This was the approach to Castrojeriz today. The town is in the valley, with the castle on the hill. Or from the other perspective:
Had fun exploring the castle ruins, much of which are 14th-15th century, with much older roots (possibly Roman.)
As the pictures show, finally some beautiful weather after two weeks of yuck! 20 km went pretty easily, lots of interesting conversations.
Tomorrow: Juntos Albergue in Boadilla del Camino.
