The Playa de la Concha is in the Bay of the Concha, flanked by the hills of Urgull and Igeldo. It is one of the hallmarks of this city. With an average length of 1,350 metres and a width of 40 metres, it has an approximate surface area of 54,000 m2. Its fine, golden sand is very shallow and the surging tides often limit the amount of beach area available to bathers, a drawback that is offset by the magnificent views. The beach is a prime destination to take in regattas during the day and at night, the fireworks during the Semana Grande (Great Week) celebrations.
