La Concha

A city beach that keeps a storm up its sleeve, and arrives in 20 minutes.

The hang

La Concha is San Sebastián's city beach, 1,110 metres of it by our measurement, and for all that it feels surprisingly relaxed, one guide says. In season, lifeguards patrol and swimming zones are flagged; there are free toilets, showers and changing rooms, and umbrellas, tents and loungers rent for €15 a day. Two things to know: at high tide the sea takes back much of the sand, along with anything left too close, and a galerna, a sudden coastal storm, can form offshore and reach the beach in under 20 minutes.

The real intel

Best months · warmest sea: July and August (23.2 °C each), then September. Coolest: February (13.4 °C). One year of data, 2025.
Best months · emptiest: No crowd data by month. At low tide the beach looks enormous and everyone crowds into one section.
Getting there: Fly to Bilbao or San Sebastián, or take the high-speed train from any major Spanish city.
Cost reality: Umbrellas, tents and loungers €15 a day. Toilets, showers and changing rooms are free.
The catch nobody tells you: A galerna can blow in from offshore in under 20 minutes, and the high tide takes back most of the sand.

The crowd

Central, and still surprisingly relaxed.
