Scottish Highlands in 2 Days:
Castles, Lochs & the Great Glen Circuit

The circuit from Edinburgh northward into the Scottish Highlands and back through the Great Glen is not simply a scenic drive — it is a passage through three distinct geological and cultural landscapes that bear almost no resemblance to one another. You leave the city through the broad green farmland of the Stirling plain, then the road narrows and darkens as you climb into Perthshire and the hills close in from both sides. By the time you reach Glencoe, the landscape has turned severe and primordial, the mountains pressing so close to the road that the pass feels almost like an enclosed space.

The route brings together the most visually extraordinary set of sites in mainland Scotland within a feasible two-day structure: Eilean Donan Castle — thirteen-century fortress on a tidal island where three sea lochs converge — sits at the western extreme of the circuit. Loch Ness, 23 miles long and containing more fresh water than all of England's lakes combined, occupies the Great Glen. Glenfinnan Viaduct carries a working railway across a Highland river valley in 21 stone arches. Each of these is extraordinary in isolation; the fact that they connect naturally into a single two-day loop makes this one of the most compelling overland journeys in Europe.

This guide covers the complete circuit in driving and tour order, with detailed notes on every stop, the best photography positions, where to eat along the route, what to pack for Highland weather, and how to decide whether a guided tour or a self-drive car hire suits your visit.

Leave Edinburgh as early as practicable — 6:30 AM gives you a substantial head start on the tour coaches that begin loading at 8:00 AM, and the A9 northward through Perthshire in early morning is a quiet road through spectacular Munro scenery. The route passes through Pitlochry, then climbs over the Drumochter Pass — at 1,484 feet the highest point on any main road in Britain — before descending toward the Great Glen at Dalwhinnie.

The A86 and then A87 west from Invergarry is one of Scotland's great drives: a narrow two-lane road that threads through a succession of glacial glens, past Loch Garry and Loch Cluanie, then descends through Glen Shiel toward the sea. The mountains here are of a different character from the rounded hills of the Cairngorms — steeper, more angular, the result of ancient volcanic intrusions into older schist and quartzite. When the road finally opens out at the head of Loch Duich and Eilean Donan Castle appears on its tidal island in front of a wall of mountains, it is one of the most visually powerful arrivals in Scottish travel.

Depart Fort William by 9:00 AM at the latest to reach Glenfinnan before the Jacobite steam train crosses the viaduct. The drive west on the A830 — known as the Road to the Isles — runs along the south shore of Loch Eil through increasingly spectacular scenery, reaching Glenfinnan at the head of Loch Shiel in approximately 45 minutes.

The Glenfinnan Viaduct is a Concrete Viaduct of 21 arches built between 1897 and 1901 for the West Highland line extension to Mallaig, designed by the engineer Robert McAlpine using mass concrete rather than masonry — one of the first large-scale concrete structures in Britain. It is 100 feet high at its tallest point and 1,248 feet long, curving in a gentle arc across the River Finnan. The viewpoint above the viaduct — reached by a 20-minute uphill path from the car park — is the most celebrated position in Scottish railway photography.

Return from Glenfinnan to Fort William and head south on the A82, which takes you through the entire length of Glencoe. The Pass of Glencoe is a glacially scoured valley of unusual severity — the mountains rise from 600 to over 3,000 feet on both sides, their faces largely unbroken by the gentler slopes that soften most Highland glens. The Three Sisters — three massive buttresses on the south wall of the valley — are particularly striking, and the road through the pass provides a series of extraordinary compositions as you drive south.

Glencoe carries history as well as geology. In February 1692, members of the MacDonald clan were murdered by government troops in what became known as the Glencoe Massacre — the killing of between 38 and 78 men, women and children by soldiers who had been billeted with the clan for twelve days under a code of hospitality. The event carries particular emotional resonance in Scotland because the breach of hospitality was considered as much an outrage as the killing itself. The National Trust for Scotland visitor centre at the southern end of the valley provides a thorough account of both the geology and the history.
