Head to Geneva, Switzerland's second most-visited city and one of Europe's greenest, for a unique sightseeing experience. Take a bus ride or hop on a mini-train, then explore the cobbled streets of Old Town with its Saint Peter’s cathedral, Place Bourg-de-four and various other historic landmarks. Don't forget to take pictures of the iconic Flower Clock – symbolizing the city's watchmaking tradition – and Jet d'Eau fountain! You will also gain insight into Geneva’s importance as a diplomatic and financial center while passing through areas around the UN building.
