In reply to atrendall:
I'll second this guidebook. The above poster is the writer and we have been using it to research the ridge after cancelling our trip twice due to bad weather. We're up there hopefully this week but it's looking like a redivert down to Cornwall where the weather is better.
Adrian's guide has everything you could want to know on every section from watering points, nav help and bivi points. I get some like the idea of doing something without help but we don't have the time to keep hitting Skye so these types of guides are very helpful to get these things done safely in a visit.
