Zurich, Switzerland
You may think of Zurich as a cold ski town, but we suggest visiting in the summer to see the city in all its glory. Zurich’s transformation from a busy, cold Germanic city to a carefree Italian one happens in early June, when, at once, the grays turn pastel and restaurants set tables out along the zigzagged streets. The best part: It’s not overrun with tourists like Venice, Barcelona, or its Swiss neighbor Lucerne, just 32 miles southwest. Make sure to spend some time at Sechseläutenplatz, a spacious, lakefront town square made with slabs of sparkling Vals quartzite.
