Cuitu Negru is a high mountain pass at an elevation of 1.858m (6,095ft) above the sea level, located in the municipality of Lena, in Asturias, Spain. The wild, remote and steep road to climb the summit was asphalted in 2012, to be a final stage of Vuelta a España race.
The first meters on this wild pass have slopes between 24% and 25% and the last 500m are higher than 17%. It’s so steep that the top 2.5 kilometres were only a goat track and have had a concrete surface laid just for the Vuelta.
Starting in Brañillín, a small town near the Valgrande-Pajares ski station, the steep dirt track to Cuitu Negro (or Cueto Negro) has a total length of 2.8km, with an average slop of 13,3%.
