It is part of Norwegian County Road 63 that connects the town of Åndalsnes in Rauma and the village of Valldal in Norddal Municipality.

A normal operating season stretches from mid-May to October, but may sometimes be shorter or longer due to weather conditions.
Trollstigen (along with County Road 63) was officially opened as a national tourist route by the Minister of Transport and Communications on 16 June 2012.
