This is a very impressive 30km stretch of road, that takes in Silvretta Hochalpenstrasse toll road, a run directly through a preserved national park. The run up from the East can be briefly interrupted by a diversion just outside of Galtur up to Kops Stausee, a short twisty and steep ascent, but actually with good views since the valley is pretty muct pastures at this point.
The artificial lake Kaps at the top is quite interesting to run around, and stop and admire the views from. Return to Silvretta Hochalpenstrasse and about 1km later you pass through the toll booth (11 Euros) and start the ascent to the top. From this side the ascent is not so steep, you go straight into wide open valley sweepers, on the most beautiful road surface you can imagine, driving all the way to the summit of this road (Biehole Hohe) at 2036m, and the small lake directly adjacent to the road. It's worth stopping here to admire the views again, before starting the ascent down.
The ascent is also fantastic, initially very long sweeping bends, with nice granite rock faces either side, with great views ahead can be taken at speed, though do watch out for occassional coaches which can be popular during the peak summer season. As you ascend further, the roads become more twisty, with plenty of scattered switchbacks, but never overly aggressive - always a good surface, fantastic cambers (as only the Austrians seem do build to perfection). There are also plenty of nice waterfalls along the valley to admire. The final run to the bottom levels out through a small forest section, before you exit the national park. Unbeleivable drive, sights and sounds, and a complete snip for 15 Euros!
