Yes, the first bar on our list is in Berlin, a city that is notably not on the seaside. But Berliners have made this little strip of the Spree River into a beach, complete with sand, beach chairs, an open-air bar, and a pool that actually floats in the river. In the winter it remains open as a “wellness retreat,” with the pool heated, and with two saunas. Oh, and they have table tennis. Well done, Berlin.
