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.

No water comes out, mind you. Even so, it's a legendary spot in the Navacerrada Pass.

Mandatory stop on the way down to refill water. (Or uphill, but you have little left and you have to suffer until the end)

One of the most beautiful and toughest passes in the mountains. Beautiful climb but little shoulder and a lot of traffic on weekends. There are a lot of bikes so it is not a problem because it is respected, but it is good to know. Be patient, and enjoy the wind, that stretch is tough but the reward is closer.
