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.

The north and south scenic trails made it worthwhile. The views are great on the north side. The south trail is basically a mile of boulder hopping. A great adventure if you have the right shoes! The AT sections were fairly meh. I thought all of it was marked pretty well.

One of the more strenuous trails I've hiked, with the gain being somewhere around 900 feet / mile. The trails coming off the AT - particularly the North Trail - are not the best marked, but when you find them you will be blown away by the views!

Took North and South scenic trails, which are more difficult and have a lot of sun exposure. The AT sections were easier and had coverage. Great loop. Wear sunscreen and a hat!

It was tough to do and an awesome challenge. But take the “scenic route” that is an off shoot of it. It adds a little bit of distance but walks along the open side of the mountain.

Views in the winter are much better, especially with snow providing a contrasting backdrop.

We did the Appalachian trail and Blue trail loop. Great day hike with views on blue trail

Great hike, though I'd call it an intermediate following the regular trail— only if one takes the south trail loop (as shown in map) does it become a difficult trail, with lots of seriously fun but occasionally treacherous rock scrambling. Great views at certain spots, there's a spring about one mile from the trailhead. Overall, a pretty decent day hike, even in late November.

Solid hike with my dog. Beautiful weather and some nice views. Just a few other hikers on the trail. Peaceful.

First 1/2 mile is steady uphill but well worth it! Lots of snakes today (6 that we laid eyes on) but the views were spectacular! Trails are exceptionally well maintained and marked. Huge thank you to those who recently weed whacked the trails!

A tough uphill for the first mile or so but the North Trail views were spectacular and so worth the climb. Definitely going back in a few weeks.

Good hike...We turned this trail into a loop trail by starting with Woodpecker trail at the Nature Center, AT, then second entrance to the North Trail, came down to Charcoal trail and then Prairie Grass trail around back to Nature Center. Approx. 7 miles.

Good hike. Used five of the trails to make a 7 mile loop. Warning that the Charcoal trail is NOT well maintained. Had a great hike and the scenery was spot on. Great day!

Love this trail although be careful as the connecting winter trail shows up incorrectly on the app. We go totally lost for hours in the heat with no food or water left. It was a bad situation but than goodness we found our way back to the trail and met up with some awesome hikers that gave us water! Never leave the trails my friends!!!!

Nice trail with a fairly significant steady incline for the first 2 miles. Nice shade with rest area and flowing water too. Enjoy!

It was a great hike! Although it wasn't as difficult as the description said it'd be.

I didn't go as far back as this trail says, but I did the loop. It is a fun, beautiful trail. You do need to be okay hiking uphill for a while, but I like that it's rocky and not completely smooth...which can be difficult for some people. the view isn't the best though, in spring trees block your way to seeing the other side of the gap
