First, Some Quick History
Mount Katahdin was originally named by the indigenous people of the Penobscot Nation. The word Katahdin translates to “The Greatest Mountain,” and was said to be home to the thunder god, Pamola. Legend has it, Pamola guarded the mountain and forbade anyone from climbing to the summit. Mount Katahdin is Maine’s highest peak, and its unmistakable silhouette can be seen from miles away.

Mount Katahdin Knife Edge Trailhead: Getting Started
Right next to the Roaring Brook Campground lies the Chimney Pond trailhead, where you’ll begin your ascent to Mount Katahdin and the Knife Edge Trail. Like my most hikes, it’s always a good idea to get an early start and beat the crowds, especially if you’re hiking during peak season.

You’ll begin the trail hiking alongside Roaring Brook with little to no elevation gain. A few miles in, you’ll reach Basin Pond and cross paths with the North Basin trail. From here, you’ll have about approximately one more mile until you reach the Chimney Pond campground.
Once you’ve reached Chimney Pond you’ll be staring up at Mount Katahdin and the Knife Edge trail. As you continue up the trail you’ll see three distinguished rock formations known as the “cathedrals” on the right ridge. This is the most common and shortest route to the summit.

Cathedral Trail to Mount Katahdin
The Cathedral trail begins by the ranger cabin just before the pond, can’t miss it. This is where the hike starts to get interesting. The next mile of the hike is a steep rock scramble as you climb above the tree line. During this short but strenuous stretch, you’ll climb over 2,000 feet of elevation.
Once you’ve reached the top of the third and final cathedral, you’ll continue to the junction with the Saddle trail. Once you reach the junction, the Katahdin summit is a short hike away. You’ll approach a large rock cairn and the iconic Katahdin sign. Once here, you’ve officially reached the northern terminus of the Appalachian Trail. Be sure to take a moment to savor the view, take a picture with the Katahdin sign, and prepare for the Knife Edge trail.

The Knife Edge Ridge
The Mount Katahdin Knife Edge trail begins right near the summit cairn. On both sides of the Knife Edge trail lies treacherous slopes of rocky debris. The first quarter-mile of the Knife Edge trail leads to Mount Katahdin’s south peak. From here, the trail slowly descends as the ridge bends around the basin.
But you’re not done yet. The second half of the Mount Katahdin Knife Edge trail gets even more demanding. As you continue through the ridge, you’ll reach several vertical ascents and sharp descents as you climb Chimney Peak and to the top of Pamola Peak.

The end is near as you begin to descend the Helon Taylor trail towards the tree line. You’ll continue steadily downhill for a few miles where the trail will eventually level out once you reach the forest. After hours of vigorous hiking, the Mount Katahdin Knife Edge trail will conclude at Chimney Pond and lead you back to the Roaring Brook campground and parking area.
Final Thoughts
Completing this hike will take determination and resolve. You should not attempt the Mount Katahdin Knife Edge hike unless you’re confident in your ability as a hiker. But, if you’re up for the challenge, I promise it will be a hike you’ll never forget.
