Black Rock Waterfall near New York/ New Jersey Border

Black Rock Mineral Springs hiking trail! As I left northern New Jersey and headed North, I bumped into a road off of a country road, where there was a beautiful waterfall in a forest .... and you could swim in the pool of water at the bottom of the waterfall. The road was called old mineral Springs and I believe it was off highway 17... After you park, Walk up a mild incline and then down a bit it's only a 3 to 5 minute walk to this particular waterfall.
