Driving to Colle Pian Fum: A technical climb to the Cappella di San Michele
Located in the heart of the Graian Alps, in the Province of Turin, the climb to Colle Pian Fum is a high-altitude journey that perfectly captures the raw nature of the Piedmont region. Reaching an elevation of 1,999m (6,558ft) above sea level, this narrow route leads to the isolated Cappella di San Michele. It is a drive where the transition from civilization to the high mountains is marked by a dramatic shift in road quality, demanding absolute focus on the pedals and the steering wheel.

Does the asphalt hold up on the way to Colle Pian Fum?
The 7.3 km climb from Tornetti starts as a standard mountain road, but as you gain altitude, the surface integrity disappears. As seen in recent surveys, the asphalt becomes heavily degraded, riddled with deep holes and patches of gravel that can easily snag the undercarriage of a low car. The road is narrow, often barely leaving enough room for a single vehicle, and features 20 tight hairpin turns. With a vertical gain of 600 meters and an 8.21% average gradient, your engine will be under constant load, struggling for airflow as the track turns into a technical puzzle of avoiding ruts while maintaining enough momentum to clear the steep ramps.
What are the primary hazards near the Cappella di San Michele?
Near the summit, the environment of Colle Pian Fum becomes significantly more aggressive. The road surface transitions into a mix of broken pavement and loose scree, making traction a real issue on the 8% slopes. There are zero safety barriers, and the unprotected drops into the Turin valleys offer no margin for error. Sudden mountain fogs are common, turning the 20 hairpins into a blind navigation exercise. This is a "low-gear only" road where the lack of maintenance means you might encounter fallen rocks or washouts that force you to reverse back to a wider pocket—a maneuver that is high-stakes on such narrow, crumbling shoulders.
How to safely manage the 20 hairpins on the Piedmont descent?
Coming down from 1,999m is a brutal test for your braking system. Because the road is full of holes, you cannot maintain a fast rhythm; you are forced to use the brakes constantly while dodging the degraded sections. To prevent brake fade, you must rely on heavy engine braking and keep the vehicle in its lowest gears. Scan the road far ahead for oncoming local furgonetes, as passing them on the narrowest meanders is nearly impossible. In this part of Piedmont, the road is a test of patience and vehicle preservation—respect the broken surface, watch your clearance, and don't let the panoramic views distract you from the technical traps under your tires.
