Picón Blanco is a high mountain pass at an elevation of 1.512m (4,960ft) above the sea level, located in the province of Burgos, Castile and León, Spain. The summit hosts an abandoned military base.
Located in the Cantabrian Mountains, the road to the summit is paved (bad conditions due to the weather). The military base was built in the 1970’s and abandoned in 1999. Open to traffic throughout the year, the road may be closed for long periods in winter when the weather is bad.
The road to the summit is savage and hosted the arrival of the Vuelta a Burgos race. The savage pass is only mid-length, like many northern Spanish climbs, but entire kilometres average 11 and 12%. Starting from the village of Espinosa de los Monteros, the ascent is 8km long. Over this distance the elevation gain is 740 meters. The average gradient is 9.25%.
A minor narrow unpaved road west of the summit links the pass with Puerto de la Sía pass. The road is 4.8 km long. 4x4 vehicles only. It’s usually impassable in winters.
