Much like La Concha Beach, Ondarreta Beach is backed by a promenade and can be reached from La Concha by walking through the Tunel de Antiguo. Only slight less busy than La Concha in summer, this beach is popular with sunbathers and volleyball-playing locals. A bike tour is a great way to get a look at the beach scene in addition to other San Sebastian attractions.
Ondarreta ends at the foot of Monte Igueldo, but if you continue along the promenade, you’ll reach a renowned piece of outdoor art by sculptor Eduardo Chillida entitled “Peine del Viento,” or “The Comb of the Wind.” Since 1977, these three pieces of curved steel, set into the rocks along the bay, have been pounded by wind and water.
