I stood at the edge of the Lairig Ghru, staring at the wall of rock I had to climb. The map said it was a path. The map was lying. My legs were already cooked from the slog up Braeriach, and I hadn’t even touched the ridge yet. That was my first mistake — underestimating the distance between these four Munros.
Braeriach, Angel’s Peak, Cairn Toul, and The Devil’s Point. Four mountains. One continuous ridge. Twelve miles of exposed walking above 3,000 feet with no escape route. If you’re reading this, you’re probably planning the same loop and wondering if it’s doable in a day, what gear you actually need, and which section will break you.
I’ve done this route three times now. Twice in good weather, once in a whiteout that taught me exactly what my gear could and couldn’t handle. Here’s what I learned.
Why This Ridge Walk Is Different From Every Other Munro Circuit
Most Munro bagging involves hiking up one mountain, going down, then driving to the next car park. This route is the opposite. You park once, walk for 10-12 hours, and cover four of the highest peaks in the UK without dropping below 3,000 feet for miles. The continuous exposure changes everything.
The Lairig Ghru approach alone filters out half the people who attempt this walk. It’s a 5-mile approach from the car park at the Ski Centre to the base of Braeriach, all on loose boulders and eroded path. You gain 1,500 feet before you even start climbing the mountain. Most people burn their legs here and suffer for the rest of the day.
What makes this ridge genuinely special is the geology. The granite here is ancient — 400 million years old, weathered into these sharp, angular forms that look more like the Alps than Scotland. The corries drop away 2,000 feet vertically on either side. One wrong step on the section between Braeriach and Angel’s Peak and you’re sliding into the Garbh Coire Mor. That’s not hyperbole. That’s the reality of walking on wet granite slabs at 4,000 feet.
The weather window is brutally narrow. The Cairngorms have their own climate system. I’ve been on the summit of Cairn Toul in July with snow at my feet and a hailstorm coming from a blue sky. The Met Office mountain forecast is your lifeline here, not the general forecast for Aviemore. If the wind is forecast above 40mph, don’t go. The ridge becomes genuinely dangerous.
The Route: Breaking Down Each Section With Real Timings
I’m going to give you the timings that work, not the ones the guidebooks claim. Guidebooks say 8-10 hours. I’ve done it in 9 hours on a perfect day and 12 hours in mixed conditions. Plan for 11 hours and be happy if you finish earlier.
| Section | Distance | Ascent | My Time | Difficulty |
|---|---|---|---|---|
| Ski Centre car park to Lairig Ghru floor | 5 miles | 1,500 ft | 2 hours | Moderate — loose boulders |
| Lairig Ghru to Braeriach summit | 2 miles | 2,200 ft | 1.5 hours | Hard — steep, no path in places |
| Braeriach to Angel’s Peak | 1.5 miles | 200 ft (undulating) | 45 minutes | Moderate — exposed ridge |
| Angel’s Peak to Cairn Toul | 2 miles | 600 ft | 1 hour | Hard — scrambling sections |
| Cairn Toul to The Devil’s Point | 2 miles | 300 ft (descent then climb) | 1 hour | Moderate — steep descent |
| The Devil’s Point back to car park | 6 miles | 500 ft (mostly descent) | 2.5 hours | Long — knee-crushing descent |
The section that catches people out is the descent from The Devil’s Point. It looks straightforward on the map — follow the Allt a’ Garbh-choire stream back to the Lairig Ghru path. In reality, it’s 6 miles of steep, wet grass and heather with no proper path for the first 2 miles. Your knees will hate you. I use trekking poles specifically for this section. Without them, I’d have fallen at least three times on wet rock.
Braeriach to Angel’s Peak: The Ridge Walk That Actually Matters
This is the section that separates this route from every other Munro walk. The ridge between Braeriach and Angel’s Peak is narrow enough that you can see both corries dropping away at the same time. On a clear day, you can see Ben Nevis 60 miles to the west. On a bad day, you can’t see your own feet.
The path is obvious in good visibility — it follows the crest of the ridge. In mist, you need to navigate by bearing. I’ve watched people wander off towards the Garbh Coire Mor because they followed the slope instead of the compass. The bearing from Braeriach to Angel’s Peak is 145 degrees magnetic. Lock that in before you leave the summit.
Cairn Toul to The Devil’s Point: The False Summit Trap
From Cairn Toul, The Devil’s Point looks close. It’s not. The drop between them is 300 feet down steep scree, then a climb back up. The scree is loose — the kind where every step slides back half a foot. I’ve seen people turn around here because they didn’t have the energy for the climb back out.
The Devil’s Point itself is a sharp pyramid of granite. The summit is small — maybe 10 feet across — with a 1,500-foot drop on three sides. This is not a summit for people who don’t like heights. The exposure is real. I sat down to eat my lunch here and didn’t stand up until I was ready to leave.
Gear That Actually Matters for This Route (And What You Can Leave Behind)
I’ve done this walk with a 35-liter pack and with a 20-liter pack. The 20-liter pack was better. Here’s exactly what I carried and why.
The Shell Jacket Decision
This is not a walk where a cheap waterproof works. The wind at 4,000 feet in the Cairngorms will find every gap in your jacket. I use the Montane Minimus 777 (£180) — 120 grams, fully taped seams, and a hood that actually stays on in wind. The alternative is the Rab Phantom (£160) which is lighter but less durable. For this route, durability wins because you’ll be scraping against granite on the scrambling sections.
What I don’t use: insulated jackets. You generate enough heat on the climbs. I carry a Patagonia R1 fleece (£130) as my mid-layer and only put it on during breaks or on the ridge if the wind picks up. The R1 breathes well enough that I don’t soak it with sweat, and it dries in 20 minutes if I do.
Footwear: The Difference Between Enjoyment and Suffering
I’ve done this route in trail runners and in boots. For this specific walk, boots win. The scree on the descent from Cairn Toul and the loose boulders on the Lairig Ghru approach will destroy your ankles in trail runners. I wear the Scarpa Terra GTX (£200) — stiff enough for the scree, grippy enough for the wet granite slabs on the ridge, and broken in enough that I didn’t get blisters after 12 hours.
If you insist on trail runners, the Hoka Speedgoat 5 (£140) is the only shoe I’d trust, and even then, I’d be careful on the scree. The grip is excellent on wet rock, but the lack of ankle support means one slip on loose stones and you’re done.
Navigation: Don’t Trust Your Phone
I carry a Suunto Ambit 3 Peak (£150 used) with a downloaded GPS track of the route. The battery lasts 20 hours with GPS on. My phone goes in airplane mode and stays there. The Cairngorms have patchy signal at best, and you don’t want to be navigating by phone in a whiteout when the battery hits 20%.
I also carry a Silva compass and a 1:40,000 OS map. The map is waterproof paper. The compass is a basic Silva Expedition 4 (£30). I practice taking bearings before every trip. If you can’t take a bearing in 30 seconds with gloves on, practice until you can. The ridge between Angel’s Peak and Cairn Toul has no clear path in mist. You will need to navigate by bearing.
When NOT to Do This Walk (And What to Do Instead)
I’m going to be blunt. Do not do this walk if any of these are true:
- You haven’t done a 12-hour mountain day in the last 6 months
- You’ve never navigated in zero visibility
- Your waterproof jacket is older than 5 years and hasn’t been reproofed
- The wind forecast is above 40mph on the summits
- You’re planning to start after 9am in winter (daylight runs out at 3:30pm)
If any of these apply, do the Cairngorm plateau loop instead — park at the Ski Centre, take the funicular to Ptarmigan Station (runs May to October, £20 return), and walk the plateau to Ben Macdui and back. It’s 8 miles, less exposed, and gives you the same high-level experience without the commitment. You still get the views, the altitude, and the sense of being on top of Scotland. You just don’t get the ridge exposure or the 12-hour day.
Another alternative: walk the Lairig Ghru from north to south as a day hike. It’s 18 miles from the Ski Centre to the Linn of Dee, but it’s all valley walking. No scrambling, no exposure, and you can bail out at the bothy at Corrour if the weather turns. It’s a long day but not a dangerous one.
The most common failure mode on this route is underestimating the descent. People save all their energy for the summits and have nothing left for the 6-mile walk back to the car. I’ve seen people hitchhiking from the White Bridge car park because they couldn’t walk another step. If you’re not confident in your endurance, do the route in reverse — start with The Devil’s Point first, save Braeriach for the end. The climb is harder but the descent is shorter.
The Devil’s Point Descent: The Section Nobody Talks About
Every guide mentions the ridge. Nobody talks about the walk out. From the summit of The Devil’s Point, you drop down the south-east ridge to the valley floor. The first mile is steep grass and heather with no path. You’ll be sliding more than walking. Trekking poles make this section bearable. I use the Black Diamond Alpine Carbon Cork (£150) — they’re light enough to carry all day and strong enough to take my full weight when I slip.
Once you hit the valley floor, you pick up the Lairig Ghru path heading north. This is 5 miles of flat walking on boulders. By this point, your feet will hurt. The boulders are uneven and you’ll be stepping on them at awkward angles. I change into dry socks at the valley floor — the Darn Tough Micro Crew Cushion (£25) are my choice because they don’t bunch up in wet shoes. Fresh socks at hour 10 of a 12-hour walk is better than any painkiller.
The last mile to the car park is uphill. It’s only 300 feet of climb, but after 11 miles, it feels like 3,000. The path from the White Bridge junction back to the Ski Centre is a steady gradient on tarmac. I walk this section in a daze every time. The only thing that gets me through is knowing the pub at the ski centre does a proper pint and a plate of chips.
One final thing: leave a change of clothes in your car. You will be wet. You will be cold. Sitting in damp clothes for the drive back to Aviemore is miserable. I keep a dry fleece, jogging bottoms, and trainers in the boot. The 5 minutes it takes to change is the best 5 minutes of the day.
The Cairngorms ridge from Braeriach to The Devil’s Point is the best walk in Scotland that most people never attempt. It’s hard, exposed, and unforgiving of mistakes. But if you get it right — clear skies, steady wind, good navigation — it’s the kind of day that makes you understand why people keep coming back to these mountains. Just don’t underestimate the walk out.
