The gully that separates the North and Central buttresses of Stob Coire Nan Lochan in the Glencoe area of the Western Highlands of Scotland.
Get to Scotland first of course ! The Coire can reached from a car park on the A82 in the Pass of Glencoe at OS grid reference 168 569. The walk-in to the base of the buttresses takes about 2 1/2 to 3 hours - mostly uphill. For a full description of the various ways to get there read "Winter Climbs,Ben Nevis And Glencoe", a Cicerone Guide by Alan Kimber.
In good conditions this gully is a dream of a snow climb. Difficulties vary throughout the season, although it is relatively straightforward most of the time. It is also steep and very atmospheric. A great introductory gully, 155m at Scottish Winter Grade II - a two star classic. The views from the top of the climb, in all directions, are magnificent.
Although I have stated that the climb takes up most of the day, this includes the walk-in and walk-out. The climb itself takes only a couple of hours. Early in the season you will need to set out very early to ensure that you are back down before darkness sets in.
The usual basic winter rack plus two ice tools. Helmets are a must.
