Great training climb, not too steep but not really flat either. Also a great view of the Inn Valley and the Alps - especially the Zamen Kaiser. Even after 30 years in the region, you can still look around here and enjoy the view of the Tyrolean Lower Inn Valley.
Small addition: Chris Jörg is right. The route is sometimes very hectic. Back then I drove the route on the Austrian national holiday - October 26th - in a fantastic hair dryer situation. It was, of course, pretty quiet in terms of car traffic. The variant via Rettenschöss is also great (only a little more demanding because it is steeper).
