The Bealach na Bà — "pass of the cattle" — was a drovers' route long before it was a road. The single-track road built over it in 1822 climbs from sea level at Applecross to around 626 metres in roughly six kilometres, with gradients approaching 20% and tight hairpins on the eastern side that look as if they belong in the Alps. It is the greatest ascent of any road climb in the United Kingdom.
At the top there is a car park and viewpoint; on a clear day the view west takes in Raasay and the mountains of Skye. It's unsuitable for very large vehicles and learner drivers and is often closed by snow in winter, when the coast road via Shieldaig is the alternative.
