I'm in the park frequently but normally on shorter hikes that are closer to home. When I went to do Carpenter's Loop II a few days ago, Ross Dock was closed and there was a sign from Englewood Cliffs indicating the trail was closed. I looked at the map and realized I didn't have time to do the northern hike and I'd probably want at least a snack for that duration. It's about twice as long as Carpenter's II. I was able to get through Carpenter's but the next day I decided to finally tackle Clinton Point.
It was an incredible hike and Greenbrook Falls were pretty impressive.
