Knife’s Edge. The name itself a sense of awe, wonder, and well-deserved trepidation. Since the park started keeping track in 1933, over sixty people have died on Katahdin, many of them on this wildly exposed mile-long ridge. Only three-feet wide in places with 1500 ft drops on either side, this trail requires steady nerves and careful foot placement. But if you’re prepared and you hit it on a good weather day, it is truly one of the most incredible hikes in the Northeast.

Before hiking Knife’s Edge, I’d summited Katahdin via the Hunt and Abol trails, which both approach from the southwest. Both are hard—all the trails up Katahdin are—and involve climbing over rocks the size of small cars. From Chimney Pond on the east side of Katahdin, hikers have the option to ascend via Dudley, Saddle, or Cathedral trails, but only Dudley takes you to east end of Knife’s Edge (Helon Taylor from Roaring Brook Campground also brings you there). It is generally considered *slightly less terrifying* to hike Knife’s Edge from east to west because you are climbing versus descending.

The Chimney Pond Trail from Roaring Brook parking is 3.3 miles and gains a moderate 1,425 feet of elevation. It follows an old logging tote road, traveling along Roaring Brook and passing the Basin Ponds, sites of a long-gone logging camp. The trail ascends into the Great Basin, a horseshoe-shaped glacial cirque that encloses Chimney Pond on three sides with its 2000 foot granite walls. Standing on the shore of the pond and staring up at the imposing wall of the basin in a truly humbling experience. The world is big and beautiful and magical and we are so, so tiny.

Situated on the edge of the pond, Chimney Pond Campground has lean-tos and a bunkhouse (no tent sites) and definitely necessitates reservations well in advance, especially for summer weekends. This is one of the most popular places in the park. You may be able to find an open spot on a random weekday, like I did, but flexibility is required if you’re planning less than a four months out. Like the rest of Baxter State Park, the water at Chimney Pond requires filtering and you are strongly encouraged to use the bear bag hoist system. There are also no campfires permitted at this campground, so bring a stove.

For this trip, I hiked in from Roaring Brook trailhead to Chimney Pond Campground, dropped my overnight gear at the lean-to, and got started up Dudley around noon. Dudley was closed from 2016 until 2021 due to unstable conditions caused by a rock slide (this section has been rerouted), and my hiking partner was excited to see the newly opened trail. The first mile travels through a boulder field at the base of Dudley Ridge. A half-mile up the wooded, eastern flank the tree growth ends and the trail becomes extremely steep and fully exposed. I was hiking this in late September, in full sun, and it was hot. I would imagine a similar day in July or August could be sweltering. At any time of year, especially on a sunny day, I would bring at least 3 liters of water, a lot of snacks, and salt tabs for dehydration cramps.

Crossing Knife’s Edge

Dudley Trail ends at the 4,900 foot Paloma Peak. From there, Knife’s Edge descends STEEPLY into the col between Paloma and Chimney Peak. Three hundred feet down in .1 mile, and then right back up, requiring full contact (hands and feet) with the rocks at all times. This is the most technically challenging part of the hike. I climb rocks for fun, and I found this chimney pretty darn terrifying. This is an absolute no-go in bad weather. Actually, all of Knife’s Edge is a no-go in high-winds, lightning, or heavy rain. The rangers will, at times, close the summit to keep hikers safe. Disobeying their directive is not only disrespectful, it’s foolishly arrogant and downright dangerous. You could get hurt (or die), and if you do get hurt, others will have to put themselves at risk to help you. You’ll feel like an ass and will most likely be handed a hefty fine. So, don’t do it.

The official guidebook for Katahdin, complied and edited by Baxter State Park, gives the following warning:

“[Knife’s Edge] should not be attempted in poor or marginal conditions. Do not attempt to leave the ridge once you have started. Several ravines have the dangerously misleading appearance of an easy short-cut descent off the ridge toward Chimney Pond. These lead to almost vertical drops which are impossible to negotiate without technical equipment and experience.”

But, let’s assume it’s a gorgeous day in September and you’ve carefully made your way down and back up the chimney! Now you have a mile of jagged, narrow arete stretching out in front of you. And one of the most breathtaking sights you’ve ever seen. The path across the ridge is only three feet wide in places, with 2,000 foot drops on either side. There are sections that are wider, but the whole thing is rocky and uneven and requires thoughtful foot placement and balance.

The trip across Knife’s Edge took about an hour. It could take a lot longer, depending on your comfort level with heights and precarious footing. It’s also a steady uphill from Chimney Peak to Baxter Peak, not a flat ridge, so be prepared to climb almost 400 feet. At Baxter Peak, you’ll get to touch the famous Katahdin sign, experience the northern terminus of the Appalachian Trail, and look back at the insane glacial feature you just crossed.

After taking lots of pictures, I headed down the Saddle Trail, which begins its descent gradually over the Tableland, a sloping alpine plateau made of pinkish rocks and scrubby grasses. At one mile, Saddle Trail turns right and drops over the rim of the Tableland, into the Saddle Slide. Of all the steep and rocky trails leading back to Chimney Pond, this is the least steep… which isn’t much of an endorsement for ease, but the worst of it only lasts about a quarter-mile. The footing here is loose and gravelly, and care must be taken not to dislodge rocks that could injure hikers below. After crossing a small brook at .4 miles from the drop, the trail becomes more gradual and reaches Chimney Pond at 2.2 miles total from Baxter Peak.

This whole loop took about 5.5 hours, and that included a long break at the summit and a stop to address heat cramping in my hiking partner’s legs. That said, I was really glad to be camping at Chimney Pond instead of pushing through another (albeit easier) 2.3 miles to reach Roaring Brook, which so many hikers we chatted with were doing. It’s absolutely doable as a day hike (plan on 10-12 hours), but if you can stay at Chimney Pond either before or after summiting, do it!

Total elevation: 5268 ftElevation gain: 2454 ft

View payoff: the bestDogs: No!

Recap: Knife’s Edge is arguably the most stunning and most storied feature of Katahdin. It is a truly breathtaking geological phenomenon and a bucket list item for any experienced hiker. However, this mile of narrow, jagged trail edged by nearly 2000 foot drops on either side is not a good choice for those with significant fear of heights, rock climbing, or falling. It is also something only to be attempted in good weather (not in heavy rain, wind, or lightning). Staying at Chimney Pond breaks up this very strenuous hike. Dudley Trail is a hard, fun climb over big boulders, and Saddle Trail is the easiest of all the not-easy-at-all options down. Use caution on the loose, gravelly terrain when descending.
