Switzerland may be a landlocked country in the middle of Europe, but with about 6% of Europe"s fresh water flowing through its countless rivers and lakes, there are plenty of outdoor swimming spots to cool down in the Swiss summer heat. Today, we"re dipping our toes in the pristine waters of Lake Zürich in Switzerland"s largest city, which has developed its own urban lido culture. Dotted across Zürich, you"ll find lots of lidos (public open-air swimming pools or bathing beaches) that make the most of the city"s lakes. This time of year, it"s common to see bankers and other workers change from business suits into bathing suits as they enjoy a quick swim during their lunch break.
