My tip“Visits are by ticket from the nearby tourist office; combine it with the Eagle caves (Cuevas del Águila), 10 minutes away.”
A 15th-century castle built by the Constable Ruy López de Ávalos, and its name is linked to the widow of Álvaro de Luna, who took refuge there after her husband’s execution. It stands in a town south of Gredos with a mild climate and chestnut groves.
Easy to reach
Buses from Madrid; the castle is in the town, with a nearby car park and level ground. Full services.
