Great views, challenging ascent, sometimes a little crowded at the summit. This hike is a great warmup hike before larger trips to New England or out west. We always do our training here because it never gets old and the ascent is a good measurement of your physical preparedness. Good trip for dogs.

It's best to have a good pair of hiking boots during the winter months for this rocky terrain with some steep inclines. This is especially true when the snow falls as it so happened on our hike. A slippery challenge at times.

Started out early on Veteran's Day. Only 3 other cars in the lot when I headed out. I've hiked this loop several times over the years: nice mix of inclines, declines and flats. Of course the view up top is great, but being a holiday, lots of people up there. When I finished up a few hours later, lot was overfilled.

This is great trail with awesome inclines which gives it a little challenge. The colder months are quiet and peaceful as it's less populated, and the view is still just as gorgeous.

This is the second time I've done this hike. It's beautiful, and fun, but I hate how busy it always is and being right next to the highway sucks. The only reason I did it again is because days are so short right now and I live in south jersey. This will be the last time I do this one, next time I'm going to do Mt.Minsi.

Went at 9 am on the Wednesday before Thanksgiving. Park wasn't packed, saw maybe a dozen or so hikers on my 3 hour trek. I didn't see any snakes, but was careful where I stepped. The trail was rugged, steep and challenging. I would recommend trekking poles, even one would have helped. I went up the red dot trail and came back down the same way. I'd recommend having a backpack with water, tissues and a first aid kit. A few times I lost my footing, especially coming back down the rocky steep trails, and a fall would have been disastrous. I highly recommend this hike and would do it again.

Very busy trail and the erosion shows heavily in some spots. Three hour round trip with young kids (5 & 7). Amazing views. Nice swimming holes.

Very nice trail, but very strenuous all of which pays off in the end with the overlook of the Delaware River.

Took red trail up and blue trail back. Red trail was definitely plenty challenging, lots of elevation gain, and very rocky terrain - nice cardio. Poles wouldn't be a bad idea, as falling is a possibility with all the rocks. Though I saw people without them, I'd say hiking boots are a must, otherwise pack an extra pair of ankles. ;)

View up top was worth the climb for sure.

Blue trail down was easier, and a nice view of the creek at the end. Took just under 2.5 hrs with plenty of photo stops. All in all a great hike - trails were well marked plus it was very crowded, so almost no chance of getting lost no matter how you do your loop.

Start from the Red marked trail. I followed the instructions from njhiking.com So check it out if you have time.

The hike was moderate. Almost like Stairway to Heaven (if you've been there before). It's very tiring and very challenging but it's all worth it to the top, trust me. On the way to the top, there are some spots that have scenic views. But nothing beats the top view haha.
