Great views, challenging ascent, sometimes a little crowded at the summit. This trail is a great warmup before larger trips to New England or out west. A short yet somewhat challenging hike. The red trail has the challenge of steep uphill portions with the reward of a beautiful outlook at the peak. The way down the blue trail is very pleasant as you see new scenery which includes a winding path through the trees and running water. There is even a small pond that you can cliff-jump into.

It’s my favorite hike the area. It’s short, great view at the top, and waterfalls on the Dunnfield creek at the bottom. But y’all. Stop leaving trash. Orange peels, apple cores and banana peels are all still trash. Would those items be there if we weren’t? Anything you bring into the woods should come back out.

Challenging but overall a short hike. I combined this with the Sunfish Pond loop and it made for an 11 mile (+/-) hike. I chose to follow the Dunnfield Creek path on the way to Sunfish. Didn’t see a single person. This trail was definitely more adventurous with numerous stream crossings, some washed-out sections of trail, and large spots of ice. After Sunfish Pond I stayed on the AT and passed dozens of people gojng the other direction. The AT was a far easier walk back to the car. Looking forward to doing this again in he spring.

First thing I’ll say is red dot to blue dot blazes is the way to make this hike. Experienced hikers with proper footwear could go up red dot and back down red dot, but much more rewarding to take blue down. Easier on the knees and a different style hike. I made the hike in icy and snowy conditions so would recommend the trail any time of year. A little less than 2 hours if you’re moving, but take your time as you will have multiple views of the gap along your way. Red dot trail is to your right as soon as you enter the parking area. If you find yourself crossing a bridge and seeing white blazes immediately, you are heading toward the blue dot trail (this is the way you will exit the woods back to the parking lot).

A short yet somewhat difficult hike. This hike has the challenge of steep uphill portions with the reward of a beautiful outlook at the peak. The way down is very pleasant as you see new scenery which includes a winding path through the trees and running water. There is even a small pond that you can cliff-jump in to. The first time I hiked this trail I even saw a young bear! (Check it out in the gallery). This hike was a great experience all around. Those planning to come here should allow themselves ample time to take breaks and appreciate their surroundings.

Great cardio hike with varied terrain. 35-45 min up red to the top and 40-45 min down blue.

Lots of rocks and very steep on the way up. We went during hunting season so dressed our teenage girls in orange (which they “loved”) They complained some because-teenage girls, but they raved about it and loved their instagrammable pictures afterwards. Loved getting these screenagers somewhat off the grid. Mostly rocks even on the back side (blue dot). Finally got to some smooth trails near dunnfield creek which felt like butter on the feet after all the rocks. Go early though as the lot fills up fast. We got a spot no problem but on the way out the ranger had the lot coned off.

It's a light to moderate hike. Views (about a quarter way up which take about half an hour) are wonderful and relatively accessible to the average fit person. The entire hike to the top took about 2 hours.

Great but challenging trail. We ascended on the red and descended on the blue. The red is difficult, in my opinion, for those non-experienced hikers like my group. The view from on top is incredible. I would recommend good hiking boots as it's a rocky terrain. The blue dot is challenging but not as bad and leads to a lovely waterfall.

Beautiful, and totally worth it. It was slow going & hard on the knees with the very steep, rough terrain.

Stellar views of the Water Gap make this well worth the hike!

Incredible trail but hardly moderate. Starting at Red Dot is over 1,000 ft climb in under a mile, a bunch of which is rocky. The descent along the blue dot is incredibly rocky and a strain on quads and knees. I would categorize the hike as moderate for the athletic/in-shape and strenuous for those who don’t hike often. However, this that persevere are treated with incredible views and a crystal clear waterfall.

Great trail. The view at the top is definitely worth the effort. We ascended via Red and descended via Blue. 99% of the Trail in both directions is rocks so make sure you have good shoes. If you ascend on Red, I would rate it harder than moderate.

Awesome views of Pennsylvania from the NJ side of the water gap. Bring your bathing suit for a jump in a swimming hole on the way out. Check out my full write up which includes directions and things to look out for.
