Galloping Hill Park and Golf Course.
Kenilworth boro, Union County, NJ

Located in the southwest section of the intersection of Garden State Parkway and Route 22, when we visited (November 29, 2003) it appeared to be just all golf course and no park.  There are warnings that if you do not have a green day ticket you could receive a $20 dollar fine for trespassing.

Directions:

Get off the Garden State Parkway at exit 138.  Drive west for a short ways.  The golf course is not far away on the right.  

Trails:

Are there any? 

Unfortunately, there are no trails connecting to Black Brook Park, Lenape Park and Nomahegan Park.  Union County should get to work on this.
