How steep is the Muro di Campeggio road in Italy?
Muro di Campeggio is an exceptionally steep paved road located in the Metropolitan City of Bologna, within the Emilia-Romagna region of Italy. Positioned north of Pergoloso, this short stretch of asphalt is legendary in the cycling world, but for drivers, it represents one of the most mechanically demanding climbs in the country. It is a vertical wall of tarmac where the extreme incline pushes engine torque and tire traction to their absolute limits on every meter of the ascent.

What makes the Muro di Campeggio incline so dangerous?
The technical difficulty of the Muro di Campeggio lies in its sustained steepness. While the climb is just under two kilometers long, it maintains a staggering average gradient of 15.9%, with specific ramps hitting an incredible 29%. To understand the scale of this climb, it is even steeper than the legendary Muro di Sormano. At 29%, the road feels less like a path and more like a staircase; if you are forced to stop on these ramps, restarting the vehicle without burning out the clutch or spinning the tires into the asphalt is nearly impossible.
Can a standard car drive up Muro di Campeggio?
A standard car can theoretically make the climb, but only if the mechanical components are in perfect condition. The 29% sections put an immense strain on the engine's cooling system and require massive amounts of torque. If the asphalt is even slightly damp or covered in autumn leaves, 2WD vehicles will struggle to find enough grip to keep moving forward. The road is narrow and winds through thick forest, meaning there is no room to maneuver if your tires start to slip. High-performance brake pads are also essential, as the descent back down to the valley will cause heat buildup in seconds on such a vertical drop.
Where does the climb to Muro di Campeggio start?
The ascent begins in the valley floor near the village of Pergoloso and climbs rapidly toward the mountain ridge. It is a local road primarily used by residents and small agricultural vehicles, meaning that while traffic is light, it is often unexpected. There are no safety barriers or guardrails on the tightest hairpins, where the drop-offs into the woods are steep. Before attempting the drive, you must check your tire pressure and verify your brake fluid levels; any mechanical failure on a 29% grade leaves you with almost zero stopping distance before the vehicle begins to roll backward.
Is Muro di Campeggio passable in winter?
During the winter months, Muro di Campeggio becomes virtually impassable for motorized travel. Even a light dusting of frost or a thin layer of ice makes the 29% ramps a lethal slide. Traction requirements at this angle are so extreme that even winter tires may fail to provide enough "bite" to overcome gravity. The forest canopy keeps the road in deep shadow, meaning ice can linger on the steepest bends long after the sun has come out. Unless you are driving a vehicle with professional-grade winter equipment and a specialized 4x4 system, the Muro should be avoided at all costs during the colder months.
