I tried to do this hike from the ATV trail that intersects Mud Pond Trail, but no one answered the intercom to let me in the gate. So instead, I drove to the parking lot at the end of Sand Pond Road and started from there. About a 1/4 mile south of the parking lot, a woods road crosses Sand Pond Road. This trail is not on the NYNJTC map but it does turn into the TC trail that dead-ends south of Lake Wildwood.
So I bushwhacked, crossing the Lake Wildwood stream (easy), until I stumbled upon the woods road. From there, it was an easy walk to within a couple hundred yards of the high point. A cairn marks the spot. No view from the summit, but it was a nice, quiet walk in the woods.
