The Normans Kill Ravines Park's address is 70 Wright Lane in Delmar, off Adams Place near the Four Corners. It is home to a rough 3.5 mile mountain bike trail that traverses up and down several ridges and swampy areas and follows roughly 250 feet of the Normans Kill. You should plan on at least 1 1/2 hours to hike this trail, as many of the inner connections (shortcut) trails are overgrown and unmarked, while the outer trail is designated "one way" and blazed only in the clockwise fashion (north -> east -> south -> west -> south).
