Extremely challenging trail along steep, loose rock pile atop 2000 ft cliffs; fantastic views. The Knife edge is very rugged in places - the Chimney is almost a technical climb. The Baxter Peak side of the Knife Edge is a boulder scramble. The gap between Pamola and Chimney peaks can be very challenging because it is very steep and many of the rocks you have to climb up lean in towards the gap. These can be very dangerous in wet weather. Proper equipment and experience are a requirement. This hike should not be taken lightly and you should listen to the rangers prior to making the climb. There is not much help around if you run into trouble. This route is completely exposed and several people have died or have been seriously injured while attempting a traverse in inclement weather and/or high winds. Do not attempt to leave the ridge once you have started. Hiking Knife Edge across and back is not recommended due to its difficulty and the amount of time it adds to the hike it takes approximately 1 to 2 hrs. one way. Access to Knife Edge is from the Roaring Brook Campground. Hiking it from the Hunt or Abol Trails means ending at Roaring Brook Campground, an hour by road from your vehicle on the other side of the mountain. Shuttle service is not provided. Rangers will allow you to pick up if after about 3PM. There is no water on this trail. Trailhead Parking Lots: Roaring Brook Campground, Abol Campground, or Katahdin Stream Campground Note rangers require you to carry a flashlight.

Hands down my favorite hike. Challenging with scrambling, some climbing (the Chimney), epic views for the entire trip. One thing we found out the hard way- you have to make reservations to hike this mountain!

We did an absolutely awesome up and over starting from Katahdin Stream up the Hunt Trail to Baxter Peak, across the Knife Edge (top to bottom), and down the Helon-Taylor trail, about 10 miles and 12 hours (we took lots of pictures and videos). The Knife Edge is really a technical non-technical trail due mostly to the part between Chimney and Pamola Peaks, where the trail goes vertical. Being tall gives you an advantage to reach the handholds and foot placements. Be sure to stay focused during the whole trek, as one mistake can cost an ankle, a knee, or your life. I would not recommend doing this hike in wet or very windy conditions. We had a beautiful day, with clouds in and out. The views are amazing. If you don't get vertigo, can handle lots of rock scrambling and free-climbing, and really enjoy a challenging hike, this one is for you. I highly recommend it...

Wow. Just wow! We were there during high winds and got hit by hail several times. Took forever to get across but the view is unbelievable and the pictures last forever.

Look, I have a fear of heights. I was pretty sketched out a couple of times on this hike. So glad I did it. Amazing.

Amazing hike, incredible views and very thrilling! Not for people with fear of heights though... All the descriptions of straight drop offs are pretty accurate.
