I clearly did something wrong I used gps and this app to get there which lead to a parking lot. There were signs that said wear orange (like for hunters) it was a super short climb up big rocks to a super cool view but not this long hike everyone else is talking about.

for a shorter 4 mile hike with beautiful views, park in the lot off 248, make a right onto the white blazed Appalachian trail, follow that up the mountain, you'll get to the top with beautiful views. you'll follow the white markers to the backside of the mountain, eventually you'll enter the trees on a dirt section of the trail, stay on that for about 1/4 mile, you'll see a fenced in area on your right, make a left on to the winter trail (blue blazed markers)(you'll see a sign that says (winter trail, and explains that part of the app trail has been rerouted) follow that down the mountain, there are several areas that the path looks like it splits, just stay to your left and look for the blue markers. eventually you'll see the highway and come down to a path that walks along the roadway you can turn right or left, turn left back to the parking lot. you'll see huge fences on your left that keep rocks from falling, and there's an area that's really swampy when it rains, people have put out some rocks to walk on. this is not a good trail for dogs, although they're allowed, there is quite a bit of rock climbing that you'll want free hands for. also not good for small children, 1 slip and you're seriously injured. I've seen little kids on the trail, and most turn back and head back to the car, going up is much easier than going down. there is no warm up from the beginning of the trail it's a pretty steep hike up the mountain, with amazing views. if you decide to go to the park across the highway, that section of the trail is very confusing, it's fairly well marked, but the maps contradict themselves, and its very easy to get lost. I'm an experienced hiker and I got turned around a few times..you're much better off doing the trail I outlined, if you want to hike longer, stay on the Appalachian trail to outlook, and turn around and come back. the route in described is a loop right around 4 miles, it took us 4 hours to do with kids. there's a lot of loose rock, make sure no one is directly above you kicking rocks loose. this is one of the most advanced sections of the Appalachian trail in the area, arguably in Pennsylvania

Really fun hike! As others said, the initial mile is a lot of incline, but once you get to the Scenic Route split (highly recommend the Scenic Route) it flattens out. The South Trail near the end of this route is where all the boulders are - it’s a challenging mile but well worth it for the views. I didn’t see anyone else on the Scenic or South trail but there’s a good number of people on the main Appalachian Trail.

Great workout! However I would not bring a dog up the first mile on the white trail. There were a few spots where I had to pick him up and place him up higher. ( Australian Shepard) The very last leg he couldn’t manage and I couldn’t lift him up so we had to turn back and go up the blue trail.

Good trail. We did not home the full length but felt we had had a good workout with good views. Very steep climb at the start. Not much of what I would truly define as a rock scramble but that may have been fatter down the trails. The views we did have were beautiful and wide open.

This was indeed a difficult day hike, with tons of rocks - a real ankle-buster. It had a steep incline for the first mile or so. It was very rewarding, we ran into very few people, and you have the option to continue in the AT where in the next mile you’ll find a rock scramble. Take the North (blue blazed) side trail for amazing views.

Great trail. In good condition, although hard-packed snow and icy in spots around the summit elevation.

It was actually a pretty good hike, Did it for the first time with two of my buddies definitely recommended! A little disappointed that I didn’t finish the whole trail but did about 90% of it.

Lovely trail, medium difficulty. Most of the trail goes through the woods, so it was okay to do on a hot June day. Met several thru-hikers on this segment.

Nice trail, clearly marked and easy to follow. you'll have to cross the chain bridge and make a right into a small parking lot with a marker for the Appalachian trail. walk back across the bridge and cross the street at the end, this is the trail head. lots of gas stations on the way on close by. As said in other comments the first mile or so its a steep rocky climb and will definitely be a good work out so come prepared to start strong. At the top of this section there is a spring and a little structure with a visitors log and a fire pit. continue on to see a sign that indicates the north trail heading to the right. this route is easy to walk and has beautiful views and plant life. This trail Continues past some radio towers and over the lehigh tunnel then loops back around to meet the white trail again. You can follow this back to the start and get some nice downhill sections you can run if your into that, although I don't recommend doing so unless you are experienced as it is dangerous and easy to hit a rock and fall while running. There were also a bunch of woodpeckers around this section. For a more challenging route take the white trail first to hit those inclines instead. I would defintely have a good sturdy pair of boots, this trail is very rocky in parts with a fair amount of loose rocks.

Really pretty fall hike. Also relatively uncrowded even though it was a beautiful Sunday. I did the north trail, followed the AT a little ways further, and then went back to the parking lot via the south trail. I definitely wouldn't rate this as a hard hike, but the initial part was a nice little climb.

Overall, a great hike with lots of views. Made a loop of this going up the AT and returning down via North Trail > Charcoal > Prairie Grass > L&NE Trails. There aren't really any views initially at the top unless you continue over the Lehigh Tunnel to the South Trail or loop back on the North Trail. The South Trail has several spots of wide views among piles of large rocks. The North Trail also provides a nice consistent view on the other side almost along the entire stretch until it declines down to the Charcoal trail (mostly exposed meadow trail which was nice change from initial ascent in shaded forest).

First mile is strenuous uphill, but after that, take north loop which is scenic and relaxing. Great views of the valley. The AT is relatively flat, gently rolling. Great hike overall, don’t let the first mile discourage you. Pace yourself up the climb, you will be rewarded!

Good hike experience with the nature and adventure. Although it’s flat after the first 2 miles. It’s challenging with rocks all over. Great feel after doing 12 miler

Really fun hike along the AT. Take the North Trail where it splits off from the AT for the best views on a clear day. And the South Trail is a lot of fun - if you enjoy a good rock scramble!!

Initial incline is a real leg burner, but the views are worth all the work. This was a fun hike, different terrains, areas that become slightly challenging, but it was a never ending cycle of scenery and ridge views. Def recommend

Tough ascend from the start for circa 45 minutes. Interrupted the ascend with talks to the 5 or 6 AT hikers we encountered, especially near the well where they collected/treated the water that came out of a little pipe (identified by a white sign on the tree above it). Hiked on the AT until the 2nd entrance to the North Trail (near the 476 Tunnel). Then took the North Trail East, then the charcoal trail, then the Prairie Grass Trail, then the D&L Trail along the river back to the car. All was relative well marked. I think we hiked for circa 6 miles and it took us a bit more than 4hrs. Views on the North Trail were fantastic but the noise from the cars below did not make it very peaceful (that is why I rated this hike 4 stars). Came across lots of different types of vegetation and trails. Came across and ate wild blue berries and black raspberries. The descent down the Charcoal trail was the hardest due to all the stones and boulders on this trail. Was a pleasure to walk down the Prairie Grass Trail towards the river.

Very steep heading up but once you get to the North Trail it levels out just in time for the views. Well worth it. Woodpecker Trail to North Trail then Appalachian Trail back to Woodpecker put us somewhere just over 5 miles.

Took the woodpecker trail to the AT then took the north trail on the way back. A stunning variation of plants and wildlife there. This trail is fairly easy and very fun.
