The Aursjovegen Road, built in the 50's to help develop a series of dams for Hydro Electricity Generation.
It's basically and old trade route for horse and cart and 80% gravel.
Unfortunately we drove this at the end of the day as an alternative route home. Not realising it was about 50Km @ 20mph. Will definitely do this again and spend the day there visiting the various sites en'route.
Sit back enjoy the views and music......
