Any mountains south of those accessible from Glen Carron, such as Glen Strathfarrar, Glen Cannich Glen Affric, Skye, Glen Shiel, and any mountains south of there, bounded to the east by the Great Glen.
Coire Lagan may not feature highly on many people's list of ski destinations, but in the right conditions, there's potential for a bit of skiing here. Despite the proximity of the sea, good conditions do exist. In order to time a successful visit, you will need to keep a close eye on weather patterns, maybe get a little local knowledge, and have a bit of luck on your side. If things really are going your way, then you may not have to pick bits of gabbro out of your bases after a ski!
The North facing corries of the South Cluanie Ridge are a fine sight from the A87 in Glen Shiel. Many of the corries have some great looking lines on show, and there are a few hidden away from view as well. However, the eye is naturally drawn to the pyramid of Sgùrr an Lochain towards the Western end of the ridge, and the fine looking East face. Offering a superb descent off of a pointy summit, it doesn't get much better than this!
