It's a classic climb in the Vuelta a España and in cyclotourism events like the Perico Delgado ride. The switchbacks section is very demanding: The first 4 km are gentle (2-3%). From the Puente de la Cantina (Cantina Bridge), ramps of 6-7% begin. Between km 6 and 8 are the five tightest bends, almost linked together, in a wooded area. The final kilometer has a steep ramp before reaching the summit.

There's a fountain as you reach the top on the right. Follow the cobblestone path.
