The way up

From Coire Cas Car Park, follow the path south for 1.9 mi, climbing steeply from 2,050 ft to 3,600 ft. On the way you go over 1141m (NaN ft). It then turns south for the last 3.3 mi to the summit, climbing gently from 3,600 ft to 4,300 ft. On the way you go over Stob Coire an t-Sneachda (3,850 ft) and pass Lochan Buidhe on your left. The steepest part is between 2,900 ft and 3,700 ft, about 1.1 mi from the start. The summit is at 4,295 ft (1,309 m).

About Ben Macdui

In Gaelic
Beinn Mac Duibh
Means
MacDuff's mountain

Ben Macdui is the highest of the Cairngorms and, at 4,295 ft (1,309 m), the second highest mountain in the British Isles. It sits on the south-western edge of the Cairngorm plateau, above the Lairig Ghru to the west and Loch Etchachan to the east, on the old boundary of Aberdeenshire and Banffshire. It rises 3,117 ft (950 m) above the col that links it to higher ground, and its only higher Munro, Ben Nevis, is 53.7 miles away. Carn Etchachan and Sron Riach are its subsidiary Tops.

A barometer survey by the Rev Dr Keith in 1810 put it at about 4,300 ft, raising the question of whether it beat Ben Nevis. The Ordnance Survey built a trig point here in 1847, and the ruins of their Sappers' Bothy can still be seen. Queen Victoria climbed it on 7 October 1859. The mountaineer Norman Collie said he fled the summit after hearing footsteps.

The summit has a trig point on a large platform and a direction indicator put up by the Cairngorm Club of Aberdeen in 1925.

Common questions about Ben Macdui

How high is Ben Macdui?
Ben Macdui is 4,295 ft (1,309 m), number 2 of the 282 Munros by height, in the Cairngorms and Monadhliath.
How long does it take to climb Ben Macdui?
About 3 h 5 min up and 2 h back down by our route from Coire Cas Car Park, before stops: 5.4 mi (8.7 km) each way with 2,664 ft (812 m) of climbing. That is about average for a Munro. Most people take longer than these estimates.
Where do you park for Ben Macdui?
Our route starts at Coire Cas Car Park. There is a parking charge.
Can you climb Ben Macdui without a car?
The nearest railway station is Aviemore, 7.0 mi (11 km) from the start, and the nearest bus stop on the map is Cairngorm Ski Centre, 0.1 mi (0.2 km) from the start. Highland trains and buses are few, so check times on Traveline Scotland before you go.
Is Ben Macdui a hard Munro?
By time and climbing, it is about average for a Munro, with 2,664 ft (812 m) of ascent over 5.4 mi (8.7 km). Like every Munro it reaches over 3,000 ft, where the weather can be far worse than at the car park, so take a map and compass and check the mountain forecast.
What does Ben Macdui mean?
In Gaelic it is Beinn Mac Duibh. It is usually translated as "MacDuff's mountain".
When is the best time to climb Ben Macdui?
Daylight runs from about 18 hours in mid June to 7 hours in mid December, so summer gives the most time. From 1 July to 20 October it is the stag stalking season, when some estates ask walkers to keep to set routes. In winter, snow and ice turn most Munros into mountaineering terrain.

Questions

Where can I get a proper mountain forecast?

Read the Mountain Weather Information Service forecast for the Cairngorms and Monadhliath, written by forecasters for walkers and climbers. In winter, also read the Scottish Avalanche Information Service report for the area.

Where does the summit weather come from?

From MET Norway's forecast model, fetched for every Munro once an hour at the summit's own height. It is computer output for one point, not a forecast written for mountains, so treat it as a guide. The past hours are what the forecast said at the time. Wind chill, the freezing level and sunrise and sunset are worked out by this site from those figures; the freezing level assumes temperature drops steadily with height, so it can be well out when cold air sits in the glens.

How was this route drawn?

It follows footpaths and tracks mapped on OpenStreetMap, from a public car park to the summit, with heights from Copernicus elevation data. The start and the line were chosen by hand from the usual way up. A line on a map is not a description of the ground.

  • Path geometry: © OpenStreetMap contributors (ODbL), Overpass API extract fetched 2026-10-24T16:45:38.823Z, 21 OSM ways routed with Dijkstra (shortest distance; trunk/primary/secondary roads penalised so they are used only where no path exists).
  • Elevation: Copernicus DEM GLO-90 via the Open-Meteo Elevation API, sampled every 50 m, smoothed with a 5-sample rolling median; ascent/descent summed with a 5 m hysteresis band; the 90 m DEM also rounds off summits, so maxElevM can sit below the surveyed height.
  • Summit position: Database of British and Irish Hills v18 (CC BY 4.0).

Built 2026-10-24.

How is the time up worked out?

With Naismith's rule, the standard hill-walking estimate: an hour for every 3.1 miles (5 km), plus an hour for every 1,969 ft (600 m) of climbing, with no stops. For this route that gives about 3 h 5 min, one way. It ignores rough ground, weather, stops and the walk back down, so most people take longer.

Where do the car parks and bus stops come from?

From OpenStreetMap. Distances are straight lines, not the way you would walk or drive. A bus stop on the map says nothing about how often a bus calls: many Highland buses run a few times a day, some only on school days or by booking, so check Traveline Scotland first. The map cannot tell whether a car park is on a public road, so a remote one may only be reachable on foot or by train.

Where do the Gaelic names and stories come from?

From the hill's article on English Wikipedia and its Wikidata entry, put into a few words of our own. Meanings and pronunciations are only given where the article states them; many Gaelic hill names are old and their meaning is uncertain. Read the full article.

Where do the height and grid reference come from?

From the Database of British and Irish Hills, the surveyed list most baggers use. Ben Macdui is hill 518 there.
