The tiny Isla de Santa Clara, right in the entrance to the bay, protects the city from Bay of Biscay storms, making La Concha one of the calmest beaches on Spain's entire northern coast. High promontories, Monte Urgull on the right and Monte Igueldo on the left, dominate the entrance to the bay. From June through September, ferries run from the mainland every 30 minutes, and are packed on summer weekends. There's a small bar at the ferry dock, and lifeguard service at
a beach that reveals itself only at low tide. Bring sandals, as the coastline is rocky.
