Trollstigen (English: The Troll Path) is a mountain road in Rauma, Norway, part of Norwegian National Road 63 connecting Åndalsnes in Rauma and Valldal in Norddal. It is a popular tourist attraction due to its steep incline of 9% and eleven hairpin bends up a steep mountain side. Trollstigen was opened on July 31, 1936, by King Haakon VII after 8 years of construction.
The road up is narrow with many sharp bends, and although it has been widened in recent years, vehicles over 12.4 metres long are prohibited from driving the road. At the top there is large parking place which allows visitors to leave their cars and walk for about ten minutes to a viewing balcony which overlooks the road with its bends and the Stigfossen waterfall. Stigfossen is a beautiful waterfall which falls 320 metres down the mountain side.
