Playa De La Concha, August 2015. Everybody and their dogs had told me about how great San Sebastián is. But sometimes the more a thing gets built up, the more mother reality tends to serve up a big old spoon of anticlimax. Thankfully that wasn’t the case with this stunning city. A major highlight of my trip across northern Spain, San Sebastián’s main stretch of sand, known as La Concha, is possibly the most impressive city beach I’ve ever seen. Even in the height of summer, with its teeming crowds and associated annoyances, there was no denying its magical atmosphere.
