To prepare yourself for your rail journey, browse this little museum right beside the train platform. It's not just about railways; there are fascinating photos of construction gangs and life in and around Flåm before the car era.
This 20km-long engin-eering 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).
You can watch wild salmon and sea trout through viewing windows, see an excellent 20- minute film about the salmon's lifecycle, browse the interpretive panels, try to tie flies to increase the odds of you hooking one of your own and do a little virtual casting.
Some 30km southeast of Lærdalsøyri along the E16, this 12th-century stave church was raised beside one of the major trade routes between eastern and western Norway. Dedicated to St Andrew, it’s one of the best-known, most-photographed – and certainly the best-preserved – of Norway’s stave churches.
On the southern outskirts of the village of Vik is the splendid Hopperstad stave church , about 1km from the centre. Built in 1130 and Norway’s second oldest, it escaped demolition by a whisker in the late 19th century. Inside, the original canopy paintings of the elaborately carved baldequin have preserved their freshness of colour.
