This is a great loop hike. Its been some time since I had been to this area, and this hike makes for a great loop that is highly recommended and someone remote without the large crowds. We parked at the Ramapo-Dunderberg Trail trailhead parking on Route 9W, but the road bend, and climbed up the steep ascent of the Ramapo-Dunderberg Trail, passing the abandoned Dunderberg Spiral Railway several times and the tunnel near the beginning. We went around the bend and the first loop, as well as the eastern summit view of the mountain which has great views of the Bear Mountain Bridge. We then heading down through the notch on the mountain, and took the unmarked Bockberg Trail southwest, and then bushwacking to the Timp-Torne Trail at the view facing south. We then descended slowly and passed the unfinished tunnel, and then headed down along the trail to its end at the Ramapo-Dunderberg Trail, and then continued back down the mountain to the trailhead.
