About Geneva
City overview
Geneva is a compact Lake Geneva city where an old Calvinist hill town, lakeside promenades, watchmaking museums, and UN institutions fit between the Rhône outflow, Mont Blanc views, and the French border. The Old Town and Rues-Basses make the historic core, Pâquis and Eaux-Vives frame the lakefront, and Nations explains the diplomatic city beyond the postcard Jet d’Eau.
Food & drink
Geneva food is lake, cheese, and market-oriented: fondue and raclette cover melted cheese, longeole is the local pork sausage, filets de perche are small lake perch fillets, and roesti turns grated potato into a crisp pan cake. Bains des Pâquis, Plainpalais market, Carouge cafes, old-town chocolatiers, and summer quays add chocolate, picnics, and wine-facing brasserie meals.
