The six-kilometre long Trollstigen Mountain Road is part of the RV63 which connects Romsdal with Valldal and Sunnmøre. The road is normally open from mid-May to sometime in October, depending on when the snow arrives and when it melts.
Drivers who drive this challenging road are rewarded with a viewing balcony at the top, offering spectacular views of the winding turns and the Stigfossen waterfall which also runs down the mountainside
Vehicles more than 12.4 metres long are not allowed on Trollstigen.
Trollstigen was opened on 31 July 1936 by King Haakon VII. The road took eight years to build.
