Ben Oss

Munro
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.
Altitude
1029 m (3375 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.

  Description
Ben Oss and Beinn Dubhcraig form a curved ridge around Loch Oss and are generally climbed together. Ben Oss has craggy sections and many rocky outcrops, particularly on its N face overlooking Glen Cononish.

Ben Oss is usually accessed from Glen Cononish to the N via Beinn Dubhcraig, although an approach could be be made from Gleann nan Caorann in the S.

Ben Oss's two N ridges are craggy and generally avoided as they are steep and rocky therefore the best alternative descent is S then SW to Creag Dubh a' Bealach where Ben Oss meets the lower slopes of Ben Lui and descend NNW through Coire Laoigh to Glen Cononish.

Hazards you may encounter on Ben Oss include
 Stony/rocky 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.

Completed Dubhcraig a few weeks ago indeep snow so ran out of time for Ben Oss.Revisist to Dalrigh and on to Alt Coirie Dubhcraig after the sharp right turn over the rail bridge.This is the start of a very long, very wet approach through the pretty woodlands.Nice waterfalls help to forget the sodden underfoot conditions.Took to the SW ridge of Dubhcriag where you have some stunning views of Ben Lui and target of the day. Ben Oss.There is a very large drop "Col" between the 2 hills with South path to right of the large Lochan.Heading back North and directly up by any means takes you to a steep rocky section and on to the summit.Continued North wards and back to the large drop.The only way back if you are going to Dalrigh is to re ascend Dubhcraig on the obvious path.Do not continue North as it leads to dangerous crags with sheer drops! Demanding day but worth it for those views of Ben Lui.

A long approach from the end of the track beyond Cononish. The east bank of Allt Coire Laoigh was straightforward after a dry spell. If approaching from Beinn Dubhcraig, there is a tempting path from the col with Ben Oss which veers off to the left; it is not helpful and it is better to aim for higher ground directly. Descending the north ridge of Beinn Dubhcraig we strayed too near Creag Bhocan and overshot the usual very muddy route. This was not a problem: although not on a path we were at least on dry ground.

Climbed this with its neighbour Dubhcraig on 19/2/06. Took the longer route along vehicle track in Glen Cononish towards Ben Lui - wonderful views of the snow clad NE corrie and ridges. 7.5km but easy walk to start the day. Followed the gorgeous glacial valley of Allt Coiire Laoigh - many stream gullies to be crossed but got into a rhythm of holding the contour line round each. Snow & crampons from below the bealach onwards. Retraced steps off Dubhchraig for 250m then NNW, down and N in straight line to bridge at Cononish. Back down track to Dalrigh. 13 miles,tiring but great & not muddy!

The start is the most awkward aspect of this Munro. After crossing the railway and passing through the gate turn directly to the right and follow the boggy path to the footbridge over the river (do not follow the farm track as it's a long detour). Head up through the forest (boggy) and over the two deer fences and stiles and onto the path proper. The ascent of Dubhcraig is straightforward followed by a descent and then ascent of Oss. Unfortunately it's a reascent of Dubhcraig to pick up the path back to the car park. A long slog of a hill with boggy ground on many stretches.
