Rallarvegen

Located in Aurland county, this construction/access road was built from 1902 to 1904 for the railroad. The surface of the road is gravel, with steep sections and hairpin turns climbing up to 1.343m (4,406ft) above the sea level. It’s impassable from September to early/middle of July. The road is now a popular bicycle road offering both a historical and close-to-nature adventure. The road was hand-made and used as a transportation route during the building of the Bergenbanen railway from 1895-1902. 

This trail passes through remote areas, so you need to be prepared. This route is not suitable for normal cars. If you dare to take the risk and travel along this dusty and bumpy route, then make sure to be driven by someone who has experience of the road. You need a special permission to go by a vehicle on this "road", and you will need a vehicle that is very "capable". This so called "road" was never meant for vehicles, and can be a bit treacherous!
