Europe's highest cogwheel railway has been climbing through staggeringly beautiful scenery to Gornergrat (3089m) – a 30-minute journey – since 1898. On the way up, sit on the right-hand side of the train to gaze at the Matterhorn. In summer an extra train runs once a week at sunrise and sunset – the most spectacular trips of all.
Tickets allow you to get on and off en route; there are restaurants at Riffelalp (2211m) and Riffelberg (2582m).
At the top, you'll be greeted by arresting views of the Monte Rosa massif and Switzerland’s highest peak, Dufourspitze (4634m), with the second-largest glacier in the Alps snaking down from its summit. It rises above some 29 mountains towering above 4000m, including the mighty Matterhorn.
