When do the Highlands actually reward you?
June to August for light, May and late September for comfort. Midsummer here gives daylight that lasts well past ten at night, which is what makes a long touring day possible; it also coincides with midge season, which builds from late May, peaks in July and August, and is worst on the west coast in still, humid, overcast air. Midges will not fly in wind above about 10 km/h (6 mph), in rain, in bright sun, or below 12°C, so a breezy ridge is a different experience from a sheltered loch shore on the same afternoon. May and the second half of September are the compromise months: long enough days, almost no midges, and the glens turning russet at the later end.
Which dates cannot be moved?
The sporting ones. Red deer stags are stalked from 1 July to 20 October, with the season really beginning in August; grouse open on the Glorious Twelfth of August and run to 10 December. Those dates set the calendar on a sporting estate, along with the availability of experienced ghillies, and they are the reason a Highland week built around the sporting life cannot simply be shifted a fortnight. Fishing is arranged around river conditions rather than statute, which means it is the one element we never promise in advance.
Where should you base, and for how many nights?
Four or five nights, in one or at most two places. Inverness and the Speyside whisky country make the eastern base; Fort William, Glencoe and the Isle of Skye make the western one, with the more dramatic scenery and the slower roads. A country-house hotel or a private estate taken in full is the fitting shape here, and a castle or estate with exclusive use is what we hold most often. Four nights lets the distances be absorbed; three turns the trip into repacking.
Car, train, or the train?
A private driver-guide, with one great rail journey taken deliberately. The West Highland Line to Fort William and Mallaig is worth doing for its own sake, but sights here are far apart and public transport is thin, so a chauffeured vehicle is what lets you stop for the distillery, the loch and the light. The Royal Scotsman is the third option and a different proposition: 36 guests out of Edinburgh, two to seven nights between April and October, from about £4,500 per person for two nights, inclusive of cabin, all meals, all drinks, excursions and entertainment — see our guide to Europe's luxury trains.
What should you not expect?
Reliable weather, and short drives. The Highlands are unpredictable in every season; a settled forecast is a suggestion, not a plan, which is why we build in alternates rather than a fixed daily schedule. Roads west of Fort William are frequently single-track with passing places, and three hours between two points on a map is normal.
Who should not come here?
Anyone who needs certainty, and anyone who wants to see Scotland in three days. This is the natural finale to a Scottish journey, reached after Edinburgh or Glasgow, not a standalone long weekend — and from around US$1,350 per person per night it is not the place to discover that you dislike rain, insects and driving. If that describes the party, the answer is a city week instead.
