While attending the exhibition, take a chance and get to know Zurich and the country. Switzerland offers an amasing variety of landscapes, cultures and sights on quite small space, so travel is short. See the Alpes or Europe's largest waterfall just one hour away from Zurich and sunny Ticino or famous Matterhorn are just three hours down the road.
But don't miss Zurich, as "Donwtown Switzerland" offers many attractions for sightseeing and entertainment in itself. Find some links here that get you right into the action.
