Governor Mountain is a 5.7 mile out and back trail located near Ringwood, NJ and is good for all skill levels. The trail is primarily used for hiking and is accessible year-round. Dogs are also able to use this trail.
Easy hike with outstanding views of Wanaque Reservoir Trail starts at Sloatsburg Rd. It's a pleasant, easy hike through a mixed hardood forest with ocassional stands of cedar. Two road crossings are involved (the roads aren't very busy). Upon reaching Governor Mtn, you begin a gentle ascent to the summit. From there you will see excellent views of the Wanaque Reservoir. The trail loops around and joins itself north of Governor Mtn. For shorter hikes you can also start at the crossings on Morris Avenue (knocks a mile off the hike), or Carletondale Rd (which reduces the hike to 2 miles RT).
The trail head is a little difficult you find but once you're on it, it's yellow the whole time. It was clearly marked and the summit has a beautiful view of the Wanaque Reservoir. It was a little longer than listed also. My map my hike put it closer to 8 miles.
