Bealach na Bà: Britain's most un-British climb

Most British climbs are honest about what they are. They go up a hill, they hurt for ten minutes, and then they stop. Bealach na Bà does something else. It behaves like an alpine pass that got lost and washed up in Wester Ross, and the first time you see the sign at the bottom — the one warning learner drivers to turn around — you understand that the next hour is going to be different.

The shape of it

The climb starts at Tornapress, at the head of Loch Kishorn, essentially at sea level. It ends at 626 metres. In between there are roughly nine kilometres of road, which gives an average of just under seven percent.

That average lies, as averages on this climb always do. The opening kilometres are gentle enough that you can convince yourself it will be fine. The road tracks up a glen with the gradient sitting somewhere in the low single digits, and the climbing that matters has not started. Then the valley closes in, the road turns to face the headwall, and the last stretch before the summit throws a set of genuine hairpins at you with gradients that touch twenty percent on the inside lines.

It is the only road in Britain built to that shape. That is not a figure of speech — the hairpins are the reason people ride here rather than at any of the dozen steeper climbs in Scotland.

Single track, passing places, and what that actually means

The road is single track with passing places for most of its length. On a bike this is mostly a gift: there is no shoulder to be pushed into, and traffic moves at a speed that assumes it will have to stop.

It is also the thing that catches people out. A passing place is not a layby. Stopping in one to take a photograph while a camper van comes round the bend below you is how the climb gets its reputation for being unfriendly, and it is worth knowing before you go that the etiquette matters more here than the gradient does.

The descent to Applecross on the far side is the reward, and it is a better descent than it is a climb — open, fast, with the Cuillin ridge of Skye across the water on a clear day. On a day that is not clear you will see approximately none of this, which is the honest Scottish caveat attached to every sentence in this article.

When to go

May and September are the usual answers, and they are the right ones. June through August brings midges to the lower slopes and camper vans to the road in numbers the passing places were not designed for. Winter closes the pass often enough that it is not worth planning around.

The weather does what it wants regardless. The summit sits high enough and close enough to the Atlantic that it can be twelve degrees and still at Tornapress and four degrees with horizontal rain at the top, in the same hour. Pack for the top, not for the bottom.

Why it looks the way it does on a wall

Drawn as a single line, most climbs are a slightly wobbly diagonal. There is not much to look at, because there is not much shape to a road that goes up a valley.

Bealach na Bà is one of the exceptions. The hairpins near the summit put a tight, deliberate knot at one end of an otherwise long approach, and that asymmetry is what makes it read as a specific place rather than a generic squiggle. It is the same reason Alpe d'Huez works as a motif and the reason a flat time trial course does not.

If you have ridden it, you will recognise the knot before you read the label. That is more or less the whole test.
