Trollstigen (English: Trolls' Path) is a serpentine mountain road in Rauma Municipality, Møre og Romsdal county, Norway. It is part of Norwegian County Road 63 that connects the town of Åndalsnes in Rauma and the village of Valldal in Norddal Municipality. It is a popular tourist attraction due to its steep incline of 10% and eleven hairpin bends up a steep mountainside. During the top tourist season, about 2,500 vehicles pass daily. During the 2012 season, 161,421 vehicles traversed the route, compared to 155,230 vehicles during 2009. The road is narrow with many sharp bends, and although several curves were widened during 2005 to 2012, vehicles over 12.4 meters (41 ft) long are prohibited from driving the road. During the 2011 and 2012 seasons, buses up to 13.1 meters (43 ft) were temporarily allowed as a trial. At the 700-meter (2,300 ft) plateau there is a car park and several viewing balconies overlooking the bends and the Stigfossen waterfall. Stigfossen falls 320 meters (1,050 ft) down the mountainside. The pass has an elevation of approximately 850 meters (2,790 ft). Trollstigen is closed during late autumn and winter. A normal operating season stretches from mid-May to October, but may sometimes be shorter or longer due to weather conditions.
