Start your tour at the Basilica de Santa Maria del Coro in the Parte Vieja, the old town of San Sebastian, a baroque church completed in 1774 with a facade that includes depictions of the city’s patron saint and maritime symbols.
From this location, proceed through the narrow streets of the Parte Vieja to the Iglesia de San Vicente, the oldest church in the city dating to the 16th century with a Gothic structure and a carved retablo from 1584.
Continue to the Plaza de la Constitucion, a neoclassical square rebuilt after the fire of 1813 that once served as a bullring and features numbered balconies on its surrounding buildings.
Move next along Calle 31 de Agosto, one of the oldest surviving streets in the old town that escaped the 1813 destruction and leads towards the port area.
Head to the port and the Alderdi Eder park beside the Ayuntamiento, the city hall housed in a former casino building from the early 20th century, where the park includes gardens and a carousel near the start of the seaside promenade.
From the park, join the Paseo de la Concha, the promenade that follows the curve of La Concha beach for about 1.3 kilometres along the bay with views across the water to Monte Igueldo.
Walk the full length of the promenade past the railings and belle epoque architecture to the area near Ondarreta beach at the western end.
The route covers the historic core of the old town and the iconic bay promenade in a distance of roughly two kilometres and takes around one hour at a leisurely pace.
End at the Peine del Viento sculptures by Eduardo Chillida, three steel pieces installed in 1977 on rocks at the far end of the bay where waves crash against the shore.
