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. During the top tourist season about 7,000 vehicles pass daily.

The road 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 falls 320 metres down the mountain side. The pass has an elevation of approximately 850 metres.
