Susten Pass, Switzerland

For pure driving, this is one of the best. Great road surface, good width and endless sweeping curves as the scenery gets more and more impressive.

The initial stretch sweeps its way slowly up a beautiful scenic valley floor, road then steepens and starts to hugs the granite walls of the valley as it slowly climbs, with a series of beautiful sweepers, with great views to the road ahead, before a final tighter stretch with some nice switchbacks to the top. On the way back down make sure you stop for views of the Stein Glacier, there are a couple of decent parking areas on the way down (around 600M from the top of the pass), and its well worth stopping as you can get a great picture of your car with the glacier as a dramatic backdrop.
