Fodor's Expert Review Flåmsbana

Although this trip covers only 20 km (12 miles), the one-way journey takes nearly an hour to travel through 20 tunnels and 2,850 feet up the steep mountain gorge. The masterpiece of Norwegian engineering took 20 years to complete, and today it's one of Norway's prime tourist attractions, drawing more than 1 million travelers each year. The train runs year-round, with 8- to 10 round-trips from mid-April through mid-October and four round-trips the rest of the year. Most tourists take the train round-trip, returning on the same train a few minutes after arriving in Myrdal.
