A82 through Glencoe

The 22-mile single-track Wee Mad Road of Sutherland threads blind hairpins and tight passing places past Assynt sea lochs, white beaches and ancient Lewisian gneiss, making it the most technically challenging public road in Scotland.

Britain's steepest road climb rises to 626m with Alpine hairpin bends and no-guardrail exposure, making the 11-mile single-track pass over the Applecross Peninsula one of the most exhilarating and challenging drives in the UK.

This 12-mile dead-end single track descends from the A82 at Buachaille Etive Mòr deep into a spectacular Highlands glen made famous as the Skyfall location in Bond, ending at a lonely pier on Loch Etive.

Scotland's Route 66 loops 516 miles around the northern Highlands from Inverness, delivering an unrivalled mix of coastal drama, sandy beaches, mountain passes and remote fishing villages.

The 90-mile Cairngorms loop climbs the highest and most snow-prone public roads in Britain—the Cairnwell and Lecht passes—delivering dramatic Highland landscapes, Royal Deeside castles and whisky-country villages between Blairgowrie and Grantown-on-Spey.
