Monte Dubasso is a high mountain pass at an elevation of 1.538m (5,045ft) above the sea level, located in the Italian region of Piedmont.
The road to the summit is extremely narrow. If two vehicles have to pass each other, one might have to reverse for some kilometers of winding narrow road to get to a place wide enough to pass. It shouldn’t be attempted by those who don't know how to reverse.
The road is paved with concrete at the beginning. At this part the road is called Strada Provinciale 216. But most of the road is gravel, impassable for a 2wd car. Very slippery when is wet.
