Driving tour of Scotland
Itinerary

The Driving tour of Scotland is in the United Kingdom. It would take about two days to drive this route non-stop, but it would be best to allow 7 - 10 days to have a relaxed tour, seeing the sights on the way.
Understand
One way of looking at Scotland is to think of it as divided in two parts: the first is the Highlands whereas the second is known as the Lowlands and contains the industrial heartland. Traditionally the Highlanders spoke Gaelic while the Lowlanders spoke Scots. The "central belt" cities of Glasgow and Edinburgh house the vast majority of Scotland's population. They're worth a visit for their culture, architecture and history. Heading up into the Highlands there are relatively few people, small villages, just the occasional town, and great sights to enjoy.
Prepare
General Rainy days and midges are the main threats to your visit. Both are annoying rather than dangerous - the small flies don't carry diseases but will bite you leaving an itchy spot for a few days. The rain is what makes the landscape so lush and green, so try to be philosophical about it! It is best to plan your stops in advance, as there are limited places to sleep in some locations, and it would be best to book accommodation a month or two in advance.
Roads and Bridges Most arterial roads in Scotland are bidirectional. However, many country roads remain to be narrow, single-track roads. It is highly advisable that people not used to driving on single-track roads do not learn to do so on dangerous roads in busy tourist hotspots. Single-track roads have many "passing-places" where you can wait for oncoming traffic to pass, or they can wait for you to pass. Be considerate to other drivers, and decide whether it will be easier for you to move into a passing-place or for them to do so. Many of the bridges on the A82 around Rannoch Moor are narrow. The road is mostly 7 metres wide but the bridges tend to be a fraction of this. Many drivers lose wing-mirrors from minor collisions of the wing-mirrors of adjacent cars. Therefore, when crossing the bridges don't move too far into the middle or you will lose your expensive wing-mirror. The A82 becomes quite frightening between Tarbet and Ardlui, so be cautious and be comforted that this is one of the worst parts of the journey - you won't encounter anything as bad as this again as long as you stay on the main road.
Hillwalking When walking in the Highlands, be vigilant as there are many bogs and marshes which you may accidentally step in and get stuck in. Wear wellies and preferably carry a hiking pole. Don't stray from the road too far, and never stray from the main path unless there is a bog in your way.
Get in
This itinerary starts in Glasgow, so the directions below are for this city, however, you could start anywhere along the journey, so see the individual Wikivoyage guides for these places for information on how to get there.
By car From England, take the M6, then the A74(M) and M74 (from Birmingham) or the A1/A1(M), then the M8 and A8 (from London) to get into the Glasgow.
By plane There are airports throughout Scotland, and 1 Glasgow Airport (GLA IATA) has regular international flights. However, nearby 2 Edinburgh Airport (EDI IATA) is the busiest in Scotland, again with regular international flights. There are also other airports in Scotland, with services from international destinations or England:
3 Aberdeen Airport (ABZ IATA). 4 Glasgow Prestwick Airport (PIK IATA). mainly serving Spain and Italy. 5 Inverness Airport (INV IATA).
By train Wikivoyage has a guide to Rail travel in Great Britain The East Coast Mainline comes from London King's Cross to 6 Edinburgh Waverley, with trains running throughout the day. Getting from Edinburgh to Glasgow is easy, as there are many trains running regularly. There are also trains which run from London Euston to 7 Glasgow Central.
Drive
From 1 Glasgow head north-west up the A82 towards Fort William, along the side of 2 Loch Lomond. At the visitor centre at 3 Balloch admire the view down the loch. Stop at 4 Luss, a small honeypot village with a pleasant pier you can walk out over. At Tarbet, slow down and take the sharp right-hand turn to continue North on the A82. If you continue round with the current road, you will be on the A83. The road from here to Ardlui is extremely winding, narrow in places and often hangs out over the loch so be cautious. At 5 Inveruglas, just after the hydro-electric pipelines, park up for more loch views. Just beyond 6 Crianlarich, at 7 Tyndrum stop and try your hand at gold panning. Tyndrum is an excellent place to stop off and get a coffee, something to eat and to go to the toilet. After 8 Bridge of Orchy, the A82 heads out across 9 Rannoch Moor, one of western Europe's largest remaining wilderness. Barren, spectacular landscapes! Just before Glencoe, you can take a left into Glen Etive - famous for its portrayal in many films and TV series. This road is single-track, so continue on past to Glencoe if you don't feel comfortable with single-track road. The road descends into 10 Glencoe. Admire the waterfalls at the Meeting of Three Waters. Admire the stone bridges on General Wade's military road. And more than all of these, admire the skyline above - a line of mountains to the left, and to the right the snaky spine of the Aonach Eagach ridge. Finally, at the bottom of the glen, stop and look out across the loch at mist-covered islets. From 11 Fort William you can climb 12 Ben Nevis, the highest peak in the UK. Take the Road to the Isles, the A830, to the 13 Glenfinnan Monument - an atmospheric spot at sunset. Optionally carry on to 14 Arisaig (interesting museum), view the 15 White Sands of Morar, or visit the port at 16 Mallaig, with options to continue on ferries to the islands, including the 17 Small Isles. Backtrack to the A82 and take the A87 to 18 Kyle of Lochalsh. Cross the bridge to the 19 Isle of Skye for a tour of the island. Head north to 20 Torridon and walk some of the fine mountain paths here. Head north via 21 Gairloch and 22 Poolewe, maybe stop off a
Stay safe
Other than basic precautions like locking your car and not leaving items in view, the Scottish Highlands are safe and friendly.
