Often referred to as the most beautiful train journey in the world, Norway's Flåm Railway is also the steepest. An impressive 12.5 miles, the journey takes you through fantastic nature, steep mountains, waterfalls, and tunnels before arriving at Myrdal mountain station; an impressive 867 meters above sea level. While the trip itself takes only an hour, you would normally first need to get to Norway, and now you don't even have to. Thanks to this virtual reality video by Expedia, you can experience it all from home, wherever that may be.
