La Concha

La Concha is the central beach of San Sebastián, in the Spanish Basque Country, a shell-shaped bay closed almost entirely by Santa Clara island at its mouth and by hills at either end.

That enclosure is the whole point. The Bay of Biscay is a rough sea and the Basque coast is a surf coast; La Concha is the one place along it where the geometry produces flat, sheltered water, and the city grew around that fact after Queen Isabel II began coming here for sea bathing in 1845. The promenade railing, a white wrought-iron design of 1910, has become the city's emblem and appears on more photographs than the beach.

The sand is fine and golden, the entry gradual, and the tidal range large enough that the beach roughly doubles at low water. The Cantabrian sea is cool — around twenty-two degrees in August — and swimming is straightforward. Zurriola, on the other side of the river, is the surf beach and is a different proposition entirely.

Development is a city front: the promenade, the belle époque quarter behind it, a funicular up Monte Igueldo at the western end and the Kursaal at the eastern. San Sebastián has among the highest concentrations of Michelin stars per head in the world, which is the other reason people come. Ondarreta at the western end is the quieter half of the same bay, and Zurriola across the Urumea is the surf beach with a completely different crowd.

An island across the bay mouth turns a rough coast into a swimming pool, which is why San Sebastián grew where it did. The tide roughly doubles the sand at low water. Zurriola across the river has the waves, the old town behind has more Michelin stars per head than almost anywhere, and neither is more than fifteen minutes on foot.
