Muro di Campeggio: Driving the 29% Gradients in Emilia-Romagna
Located in the Metropolitan City of Bologna, within the Emilia-Romagna region, Muro di Campeggio is a short but exceptionally steep paved climb. Positioned north of Pergoloso, this road is known in the cycling world as one of the most severe ascents in Italy, testing both vehicle traction and engine torque.

How steep is Muro di Campeggio?
The road is fully paved with asphalt, but its technical difficulty lies in its extreme incline. While the total length is less than two kilometers, it maintains a staggering average gradient of 15.9%. The most critical sections feature ramps in excess of 29%. To put this into perspective, this climb is mathematically more severe than the famous Muro di Sormano, which is often considered the benchmark for steepness in European road cycling.
Driving and Cycling Logistics
For motor vehicles, Muro di Campeggio requires a perfectly functioning cooling system and high levels of torque. On the 29% sections, weight distribution is key to maintaining tire grip, especially if the asphalt is damp or covered in autumn leaves. For cyclists, a specialized gear ratio (such as a 34x32 or higher) is mandatory to avoid stalling. The road is narrow and winds through a forested area, meaning visibility is limited on the steepest hairpins. Descending this road is equally hazardous, requiring constant modulation of the brakes to prevent glazing or failure due to extreme heat buildup.
Where does the Muro di Campeggio start?
The ascent begins in the valley near Pergoloso and climbs rapidly toward the ridge. It is a local road used mainly by residents and agricultural vehicles, so traffic is minimal but often unexpected. There are no safety barriers on the tightest bends. Given the severity of the 29% ramps, it is recommended to check tire pressure and brake pad wear before attempting either the climb or the descent. In winter, even a light dusting of frost makes the surface impassable for most standard vehicles due to the impossible traction requirements on such a steep grade.
