Then follow the path south for 1.3 mi, climbing steadily from 80 ft to 780 ft. On the way you cross the Allt Cas Leac. It then turns south-east for 1.5 mi, climbing steeply from 780 ft to 2,300 ft. It then turns south-west for the last 0.8 mi to the summit, climbing steeply from 2,300 ft to 3,250 ft. The steepest part is between 2,100 ft and 2,850 ft, about 3.1 mi from the start. The summit is at 3,273 ft (998 m).

Common questions about Glas Bheinn Mhor
- How high is Glas Bheinn Mhor?
- Glas Bheinn Mhor is 3,273 ft (998 m), number 145 of the 282 Munros by height, in the West Highlands.
- How long does it take to climb Glas Bheinn Mhor?
- About 2 h 55 min up and 1 h 20 min back down by our route from Car park near Coileitir, before stops: 4.2 mi (6.7 km) each way with 3,173 ft (967 m) of climbing. That is about average for a Munro. Most people take longer than these estimates.
- Where do you park for Glas Bheinn Mhor?
- Our route starts at Car park near Coileitir.
- Can you climb Glas Bheinn Mhor without a car?
- The nearest railway station is Bridge of Orchy, 11 mi (18 km) from the start. Highland trains and buses are few, so check times on Traveline Scotland before you go.
- Is Glas Bheinn Mhor a hard Munro?
- By time and climbing, it is about average for a Munro, with 3,173 ft (967 m) of ascent over 4.2 mi (6.7 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.
- When is the best time to climb Glas Bheinn Mhor?
- 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.
A guide only. Mountain conditions change fast: carry a map and compass and know how to use them, and read the mountain forecast for the West Highlands before you go.
Questions
Where can I get a proper mountain forecast?
Read the Mountain Weather Information Service forecast for the West Highlands, 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. A computer picked the start as the car park with the quickest mapped way up, counting the climbing as well as the distance. Nobody has checked it on the hill yet, so it may not be the usual way up, and the path may be faint or missing on the ground. A line on a map is not a description of the ground.
- Path geometry: © OpenStreetMap contributors (ODbL), Overpass API extract fetched 2026-10-24T19:57:37.957Z. Start chosen automatically: the public car park on a public road with the shortest mapped-path route to the summit (busy roads and T4 paths weighted against).
- Elevation: Copernicus DEM GLO-30 (© DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018, provided under COPERNICUS by the European Union and ESA), sampled every 50 m, 3-sample median, 5 m hysteresis on ascent.

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 2 h 55 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. Glas Bheinn Mhor is hill 245 there.
