A very pleasant pass to climb up the Puebla de la Sierra side. To do this, you have to access it from Robledillo, with very steep ramps to warm up, and a few kilometers on a narrow and bumpy road. The views and the route are totally worth it. Avoid weekends, especially busy hours, as motorcycles, and especially cars, can spoil the party a bit, as I say, the road is very narrow. There is a fountain at the lowest point between Robledillo and Puebla, and another one when leaving Puebla de la Sierra. They are the only two points where you will be able to fill your bottles "for free".

It is an extraordinary and beautiful medieval Castilian town. But it has all its structures adapted to the modern age. Establishments and businesses abound everywhere. It is very well prepared for tourism.
