The town is located in an elongated shell-shaped beach bay, nestled between two hills. The bay is protected by the small island de Santa Clara.
The summer residence, which was once very popular with the Spanish royal court as well as with the aristocracy and the upper middle classes and which, by the way, is called Donostia by the Basques, still shines with elegant promenades and noble mansions.
One searches almost in vain for truly historic buildings, because devastating fires have repeatedly ravaged the old town. Nevertheless, the old town center below Monte Igueldo is bursting with vitality. Clusters of people gather in front of the entrances to the Pitxo bars, which is only understandable in view of the delicious little delicacies piled up on the counters.
