Questions
Where can I get a proper mountain forecast?
Read the Mountain Weather Information Service forecast for the Southeastern 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 2026-10-24T19:58:18.650Z. 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.
Where do the height and grid reference come from?
From the Database of British and Irish Hills, the surveyed list most baggers use. Carn an t-Sagairt Mor is hill 465 there.
