Monte Urgull is the wooded hill that closes the eastern end of the Concha bay, topped by the 16th-century La Mota Castle and the enormous statue of the Sacred Heart of Christ that watches over the city. The hill is criss-crossed by paths that rise steeply from the old town streets, and the walk to the top takes about 20 minutes from the Parte Vieja. The views from the summit are the classic panorama of San Sebastián: the perfect curve of La Concha below, the rooftops of the old town, Monte Igueldo in the distance, and the sea stretching out to the horizon.
La Mota Castle itself is partially open and contains a small military history museum, but the real reward is the walk and the view. The hillside is green and wooded even in summer, and the paths are busy with both locals and visitors. Start from the Plaza de Zuloaga, next to the San Telmo Museum, and follow the signs to the top.
