Sgurr nan Eag, Sgurr Dubh Mor & Sgurr Sgumain
17th August 2004 & 4th November 2008

Route 17/08/04: Ascent 1350m = 4500'; 9 miles; 8 hrs.
Route 4/11/08: Ascent 1270m = 4175'; 7⅔ miles; 9 hrs.

Coire Lagan from above Glen Brittle camp site. Caisteal a' Garbh-choire from Loch Coir a' Ghrunnda Gars-bheinn from Sgurr nan Eag Sgurr Dubh Mor from Sgurr Dubh an Da Bheinn Gars-bheinn from Sgurr Dubh an Da Bheinn Sgurr Alasdair from Sgurr Dubh an Da Bheinn. Sgurr Alasdair with Bad Step in foreground Sgurr Mhic Choinnich from Sgurr Sgumain showing Collie's Ledge Sgurr Dearg showing path up from An Stac Screes

Access: The very useful bus used to reach Glen Brittle no longer runs.
Map: By far the best map to use for the Cuillin is the 1:12500 scale Harvey's Superwalker map, "Skye: The Cuillin". The Ordnance Survey 1:25000 map suffers in clarity from too much heavy shading for cliffs.
Route: There are several route choices to make regarding ascent to and descent from the main ridge. Some of them illustrated by the two versions below, including comments on some poor choices I made! The GPX file above gives the best route up Sgurr nan Eag and chooses a descent from Bealach Coir a' Ghrunnda to Loch Coir a' Ghrunnda. There is an alternative descent from Bealach Coir a' Ghrunnda west down the Sgumain Stone Shoot to the southern of the two paths crossing Coire Lagan. Further detail and useful GPX files are given here for a similar walk.
As the ridge is consistently above 800m, it is easily possible to add in Sgurr Sgumain and/or Sgurr Alasdair to an ascent of Sgurr nan Eag and the “two Dubhs”. There are sufficiently many different paths to avoid most difficulties. However, I could see no safe way passed the Mauvais Pas between Sgurr Sgumain and Sgurr Alasdair and was consequently unable to add both of these summits to the walk in the time available.
Many of the valley paths are now properly built and maintained. Currently (May 2017), the upper path below Sron na Ciche is the better constructed. The times below predate this construction phase when the paths in Coir' a' Ghrunnda were rather slow. When dry, most ridge paths are easy to follow by observing where the rock face is scratched by crampons, where the rocks are whiter, and where rocks have been broken into smaller pieces. In cloud or damp conditions, time can often be wasted looking for a safe route. As elsewhere in the Cuillins, it is rock underfoot all the way, and so hard on joints.
