The mythical road to the summit, also known as Guarramillas pass and Alto de las Guarramillas, is totally paved with rough cement.

Is the road to Bola del Mundo steep?

The fearsome road to the summit is brutally steep, hitting a 23% of maximum gradient through some of the ramps. The Bola Del Mundo was first included in the Vuelta a España in 2010. Starting at Puerto de Navacerrada, the ascent is 3.1km (1.92 miles) long. Over this distance the elevation gain is 361 meters. The average gradient is 11.64%. After 300 metres there is a first steep ramp of 16%, and another of about the same percentage after approximately one kilometre. The 23% segment, which is the hardest of all, comes just 500 metres before the summit. Alberto Contador, winner of all three grand tours, said ‘it’s a very difficult, dangerous climb. It’s incredibly steep and probably harder than Cuitu Negru. The climb is so hard, that despite living around there, I rarely go up it.”
