The road from Høydalsmo to Dalen is spectuacular, the rest is also very good!
First part of Suleskarvegen ( www.suleskarvegen.no ). Quite scenic, especially going down the hairpins to Dalen (Tokke). Plenty of corners of all types and mostly decent surface though some less good sections.
Very nice route, with lots of great scenery
(mountain lakes, valley gorges, waterfalls, etc).
You can stop in Dalen and stay at the historical hotel,
built in a Dragon/Fairytale-style www.dalenhotel.no.
