1. Bealach na Bà: The Pass of the Cattle
Climbing from sea level at Tornapress to an elevation of 2,053 feet (626 meters) over just 5 miles, the Bealach na Bà is historically recognized as having the steepest ascent of any engineered road in the United Kingdom.
The pass cuts through the Applecross mountains via tight alpine hairpins reminiscent of continental cols. With gradients approaching 20% (1 in 5), low gear engagement is essential for both climbing and engine braking during descent to prevent hydraulic brake fluid boiling.
2. The B869 Drumbeg Road (Assynt Coigach Circuit)
Diverging from the main A837 route north of Lochinver, the B869 winds for 22 miles through the ancient Lewisian gneiss landscape of Assynt, terminating at the Kylesku Bridge.
The road is an undulating rollercoaster with blind summits, continuous off-camber curves, and sudden drops directly toward sea lochs. It passes the remote coastal communities of Clachtoll, Stoer, and Drumbeg. Sheep graze without boundary fencing across the tarmac, requiring cautious driving speeds rarely exceeding 25 mph.
- Passing Place Etiquette: Always yield to climbing vehicles. Do not cross the road to reach a passing place on your right; pull alongside it on the left.
- Allowing Overtaking: If a vehicle appears in your rear-view mirror, signal left and stop at the next passing place to permit faster local traffic to pass.
3. Glen Docherty & Kinlochewe (A832 Viewpoint)
Descending from the high moorland toward Kinlochewe, the Glen Docherty section of the A832 provides one of the grandest vistas in the Highlands. The road straightens as it drops into the glacial glen, framing Loch Maree and the rugged quartz mass of Slioch in the distance.

Essential Single-Track Regulations
Never park inside a passing place marked with diamond or square roadside signage. Passing places exist solely to facilitate flow and overtakes. Parking within them forces oncoming vehicles to reverse long distances on single-lane roads, creating serious bottlenecks and collision risks.
