Europe's highest cogwheel railway has climbed through picture-postcard 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. Tickets allow you to get on and off en route; there are restaurants at Riffelalp (2211m) and Riffelberg (2582m). In summer an extra train runs once a week at sunrise and sunset – the most spectacular trips of all.
