Surf all summer long in San Sebastián

Swim in the bracing British sea in Cromer

Enjoy urban floating in Bern, Switzerland
There's an art to joining Bern's thriving urban swim scene. Do as the Bernese do and think less 'swim' and more 'float'.

En route from London, you can stop in Basel to peruse art galleries and wander the Rhine river before continuing by train to Bern.
