Very manageable route without major climbs.
Duration: a leisurely 3 and a half hours.
Before reaching Ubeire, around kilometer 30 of the route, we will find the Fuente del Rosal spring where we can refill water.
Duration: 7-8 hours (with stops)
Although Google Earth shows Polarda, I can assure you that this peak is El Buitre.
In winter, there may be snow since much of the route, if not almost the entire route, is above 1000 meters.
