The road to the summit is brutally steep. It’s called CA-412. It’s paved but narrow. The climb is short and horrible at only 6km in length, but averaging almost 10%. There's a real sting in the tail too as the final 2km average 11.5% and includes slopes of up to 19%. It has been featured in Spanish Vuelta race. Notable winners here include Chris Froome and Joaquim Rodríguez - suggesting that despite its short length, it is certainly an ascent for proper climbers. It’s one of Chris Froome's favourite climbs.
