Mountain Road
Trollstigen
This twisting, sky-topping corkscrew of a road is the most famous stretch of tarmac in Norway. Completed in 1936 after eight years of labour, the Troll's Ladder is a stunning feat of road building, spiralling up the mountainside through 11 hairpin bends and a 1:12 gradient, and after heavy rain, waterfalls cascade down the mountainside, drenching cars as they pass. To add to the thrill, much of it is effectively single-lane, meaning traffic jams and passing vehicles are part of the hair-raising experience.
