The road in is all paved and conditions were great. I was following the WTA app driving navigation through Apple maps and it took me past the trail head where there were cars parked near the buildings. The GPS did take me to another trail head and perhaps it all connects but I didn't try it today.
The trail conditions were thick with mud, no joke - bring some high boots if you want to explore.
I had a hard time knowing if there was an established trail here. We could see the bridge over the water easy from the car with minimal foliage due to winter. From there, muddy/rain filled foot prints went in all directions and since it was our first time we were unsure we hit all of the sites in the area. Navigating through the mud and flowing streams was challenging but with boots, gaiters and rain gear (plus trekking poles) we had a good laugh and enjoyed it.
The area does have quite a bit of trash strewn about (mostly beer cans, empty bottles, and other misc trash) and lots of graffiti on the structures which is really too bad. Otherwise - interesting place to explore and reading about the history before hand.
