Glacier Express Zermatt to Davos Switzerland

Known as the train to fall in love on, the Glacier Express seven hour journey through the Alps to Davos crosses 291 bridges and goes through 91 tunnels, which means there s plenty of opportunity for a quick kiss in the Alpine darkness. With the Oberalp Pass, the Landwasser Viaduct and the UNESCO World Heritage Site of Abula being just some of the highlights, you re unlikely to tire of the scenery, either.
