You know, William, I don't have nearly such a downer on the Loch Arkaig road as some of the others here.

I've walked it twice - on my first Challenge in 2000 (when it was the route on my route card), and after getting trapped by the weather at Oban bothy in 2012 (when I had diverted through Glen Pean and had no real alternative).

Yes, it's a road ... but as roads go, I don't think they come much better for walking.
