Very challenging. The first thing to do is to set off early before the wind picks up. Pack your jacket, because it's still chilly in the mountains early in the morning, especially on the descents. From Garda it starts straight away over 10% and stretches for about 10 km. The last descent you can get more than 80 km on it. Only the last section with more than 10% is a very bad surface. Extreme caution there. Despite everything, you will be rewarded with a breathtaking view.
