Mount Katahdin is the tallest peak in Maine and the dramatic northern end of the Appalachian Trail. But the real showstopper is the Knife Edge, a narrow exposed ridgeline with steep drop offs that feels like you’re walking on the spine of a dinosaur!

This hike quickly became one of our favorite New England hikes ever… it’s the perfect blend of challenge, adrenaline, and epic views.
If you’re planning a trip to Baxter State Park and are ready to tackle Maine’s tallest peak, here’s everything you need to know before your hike.
Overview: Mount Katahdin via Cathedral Trail & Knife Edge
Hiking Katahdin is a bit of a “choose your own adventure”. Baxter Peak (the highest peak/summit of Katahdin) can be reached (and descended) by several trails, each with its own vibe.
The most intense sections are arguably Cathedral Trail and Knife Edge, which is what we’ll be sharing about today.
Trail route:
Chimney Pond → Cathedral Trail → Baxter Peak → Knife Edge → Helon Taylor Trail (outlined on map below)
Location: Baxter State Park, Maine
Parking: Roaring Brook
Distance: ~9.5-mile loop
Elevation gain: ~4,000 ft
Difficulty: Strenuous + highly technical
Highlights: Iconic Knife Edge ridge, panoramic alpine views, summit of Maine’s highest peak
What to Expect on Each Section
Roaring Brook
Hopefully, you got your trailhead/parking pass for Roaring Brook (more on that below). Here you’ll find toilets, a ranger station, and camp store. It is important to note that there is no running water here. Gather your belongings and head to the Chimney Pond trailhead. Make sure to bring a pen to sign the trail register (why are there never any pens?)
Chimney Pond Trail
Chimney Pond Trail is a perfect way to start the day. This 3.3mi rocky trail starts gradual and becomes moderate with 1,425 ft elevation gain, allowing for a good warm up.
This trail ends at Chimney Pond Campground where there is also a ranger station and the most beautifully clean vault toilet we’ve ever had the pleasure of using.
Cathedral Trail (Ascent)
This 1.5mi Cathedral Trail section is the steepest, most technical part of the day. If you’re not into scrambling or heights, Cathedral Trail is not for you.
Expect to be doing some legit rock climbing moves with 2,353ft of elevation gain. You’ll be impressed by massive boulder sections.
Be sure to turn around to take in the views — the majority of this section is above the treeline and the views are epic!
At the end of Cathedral, you’ll turn left onto the Saddle Trail and follow this briefly (0.2mi) on the final ascent to Baxter Peak.
Baxter Peak
At the summit, you’ll get 360° views of Baxter State Park’s rugged wilderness (assuming that it’s not all fog like we experienced). Be sure to take a picture by the famous sign.
Find the survey marker. You’re standing on the highest point in Maine! Hopefully you packed a picnic to enjoy at the top (we brought delicious leftover pizza from dinner at Knife Edge Brewing the night before). Catch your breath and prepare yourself for tackling the legendary Knife Edge.
Knife Edge Ridge
Narrow. Exposed. Windy. Dramatic. Stunning. Slightly terrifying.
The Knife Edge is all of these things at once, and that’s why it’s one of the most iconic sections of any hike in the Northeast. Some parts of this 1.1 mile trail are only a few feet wide with steep drop-offs on both sides. This is a fully exposed ridge with no protection from the weather. High winds and bad weather have led to fatal and serious accidents here, so do not attempt if this is the case. Take it slow, and stay focused!
Don’t be afraid to get low– I was definitely on all fours traversing some of these sections!
It is important to note that we are experienced hikers and also have top-rope rock climbing experience, and the last connection from the Knife Edge to Helon Taylor even made us a little uncomfortable (especially since we didn’t have health insurance at the time!) You’re pretty much scaling down a 4 story building, then climbing back up the same thing on the other side. This is not a trail to be taken lightly. There are less technical descents if you have any doubts!
Helon Taylor Trail (Descent)
Compared to the rest of the loop, Helon Taylor feels like a victory lap. It’s still steep, but much less scrambly and offers sweeping views of Pamola Peak. The first portion is very exposed with great views.
See if you can scout some wild Maine blueberries!
Important Notes
1. Parking reservations are required
Katahdin trailhead reservations open April 1 at 6am EST for the summer season, and they sell out FAST. We recommend getting familiar with the Baxter State Park reservation site ahead of time. Read through all the trail descriptions, plan your route, and figure out where you’ll need to park (Katahdin Stream, Abol, or *Roaring Brook). Create an account, and add your vehicle information (your parking reservation is linked to this, and you can’t make a reservation without it). On the day of, set an alarm and log on 5 minutes before. Have the World Clock open on another screen or device, and refresh madly at 5:59:59 am to ensure you get your top pick. We missed out two years in a row and finally grabbed a random Wednesday slot in August.
2. You MUST arrive by 7 AM
Congratulations! You’ve snagged a trailhead/parking pass to hike Katahdin! Take a screenshot and/or print your parking reservation and trailhead passes to present upon your arrival. You will very likely not have any cell service to be able to pull this up online.
Now don’t forfeit your opportunity to hike! If you’re not in line at the Togue Pond Gate by 7am, your reservation is released to standby hikers. On the other hand, if you didn’t snag a spot, this is your opportunity! Hopefuls without trailhead/parking passes sometimes line up an hour or two before 7am so they can snag the first released reservation, so get there extra early if you want a shot!
3. Costs
- $10 per car for a day-use parking pass
- $20 per non-Maine-resident per hiker
- Maine residents hike free
4. Be Prepared
- Hiking Katahdin is no joke, and you need to be prepared for anything. At a minimum, you should carry the 10 essential items: map (see below), compass (make sure you know how to use this!), warm clothing, rain/wind gear, whistle (check to see if your hiking backpack has one built-in!), flashlight/headlamp, extra food and water, first aid kit, matches/fire starters, and a pocket knife.
- Cell service is virtually nonexistent in this part of Maine (though we managed to make an important call from the summit… more on that another day).
- Print a paper map ahead of time or purchase one for a small fee at the ranger station. A screenshot of your route saved to your phone is a smart backup too. If you’re using offline navigation (we love AllTrails for this) download your maps before you leave and pack a portable charger.
4. No Dogs Allowed
- Baxter State Park has a strict No Dogs policy : (
4. Where to stay
Baxter State Park has multiple campgrounds and lean-tos near Katahdin, but they also require an advanced reservation, and fill quickly! Parking permits are not required for Campers hiking Katahdin the day after check-in. If you don’t feel like camping, the nearest town with accommodation options is Millinocket ~45minutes away.
Is the Knife Edge Right for You?
Katahdin is a tough hike no matter which trail you take.
The Chimney Pond → Cathedral Trail → Baxter Peak → Knife Edge → Helon Taylor Trail loop is perfect for experienced hikers who love technical scrambles and ridgelines that make your palms sweat.
If you’re newer to hiking, nervous about heights, unsure of your footing, or don’t have health insurance, we’d recommend taking the Saddle Trail. It’s less technical, but still a challenging full-day hike. (Chimney Pond → Saddle Trail → Baxter Peak and back down the same way.)
Leave No Trace
Baxter State Park is one of the most pristine wilderness areas in New England. Please stay on trail, pack out everything, and follow Leave No Trace principles to help keep it wild!
Final Thoughts
Mount Katahdin lived up to the hype and then some. The combination of Cathedral’s hands-on climbing and the Knife Edge’s adrenaline-pumping exposure makes this one of the most incredible hikes in the region. We’d say Maine’s highest peak is an absolute must-do for any New England adventurer.
