Sgurr nan Coireachan & Sgurr Thuilm, map 40
18th October 2005 & 28th May 2010

Route: 1455m = 4775' ascent; 13.4 miles; 7 hrs.

Access: From Fort William, take A830 W to Glenfinnan. Note that there may be game hunting here, so access to some parts may be restricted. Walkers should observe the notices and keep to the ridge paths. A bike would be excellent to cover the 3 miles each way of the walk in and out as the road to Corryhully is tarmacked as far as the lodge. (It is driveable, but may be private.)
With effort, it is possible to add the Corbett Streap into this walk. Steve Fallon gives a route here under "Alternative Routes". There's a video of it here. This addition would be too steep as well as too strenuous for most, and I've not attempted it.
Terrain: Mostly clear, typical ridge paths throughout, but deteriorates slowly on the way round, finishing in a wet peaty descent path off the ridge.
Weather 18/10/05: 12°C at car, tops clear, no rain, bright but no sun & total, light cloud cover.
Weather 28/5/10: 4°C at car at start; sunny intervals, mostly overcast; showery all day, light snow showers am, a heavy shower early pm. In cloud on Sgurr nan Coireachan, else below clouds.
Mobile: Orange available in Glenfinnan and on both Munro summits.
