The Troll Ladder is a mountain road in Rauma, Norway, part of Norwegian National Road 63 connecting Ã…ndalsnes 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 meters 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 meters down the mountain side.Trollstigen is closed during the fall and winter months. A normal opening season stretches from the mid of May to October, but may sometimes be shorter or longer due to changes in the weather conditions.
In the summer of 2005 the road was repaired and about 16 million NOK was spent on protection against rockfall, making the road a lot safer to drive on.
