One of the most scenic train routes in Europe zooms high into the mountains between the towns of Myrdal and Flåm. After the day-trippers have departed, it's a wonderful place to extend your tour and spend the night.
If you have time to kill before the train departs, make sure you visit the Flåm Railway Museum. Building the Flåm Railway was a remarkable feat in engineering, and this museum illustrates the challenges the builders faced in detail. You'll find it in the old station building, 300 feet from the present one.
This trip is only 20 km (12 mi) long, but it takes 40 to 55 minutes (one-way) to travel the 2,850 feet up the steep mountain gorge. The line includes 20 tunnels and a bridge. A masterpiece of Norwegian engineering, it took 20 years to complete, and is today one of Norway's prime tourist attractions, with more than 600,000 visiting each year.
