The hill

Sgurr nan Ceathramhnan stands at the head of Glen Affric, on the north side of the glen.

It is number 23 of the 282 Munros by height, and higher than every one of its nearest neighbours: An Socach, Mullach na Dheiragain, A' Ghlas-bheinn and Beinn Fhada.

The Affric and Kintail deer management plan of 2017 puts it on the march, the boundary where the North Affric Estate meets the National Trust for Scotland's West Affric ground.

The name is also spelt Ceathreamhnan, the form the Met Office uses.

The road end
Forestry and Land Scotland's River Affric car park, at the end of the public road, is its starting point for longer routes into the mountains. It is a long way from this hill.
On the hill
There is no mobile signal, so it is hard to call for help if you get into difficulties. Forestry and Land Scotland says you need to be fit, confident at map-reading and navigation, and well equipped with clothing and food.
Burns
On the north side of Loch Affric, Forestry and Land Scotland's circuit crosses burns with no bridges, and they can be tricky after heavy rain.
The ground
The Affric and Kintail deer management plan of 2017 counts Sgurr nan Ceathreamhnan among the Munros on the North Affric Estate's boundary with the National Trust for Scotland's West Affric: no access issues, but walkers are encouraged to stick to the ridges. Things may have changed since 2017, so read Mountaineering Scotland's page on stalking before you go and follow any signs.
Under snow
There is no avalanche forecast for this hill, but that does not mean there is no risk under snow. The Scottish Avalanche Information Service's full winter forecasts for its six areas begin on 17 December 2026.
Car parks
Forestry and Land Scotland runs three car parks on the glen road from Cannich: Dog Falls, Loch Beinn a' Mheadhain at about 8 miles, and River Affric at about 10 miles, where the public road ends. In 2026 parking cost £2 for up to 1 hour, £3 for up to 3 hours and £5 for the day, on one ticket for all its Glen Affric sites; Blue Badge holders park free. You may park overnight at all three for the hills but not camp or sleep in your vehicle.
The road and the bus
Much of the glen road is single track. Buses run from Inverness to Tomich and Cannich all year, and Traveline Scotland has the times, but they reach the villages, not the car park about 10 miles on.
Toilets and food
The toilets at Dog Falls are open all year, those at River Affric from 1 April to 31 October. There are no cafés or shops in the glen: eat in Cannich or Tomich, and there is a shop in Cannich.

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 NH 057 228
  • 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.
