You can live like a medieval lord in this 10th-century bastion, home in the 16th century of Spain's founding emperor, Carlos V—hence it's alternative name: Parador El Emperador. Replete with suits of armor and other chivalric bric-a-brac, the place feels like a movie set (and has occasionally been used as one). Many rooms have views of the Bidasoa estuary. Reserve ahead and ask for one of the three "special" rooms, with canopy beds and baronial appointments, well worth the moderate extra expense.
