Really enjoyed this hike on a beautiful late August day. Took the public transport Bus #197 to and back, worked out just fine. I took the 7:30am bus from Port Authority which arrived at location around 9:30am, allowing for me to take the bus back at 4:20pm. Surprisingly rugged terrain (which included use of hands at several spots), thick vegetation and occasional lack of signs (the AT is pretty low-key and sometimes just seems to "vanish" in the bush) made for a hike that was tougher than expected, but also way more fun. I had a print-out of the description which proved very useful when in doubt.
The only issue I had with the description is that it doesn't mention that the AT meets a yellow-blazed trail shortly after the state line, but BEFORE meeting the blue-blazed State Line Trail. Some, like me, might mistake this for the yellow trail mentioned further on in the description, which led me to believe that I had missed the turn onto the blue State Line Trail. Just ignore that first yellow trail as well and keep going on the AT and the blue trail will eventually show up.
It took me about 5h30 to do the trail, which included at least 1h of breaks and enjoying the views, the track is definitely doable within 5h for a steady hiker. I also got to relax at Greenwood Lake and dip my feet in the water once done, that was a bonus. Highly recommend the trail for motivated hikers looking for a day trip.
