I am in the process of writing up a report for the same walk from Sunday, not quite as good as yours... but still beautiful
Here is a sneak peak of Todd leading us out over the ridge
Incidentally, I avoided the tourist route on the way down by heading off to the Munro Top (Carn Dearg??) - there are then the makings of a path over the rocks down to the lochan, skirting around the top of the Castle. Not to be recommended in bad weather!!
