From Oslo to Bergen, I took the Bergensbanen, which snakes through the icy peaks and serene lakes of Hardangervidda. The Flåmsbana branch ride dropped dramatically into waterfalls and steep valleys by the Aurlandsfjord, offering breathtaking views at every station. With temperatures averaging around 11°C in Norway this June, it's the perfect time to embrace the cooler climate while exploring these unforgettable landscapes.
