A drive across Valdresflye is a truly unique experience, providing an endless vista of countless mountains and lakes. The road virtually floats across the plateau. Passing its highest point at 1389 metres above sea level, it grazes the edge of Jotunheimen National Park.http://www.valdresflye.no/main_uk.html
Fabulous mountain route, with many many great views. Check out the Besseggen ridge, if you have the time to hike it http://en.wikipedia.org/wiki/Besseggen
Along the route there are many good hotels and lodgings. If you prefer, you can stay in supercharming mountain-lodges, such as Brimi Fjellstugu. It is - surprisingly for those that have not heard of Arne, the cousin of the guy who runs it - also a gourmet destination not to be missed.
Two places along the route there are special stops with great photo-ops.
