The road runs entirely over 1.900m above the sea level. It’s asphalted but very narrow, impassable for 2 cars at the same time. The road creates a shorcut between Col de Pailhères and Col des Trabesses.
The road is not plowed in winters. There’s a high risk of rock slides. The drive is pretty steep. It’s 550m long with an elevation gain of 72 meters. The average gradient is 13.09%.
