The narrowest ridge on the British mainland, located in the Scottish Highlands.

Aonach Eagach, 967 m

Grade 2/3 scramble / 9.5 km / 8 - 9 hours / 1100 m ↗

The ridge, east to west

  Height  
Am Bodach 943 m Munro Top — the downclimb off it is the first crux
Meall Dearg 952 m Munro. The last point with any escape at all
The Crazy Pinnacles — The narrowest and most serious section
Stob Coire Leith — Ridge eases
Sgorr nam Fiannaidh 967 m Munro, high point, and the start of the dangerous bit

Two separate cruxes. The downclimb off Am Bodach comes early and is, per the BMC, “for many people, the crux of the whole day” — awkward if you are not used to down-climbing, and there are anchors for a direct belay if anyone needs one. The Crazy Pinnacles are the real business: narrow, exceptionally exposed, and slow. Wikipedia notes “it is not uncommon for parties to take more than two hours to cross this short distance.”

Take the pinnacles direct. The BMC is explicit: “It’s best to approach the pinnacles directly rather than trying to edge your way around the side.” Same story as Liathach — skirting round them on loose ground beside the crest is not the easier option it looks like.

There is no way off

This is what makes the Aonach Eagach different from the other two ridges on this trip. It is not the hardest scrambling — An Teallach direct is harder — but it is by far the most committing.

There are no safe descents from the Aonach Eagach once embarked on this section of ridge; there have been many accidents to scramblers attempting to leave the ridge before the end of the scrambling. Walkhighlands

The BMC puts the boundary precisely: any attempt to escape between Meall Dearg and the west end “is asking for trouble — there are no safe descent routes to the south, and the northern options will leave you stranded a long way from civilisation.” North from Meall Dearg is possible but commits you to a long, rough walk out. Past that, the only retreat is back the way you came.

So the decision point is Meall Dearg. Weather, conditions and how the party is moving all have to be settled there, not later.

The descent is the dangerous part

More people come to grief getting off this hill than on it.

Do not attempt the descent along the rim of Clachaig Gully, which has an extremely eroded and very dangerous ‘path’, the scene of several fatalities. Walkhighlands

That path drops straight towards the Clachaig Inn and looks like the obvious way home, which is exactly the problem — it has a long accident record and features in UKH’s list of Scottish accident black spots. The steep southern slopes of Sgorr nam Fiannaidh down to Loch Achtriochtan are also best avoided.

Instead: continue west from Sgorr nam Fiannaidh, down to the bealach below the Pap of Glencoe, then the path to the road and Glencoe village. Bagging the Pap (Sgòrr na Ciche) on the way is the pleasant version and costs little.

Logistics

  • Start: small car park on the north side of the A82, about 300 m west of the house at Allt-na-reigh (NN174567). It fills early — there is a larger car park a short way further west.
  • Not a loop, and not a short walk back. Finishing over the Pap lands you in Glencoe village, roughly 2 km north of the Clachaig Inn and a long way down the glen from the car. Bus along the A82, or leave a second car in the village and start the day by riding back up.

Published figures vary with the finish taken — the page’s are Walkhighlands’:

Source Distance Ascent Time Grade
Walkhighlands 9.5 km 1100 m 8–9 h 2/3
Trail / LFTO 10.8 km 1200 m — 2
Steven Fallon 8 km 1200 m 6 h —

Notes

  • Grade varies by source: the BMC and Trail both say Grade 2; Walkhighlands says 2/3 and adds that it is “included in some climbing guides as a ‘Moderate’ rock climb” and is “probably the trickiest scrambling on any Walkhighlands route”. Walkhighlands’ visible 5/5 rating is a walk band, not a scramble grade.
  • Rope: worth having someone in the party who is confident with one. The anchors for a direct belay are there at the Am Bodach downclimb and on the pinnacles. Plenty of people solo it.
  • It is not a loop. We would need to take the bus back to the car (or to the start).
