If you have the opportunity to take the Bergenbanen train from Oslo to Bergen, we highly recommend it. This spectacular six-and-a-half-hour train journey takes you on a scenic tour of the Hardangervidda National Park.

This colourful and picturesque UNESCO World Heritage Site was founded in 1070 by King Olav the Third. Since then the area has been ravaged by fires and rebuilt on the same foundations, so the area is essentially unchanged since its founding. The Hanseatic League established an import and export office in Bryggen, which dominated trade for almost 400 years. Today, the area has several attractions, from the fish market to Bergenhus Fortress.
Fløien rises 320 metres above sea level and offers spectacular views of Bergen and the surrounding mountains. Riding the cable car up the mountain is one of Norway's most visited and popular attractions, and at the top you can enjoy Fløistuen shop and café, Skomakerstuen og Fløien folk restaurant. https://floyen.no/en
