The hill

Bidein a' Ghlas Thuill is the higher of An Teallach's two Munros, standing above Dundonnell and Little Loch Broom.

Its partner, Sgurr Fiona, is under a kilometre to the south-west.

The Dundonnell Mountain Rescue Team describes An Teallach as a high and complex ridge, with at least ten summits over 700 metres and three over 1,000. Its pinnacles are carved from Torridonian sandstone, and the British Mountaineering Council counts this summit the high point of a day on the ridge.

Mountaineering Scotland and the Outdoor Access Trust for Scotland began their path campaign here. They raised £315,000 to rebuild more than three kilometres of eroded path, and the work was finished in March 2026, two months ahead of schedule.

Starts from
Dundonnell, where the rebuilt path begins.
Scrambling
The traverse of An Teallach requires some stretches of scrambling, and the British Mountaineering Council grades it a solid Grade 3 when taken directly. Read the route, and the rescue team's and Mountaineering Scotland's pages below, before deciding.
How long
Climb Torridon, a guiding company, gives about 6 to 8 hours for its guided day to the two Munros from Dundonnell.
Under snow
There is no avalanche forecast for this hill, but that does not mean there is no risk under snow. The British Mountaineering Council calls winter a complete game changer on the ridge: in full winter conditions it is a full on grade II winter traverse.
The ground
Privately owned, and a Site of Special Scientific Interest. Do not take the absence of a notice to mean there is no stalking.
Summit
Grid reference NH 068 843
Parking
The Dundonnell Hotel has paid day parking for non-residents.
Toilets and food
Do not count on a public toilet at Dundonnell: Highland Council lists none there. Our nearest places are in Ullapool.

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 068 843
  • 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.
