Sgairneach Mhor

A Munro of 991 metres, number 155 of the 282.

The hill

Sgairneach Mhor stands on the west side of the A9 at Drumochter, the only one of the four Munros there that lies wholly in Perth and Kinross.

Beinn Udlamain is its nearest neighbour, about two kilometres to the west, and A' Mharconaich stands about three kilometres to the north.

Ben Alder Estate counts it among the nine Munros on its ground, along with Beinn Udlamain.

Nearest start
Transport Scotland's 2016 note on walkers' routes names the Drumochter Pass lay-bys on the A9 for Beinn Udlamain beside it, and records that walkers for these hills cross the A9 on the level.
The ground
Sgairneach Mhor is one of the nine Munros on Ben Alder Estate. Check for stalking before you go and follow any signs.
Under snow
There is no avalanche forecast for the Drumochter hills: the Scottish Avalanche Information Service forecasts for six other areas. Having no forecast does not mean there is no risk under snow.
Summit
Grid reference NN 598 731.
Roadworks
In October 2026 overnight resurfacing on the A9 at the Pass of Drumochter was due to finish by the morning of Tuesday 13 October, with temporary traffic lights, a lane closed during working hours and lay-by 83 shut. More works follow, so check Traffic Scotland on the day you travel.
Fuel and toilets
The Dalwhinnie Service Station has 24-hour fuel and a toilet.

Taking on Munros, while fun, is serious.Ben Alder Estate, which lists the hill among its Munros
Before you go

Carry

  • A paper map and a compass, and the skill to use them
  • Waterproofs, warm layers, hat and gloves
  • Food and drink
  • A head torch, a whistle and a first aid kit
  • A survival bag
  • Boots with a good grip

Under snow and ice this is a different day, with short light and the risk of avalanche. It needs an ice axe, crampons, winter boots and the skill to use them.

If something goes wrong

  • Dial 999, ask for the police, then mountain rescue
  • Give a six-figure grid reference: the summit is NN 598 731
  • Say how many are hurt, how many are with you, and your number
  • Register to text 999 before the day: text the word register to 999

The summit is optional. Turning back is the right decision whenever the cloud, the wind or the light say so.
