The Muro di Sormano, above Lake Como, built a reputation as the most brutal wall in Italian cycling during its brief run in the Giro di Lombardia in the 1960s, before being reborn as a cyclotourism benchmark.
A climb that ends in a wall
From Nesso, on the shores of Lake Como, the road climbs 13.5 km for 1,100 m of elevation gain up to the Colma di Sormano, through an already demanding but mostly rolling profile. The final kilometre and a half changes character entirely: this is the Muro itself, a gradient that exceeds 25% in places, lined with phrases painted on the road to encourage riders through the difficulty.
Getting the ride right
A wide-range cassette, around 32 to 34 teeth, is non-negotiable if you want any chance of clearing the final wall without putting a foot down. It pays to save as much as possible for that last kilometre and a half, since the earlier part of the climb is noticeably more manageable by comparison.
When to go
April to October, the road being rideable year-round but tourist traffic around Lake Como getting heavier in summer. Spring and early autumn offer calmer conditions for tackling the wall.
Good to know
Bellagio, a few kilometres away on the lakeshore, offers a wide choice of tourist accommodation, with convenient access to other Lario classics like the Madonna del Ghisallo for a cycling stay centred on Lake Como.
