A pilot scheme from the Scottish Government has capped single bus fares at £2 on participating routes across the Highlands and Islands, extending to the Strathclyde region in September. It now stretches from Shetland and Skye down to Glasgow and South Ayrshire, with a nationwide rollout planned. For travellers, that means some of Britain's most scenic drives are suddenly available for less than a coffee — without the hassle of driving single-track roads yourself.

The savings are dramatic on long hauls. The Stagecoach X99 from Inverness to Scrabster covers 177km of peatland and Atlantic coast and would normally cost £31 single. En route you can hop off near Dunrobin Castle, a turreted Loire-style chateau, or at Whaligoe, where 300 flagstone steps drop between cliffs to a former fishing harbour.

Whisky fans have obvious reasons to celebrate. The number 36 between Dufftown and Elgin threads through Speyside country past Glenfiddich, The Balvenie, Glen Moray, Speyburn and Craigellachie — and nobody has to play designated driver. On Islay, the 451 links Port Ellen's trio of Laphroaig, Lagavulin and Ardbeg with Bowmore and Port Askaig, where Caol Ila is a steep half-hour walk away; a five-minute ferry plus the 456 bus adds Jura's distillery.

Movie magic comes cheap too. Shiel Buses' 500 from Fort William to Mallaig passes the Harry Potter-famous Glenfinnan Viaduct, where a steam train return costs £76 — the bus gets you the arches, the 60ft Jacobite monument and walks to the Silver Sands of Morar for pocket change. Route 44 from Fort William to Kinlochleven delivers Skyfall-style Glencoe scenery via the Ballachulish Bridge.

Elsewhere, the W2 circular from Stornoway calls at the 5,000-year-old Callanish Standing Stones and the Iron Age broch at Dun Carloway on Lewis; Stagecoach's 585 hugs the 'Ayrshire Riviera' from Ayr to Largs, with views of Arran and Ailsa and a stop at Nardini's Art Deco ice cream parlour; the 56 from Portree opens up Skye's quieter northwest, with otters, seals and even passing orcas near Milovaig; and First Bus's 1E links Glasgow to Balloch, gateway to Loch Lomond, in 32km.

The catch: rural timetables can be sparse and several routes don't run on Sundays, and each leg of a multi-bus trip needs its own £2 ticket. Still, for anyone put off by Skye's campervan congestion or the North Coast 500's parking headaches, the bus is easier on locals and on nerves — no blind bends, no kamikaze sheep, and the odd dram at journey's end.
