That’s what the publicity machine tells us, but does it really hold up? And is it as scenic once you are away from the rails? Well, the answer to both questions is a resounding “YES!” - The signs at the stations along the line tell of “72 miles of scenic splendour”, but that barely does it justice.

And its location halfway along the Lairig Leacach means it has another attribute that every fine mountain needs: a fantastic walk in. Heading out from Spean Bridge station, on the West Highland Line, I trudged along the road by the River Spean, gurgling impressively in nearly full spate.

These two mountains, which guard the easterly edge of the peninsular, offer a tantalising glimpse of what lies beyond. During the intervening years I have probably added in a few wisps of cloud to the image, and deepened the hue of the colours. But the sensation was clear: I knew I had to return and explore the land beyond those hills.
