Sloatsburg Road not far from the NY State line; on your left if coming from the NY direction; very well signposted.
Ringwood Manor State Park has something to offer in all seasons. I did not "desaturate" the color in this photo; this was exactly how it looked.
This was a foggy day in December and there was snow on the ground. Look carefully and you'll see Ringwood Manor itself like a ghost in the background. This area of NJ is actually known for spooky stuff!
