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.
1234 m (4048 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).

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

Aonach Beag and Aonach Mor are the two highest peaks on a long ridge running N-S from the Great Glen to the head of Glen Nevis. The sides of this ridge are generally steep and craggy and it is best to assume that you should only attempt an ascent or descent from the N or S ends of the ridge.

As the N slopes of Aonach Mor are developed for skiing, it is normal to ascend both these mountains from the S via Sgurr a'Bhuic.

An alternative route leads up Coire Giubhsachan to a high col (830m) between Aonach Beag and Carn Mor Dearg. Whilst an ascent of this path is relatively easy, it can be difficult to locate when descending and any deviation will lead you to dangerous crags. If in doubt avoid this route.

Hazards you may encounter on Aonach Beag [Nevis region] include
 Crags on or near ascent routes.
 Crags within 1km of 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.

Take care to locate the correct point to begin the descent down from the summit plateau to the bealach between the Aonach summit plateau and Carn Mor Dearg. Do not descend from the lowest point. The top of the preferred route is marked by a small cairn, well offset from the direct path between the two summits. Best found by walking along the west edge of the plateau but take extreme care in poor visibiity. Even that route is trcky, being steep and with a lot of loose surfaces.

When descending Aonach Beag to get to Sgurr Choinich Mor, first follow the ridge south west, than when you see the main path go south east go to the corner and find a very steep winding path twisting itself down the craggy slope. We descended with a heavy overnight but please realise that this descend is not for the inexperienced.

Did these from the gondola station. Slight cheat but then gives access to a much less travelled route onto Carn Mor Dearg allowing all 4000ft'rs in lochaber to be reached in a day. Although you do have a tricky westward descent from the bealach between Mor & Beag .... not fun in good weather never mind bad!

Completed both Aonach Beag/Mor from the apparent less favoured route from Coire Giubhsachan. The path up the west slopes, although steep, was fairly easy going. Once onto easier slopes, the summit of Aonach Mor is 3/4km on a 12degree bearing. The ascent from the bhealaich between these two mountains is very narrow, but once the cloud base lifted, the views all round are spectacular. A very rewarding days hillwalking.

Completed on a beautiful spring day in May 2002 (with Aonach Mor). Superb 360 panorama, one of the best. Dont descend from the bealach between Beag and Mor...its very risky.
