Touring the Scottish Highlands: Distances, Roads and Realism

The map lies about time

A Highland itinerary drawn in a hotel room usually assumes motorway arithmetic, and the Highlands do not work that way. North of Perth the A9 is a mixture of dual and single carriageway under average speed enforcement. West of the Great Glen most roads are single track with passing places, and progress depends on courtesy as much as engine.

A useful rule is to take whatever a mapping app estimates and add a third, then add stops. Nobody drives Glencoe without pulling over, and nobody should. Building an itinerary that assumes constant motion produces a day spent looking at the road rather than the country.

How single-track driving actually works

Passing places exist to let oncoming traffic through and to let faster vehicles overtake, not to park in. The convention is to pull into one on your left, or to stop opposite one on your right, and a lifted hand of thanks is standard. Local drivers, delivery vans and postal vehicles are working, not sightseeing, and letting them past costs nothing. Sheep and deer stand in the road with complete confidence, particularly at dawn and dusk. Cattle grids mark the edges of grazing land. Fords still exist on minor roads and can be impassable after rain.

• Pull in on the left, or stop opposite a passing place on the right
• Never park in a passing place, even briefly for a photograph
• Expect livestock on unfenced roads, especially early and late
• Some passes are unsuitable for long-wheelbase vehicles

Where the classic routes go

The standard first Highland trip runs north from Glasgow along Loch Lomond, over Rannoch Moor and through Glencoe, then either west to Fort William and the road to the isles at Mallaig, or north through the Great Glen past Loch Ness to Inverness. Eilean Donan sits on the Skye road and is the most photographed castle in the country for good reason.

Further west and north the character sharpens. Applecross is reached over the Bealach na Ba, a steep hairpin pass that is genuinely unsuitable for many vehicles and best avoided in poor visibility. Torridon and Assynt offer the most dramatic mountain forms in Britain and the emptiest roads.

Daylight, weather and midges

Latitude matters. Midsummer gives light late into the evening and a long touring day; midwinter gives a short window with sunrise late and darkness by mid-afternoon, which changes what an itinerary can contain. Snow closes high passes and the A9 can be affected in bad spells. Between roughly late May and September, midges are a genuine consideration at dusk near water and in still conditions. They do not affect driving but they affect how long anyone wants to stand at a viewpoint. Wind is the reliable cure.

Fuel, food and the gaps between them

Fuel stations thin out considerably away from the main corridors, and some close early or do not open on Sundays. Filling up when convenient rather than when necessary is standard Highland practice. The same applies to food: villages can be an hour apart and kitchens in remote hotels often stop serving earlier than visitors expect. Mobile coverage is patchy in glens and on the west coast, which matters for coordinating a pickup. Agreeing a time and a place before separating is more reliable than assuming a message will get through.

How many days it really needs

A day trip from Edinburgh or Glasgow reaches Loch Lomond, the Trossachs or Stirling comfortably, and Glencoe at a stretch. Two days opens Fort William, Glenfinnan and the Great Glen. Skye and the north west coast want three days minimum to be anything other than a drive. Being driven changes the calculation, because the passenger seat is where the scenery is. On roads this demanding, the person at the wheel sees a fraction of what everyone else does.
