Super panoramic climb from Varenna to Passo Agueglio. Little traffic on weekends, just watch out for groups of motorcyclists who sometimes tend to cut corners too much. There is a bit of everything, hairpin bends, straight sections, significant slopes, especially at the beginning and end of the ascent, you pass by some villages and then through more wooded areas. Once you reach the top, a truly remarkable panorama opens up which, as they say, repays the effort. Watch out for the descent on the other side, the asphalt is in good condition and it's really fun to do but you often find rocks in the middle of the road.
