Driving the vertical track to Rifugio Helios: A 2.328m climb in the Cottian Alps
Located in the heart of the Cottian Alps, in the Province of Cuneo, the ascent to Rifugio Helios is a brutal exercise in high-altitude logistics. Reaching an elevation of 2,328m (7,637ft) above sea level, this unpaved track—nominally part of the Strada Provinciale 251—is a relentless climb that rises high above the village of Maddalena. It is a road where the thin Alpine air and the verticality of the terrain demand total mechanical respect and a vehicle prepared for sustained high-torque operations.

How punishing are the 21 hairpins of the Rifugio Helios track?
The 5.2 km ascent from Maddalena is a high-stakes grind that packs 21 hairpins into a very short distance. With an average gradient of 12.44%, there is almost no flat ground to let your engine breathe. As seen on the exposed slopes of the Cottian Alps, the surface is entirely unpaved, consisting of fine dust and loose stones that offer poor traction on the steepest ramps. You need a high-clearance 4x4 with a reliable cooling system; ascending 647 vertical meters in such a short transit will push your temperatures to the limit. Each hairpin is a technical maneuver where the narrowness of the track leaves no room for error, especially if you encounter a local furgoneta or a tractor coming down.
What are the hazards of the SP251 alpine transit?
The road to Rifugio Helios is characterized by its extreme exposure and lack of safety infrastructure. The track is cut directly into the grassy mountainside, meaning that in wet weather, the dirt turns into a slick, muddy trap that can cause your wheels to spin out. The primary hazard is the "unprotected drop"; with no guardrails and a 12% slope, a single steering mistake or a mechanical failure like a snapped axle can lead to a terminal slide. From October to June, the road is buried under heavy snow, and even in summer, the winter's legacy is felt in the deep ruts and washed-out sections that litter the 21 hairpins. The isolation at 2,328m means you are entirely on your own if you suffer a puncture from the sharp Alpine rocks.
What is the best mechanical strategy for the descent back to Maddalena?
Coming down from the summit is a high-tension exercise for your brakes. A 12.4% descent over 5 km on a loose surface is the perfect recipe for brake fade. You must engage heavy engine braking and pick your line carefully through the most degraded parts of the track. Avoid the temptation to gain speed on the short "straights" between the 21 hairpins, as the dust makes it difficult to stop quickly before a tight turn. Scan the road far ahead for hikers and livestock, as the shoulders are soft and eroding. In this part of Piedmont, the road is a test of cooling integrity and brake control—stay slow, stay in gear, and respect the vertical scale of the Cuneo ridges.
