1. Oslo to Bergen, Norway
Connecting Oslo and Bergen is the fairytale Bergen Line. Take it in spring or autumn, and the voyage plays out like a living painting of all four seasons, as blustery flower meadows and lush valleys fade into icy forests of pine and glittering lakes. It’s a journey that’s quite possibly up there with the best in the world. It makes little difference which way you travel – views are equally OTT in both directions, on both sides of the tracks – but start in the morning to ensure you get a full day of views on the seven-hour trip. Ticket prices are generally quite affordable, but onboard food will set you back, so pack snacks.
