Don’t come to Zurich and expect to stay dry. Flussbad Au-Höngg, (known as Werdinsel to locals), is one of dozens of swimming lidos called “badi” that pepper the city. It’s a 20-minute tram ride or 20 minute pleasant bike ride along the river's bike paths from the city center and is divided into two distinctly different sections: the lush manicured lawns and kiddie pools, which draw families, and the stretch of unkept meadow further north, home to an FKK crowd (a clothing optional counter culture wildly popular in the German speaking world) where you’ll encounter Mohawk-totting nudists to burkini-clad gay Goths and the occasional jaw agape tourist. The water at both is a beuatiful shade of green, but at the latter it's especially fast moving and jumping in it from the dirt paths along the riverbanks is not for the faint of heart. But your reward for doing so is a high-speed aquatic thrill ride down a tree-lined deep river stream of turquoise Alpine water. Wear goggles and stay underwater to heighten the “Aquaman effect” of flying underwater.
