Mount Urgull, the eastern exclamation point of La Concha, is now a lovely public park. This is the site of an old fortress (Castillo de Santa Cruz de la Mota), of which there are some interesting remnants to walk about. Several winding paths lead you past woody areas and monuments, and a few stray cats. There are plenty of multilingual signboards that provide historic capsule summaries of the relics such as a chapel, a cemetery, and ramparts with cannons. You can get some fine views of the Parte Vieja (old town) cityscape below, the beautiful string of beaches, the tiny Santa Clara Island, and finally Mount Igeldo. The summit of Mount Urgull is marked by a giant figure of Jesus Christ.
Take a pleasant walk along the Paseo Nuevo, which rings the base of Mount Urgull. This promenade is popular with the local joggers. There are plenty of interesting activities and buildings to be found along the way, including an aquarium and oceanographic museum, naval museum, and boats to Isla Santa Clara during the warmer months. Nearby are the City Hall (which was previously a casino), the Club Nautico yacht club, and the Museo de San Telmo, a collection of Basque works housed in the cloister of a 16th century monastery.
