animals that I saw were: great blue heron, an osprey (with a fish), a shoveler (I think that is what this large duck was), double crested cormorants, Canada geese, tufted titmouse, cardinal, black-capped chickadee, American coot.
There is lots of mature forest in this area along the river.
The swampy area near the river will likely dry out in a few months.
You don't want to touch this vine, unless you don't mind getting poison ivy.
This is a distant view of the bridge that allows this hike to be a circuit hike - instead of almost four miles one way, and then returning another four to get back.
