Lucerne is no stranger to mass tourism: The otherwise lovely medieval city swells each summer with list-checking visitors en route to central Switzerland’s famed Pilatus and Titlis mountains. Surprisingly, few of them make the 15-minute trek from the train station to this gorgeous 19th-century badi (open-air swimming area) on the Lucerne National Quay, overlooking the clear blue waters of what the locals call the Vierwaldstätter See (aka Lake Lucerne). The entire facility was meticulously restored in 2010 and remains a favorite of residents for its excellent views of brooding, multi-horned Mount Pilatus, Jean Nouvel’s lakeside KKL performance hall, and Santiago Calatrava’s Lucerne Station Hall—and all without the hassle of tourists.
