This traditional summer event has been animating Geneva for nearly a century. The city lays on a programme of free concerts on four open-air stages, plus a funfair, craft market and a huge number of internationally-flavoured food stalls lining the lakeside.
Parades and races, beach rugby matches and a Miss Geneva contest have all added to the amusement in past years, plus there's a Slow Up on July 31 and fireworks to celebrate Swiss national day on August 1. In all, around two million visitors are expected to turn up over the course of the month.
The whole shebang comes to an end – literally with a bang – on the final Saturday night of August 14, with probably one of the biggest and longest fireworks displays in the world.
