2 Best Sights in San Sebastian, The Basque Country, Navarra, and La Rioja

San Sebastián's crown jewel is this sandy stretch that curls around the uninhabited Isla Santa Clara. One of the most famous urban beaches in the world, La Concha is filled day and night, rain or shine, with locals and tourists who go to swim, jog, stroll, and admire sand sculptures. The beach has clean, pale sand and few rocks or seaweed—but scant shade, near the promenade wall. Lounge chairs are available for rent. The calm surf makes it a favorite pick for families. Amenities: lifeguards; showers; toilets. Best for: sunrise; sunset; walking.

Across the Urumea River from La Concha lies this sprawling, less touristy beach. Exposed to the open Atlantic, the beach boasts waves that are often big enough to surf—and occasionally too dangerous for kids and inexperienced swimmers. Amenities: lifeguards; water sports. Best for: surfing.
