Cir Mhor


Quick Facts
This is the height of the mountain above sea level. However, on the climb, it is the ascent that matters, i.e. the sum of all the uphill parts of the route.
799 m (2621 ft)

This is the standard notation used on Ordnance Survey Landranger maps.

Each reference consists of two letters identifying a 100,000 metre square block then three digits defining the Easting and finally the three digits defining the Northing with reference to the South West corner of the block.

NN166712 is the grid reference for the summit of Ben Nevis. Where you are given the map number ( For Ben Nevis = 41) it is acceptable to omit the two initial letters e.g. 166712. (Instructions on how to read the references are given on the OS maps).

Mountain names are usually in Gaelic, the native language of the Scottish Highlands, or have been derived from the old Scots and Norse languages. We give the most commonly accepted meaning, but accept that some of these are disputed.
Big Comb

The UK is covered by 204 Ordnance Survey Landranger 1:50,000 scale maps. Maps numbered 1 to 86 cover Scotland but for the highest mountains (Munros) only 23 maps are required. The name given roughly describes the area covered by the map.

A description of the characteristics of the mountain including any hazards of which you should be aware.

Arran's 4 Corbetts are sufficiently close to one another to be climbed together, but Goatfell is popular as a single peak and is described separately.

The three remaining peaks lie on a long winding ridge that starts with Beinn Nuis (792m) then goes N to Beinn Tarsuinn (Corbett), Cir Mhor (Corbett) and finally Caisteal Abhail (Corbett).

Cir Mhor is a more compact hill with three ridges, NNW to Caisteal Abhail, WSW to join the A Chir ridge of Beinn Tarsuinn and E to a bealach (The saddle). All three ridges are well served by paths, but the descent from Cir Mhor to the saddle is very steep and should not be attempted.

Hazards you may encounter on Cir Mhor include
 Unbridged River to cross.
 Steep slopes on or near ascent routes.
 Crags on or near ascent routes.
 Crags near summit.
General Considerations
 Temperature decreases by 1degree C for every 100m of ascent.
 Wind usually increases with altitude.
 Visibility can change markedly with cloud level.
 River/Stream levels can increase markedly in one day.

Reaching the summit of Cir Mhor is surprisingly easy given the steepness of the mountain on all sides. The east face may be a more commiting scramble but I was surprised to find that the western side gave easy access to the summit. It grass and bouldery terrain (although steep) to the top, and the final few metres are over granite slabs.

A good path leads from Glen Rosa and it has been built up with stone steps just below the col with A’ Chir. The approach from the Caisteal Abhail col is bouldery to begin with. Both routes combine for the final climb on steep grass. Near the top the route turns left along a path which contours across the slope then leads through rocks to the summit.
