Parked at the northern terminus of the 4 Birds Trail. There was just enough space for one car since there is new construction at this site. The Fall views are nice. Took a woods road off 4 Birds and then bush wacked a short distance following my hiking GPS.
Took the white-blazed Four Birds trail from Greenpond Rd. Although it's shorter coming down from Bigelow Rd, it was a nice day and I had never been on this section of Four Birds. Parked at the little pulloff along the road (41.030127, -74.453980). The trail is easy, beautifully maintained, and well marked. Thank you NYNJTC. It's about 2.3 mi to Mt. Newfoundland. There are some lovely views to the east along the way. As the trail passes near the summit, there is an ATV track that branches off to the left (41.042545, -743457469) and goes within 100 feet of the summit. Not much to see at the summit.
I had planned to continue on to Greenpond Mountain but ran out of time and so just returned the way I had come. Along the way an NSA surveillance drone disguised as a turkey vulture flew very close overhead checking me out. Very realistic.
