Doing the Scottish Highlands by train is not only possible but is considered one of the most scenic rail journeys in the world. The two "crown jewels" of the Highland rail network are the West Highland Line (connecting Glasgow to Mallaig) and the Far North Line (connecting Inverness to Wick and Thurso). The West Highland Line famously crosses the Glenfinnan Viaduct, known globally as the "Harry Potter bridge," and offers views of Rannoch Moor that are inaccessible by car. In 2026, travelers can also take the Kyle Line from Inverness to Kyle of Lochalsh for incredible views of the Isle of Skye across the water. For a luxury experience, the Caledonian Sleeper allows you to wake up in the heart of the Highlands after departing London the night before. While the train won't take you to every remote glen or "Munro," the network covers the main hubs perfectly, allowing you to use towns like Fort William or Inverness as bases for further exploration via local buses or ferries.
