A 20km-long engineering wonder hauls itself up 864m of altitude gain through 20 tunnels. At a gradient of 1:18, it's the world's steepest railway that runs without cable or rack wheels. It takes a full 45 minutes to climb to Myrdal on the bleak, treeless Hardangervidda plateau, past thundering waterfalls (there's a photo stop at awesome Kjosfossen). The railway runs year-round, with up to 10 departures daily in summer.
