Passport to the Big Bang

The Passport to the Big Bang trail lets you discover CERN's installations and learn all about its experiments. The Passport, a booklet full of questions for you to answer, directs you through information panels, offering a fun way to take in their content. You can visit ten information platforms altogether. CERN encourages you to use environmentally friendly modes of transport to get to the platforms, which can all be reached by cycle paths. The Passport is available free of charge from tourist offices and town halls in the Pays de Gex and the Canton of Geneva, from the Genève Roule (Montbrillant and Terrassière) and Meyrin Roule sites, from Pro Vélo Genève and from the CERN Reception. You can also download it from the dedicated website, or download our mobile app containing all the maps.
