An estimate of the time taken based on a derivation of Naismiths rules. Our calculation is based on the horizontal and ascent components of a climb, we do not make a reduction for descent.
Registered users can customise these walking times by specifying their own walking and ascending speeds. They can also add a fixed time period for stoppages.

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.
You can click on the map name to purchase the map for £6.29 including postage which is one of the cheapest prices we have found.
Our summary will always contain one of easy, moderate or hard to indicate the severity of the route.
Notes
Challenging long route with a bit of everything including steep slopes, scrambling on a narrow ridge and crossing an unbridged river.
Here we provide the nearest town to the start of the route where you will find basic services.
We then give directions from that location to the route start. Your approach route may differ.

Route Waypoint Map
The total ascent is 1,613 metres. Allow 6.5 hours to complete this 17.57 km route.
In winter months please check the local snow conditions at sais.gov.uk.
The hillphones service can inform you of stalking activities in the area.
Usually the shortest way to climb the mountain, making best use of tracks and paths to gain altitude. Route navigation requires map reading skills and an ability to navigate with a compass.
The information given here will enable you to annotate your map and plan your route. We do not give anecdotal descriptions on where to find the paths, worn by the feet of previous mountaineers.
Where the access routes are few or the ridge is narrow, paths are generally obvious. On open ground, following paths without using your compass may get you lost in poor visibility.

A selection of weather forecasts local to this route.
Retrospect of Sgurr na Ba Glaise from Rois-Bheinn. Getting very tired and pushing to beat declining daylight! (Descended W ridge of Rois-Bheinn - how do people have the energy to add An Stac to this walk??) 1st November 2008.
Rois-Bheinn's two tops (summit to left) seen across Coire na Cnamha. Taken from the west slopes of An Stac during descent to Alisary, 6th November 2010.
Like the idea of a more mobile base for your next Munro?
Fantastic, high quality, heated, 2-4 berth campervans for hire. The perfect winter base: freedom to choose where you go to get the most from the weather, & a cosy base to come back to after a great day on the hill! Big Tree Campervans – create your own adventure!

Patchy weather spoilt it ..
Approach paths boggy, hills nice. Druim Fiaclach ridge came out of
the cloud as was definitely the highlight!
Oh and there is a bridge over the river now although not needed
today as it was easily crossable.

I didn't use this route but one from another source which put me badly wrong in that a) it started from Glenshian Lodge and I had some difficulty in finding the path through the col and b) it went clockwise, which is fine, but on the descent from Seann Cruach I was directed too far W, struggling for a long time through tussocky grass and bracken at the end of what I can attest to being a Very Long Day. If you are making this descent go over the little 322m top to pt 3 of this route. Note that there is now a bridge over the Allt a'Bhuiridh about 200m downstream of the path's crossing point.

'Challenging long route' is accurate. I commenced the route in reverse, gained the lochan N of Druim Fiaclach, traversed over Sgurr na Ba Glaise to Rois-Bheinn then over W top and descended W ridge to Roshven where was met by car. The undulations of the ridge are steep and numerous, and under light snow (1st Nov 2008) that was as much in a day as I could have managed - hats off to anyone who can then go on to tackle An Stac! There is a recent landrover track running S into the coire above W bank of Allt a' Bhuiridh. Otherwise, trackless wilderness, a great rocky ridge and splendid views.
