Is it true that public transport in Geneva is free?+
Yes, if you're staying overnight in Geneva. Every guest at a hotel, hostel or campsite receives a Geneva Transport Card at check-in, valid on trams, buses, city trains and the Mouettes boats for the whole stay. On top of that, a machine in the airport arrivals hall issues every passenger a free 80-minute ticket, so even the trip from the airport into town costs nothing. Ask for the card at reception, since it isn't always handed over automatically.
Can you visit CERN and see the accelerator?+
The Science Gateway visitor centre is free, needs no booking, and houses the original Synchrocyclotron accelerator along with numerous exhibits; tram 18 gets you there from the centre in 20 minutes. Ordinary visitors can't enter the LHC tunnel itself, since it's live during operation and only accessible during technical shutdowns once every few years. Guided tours with a scientist are booked online around 3 weeks ahead and sell out within hours.
What do I need for a Palace of Nations tour?+
Book online a few days ahead, and above all bring a valid passport — an ID card isn't enough, and security won't let you in without one even if you've paid. The tour lasts around an hour, costs 22 francs, and runs in English or French. The chambers you see vary depending on which delegations are meeting that day. Ariana Park around the palace, with its peacocks, is open freely, no booking or passport required.
Is it worth a shopping trip to France?+
Yes, and half of Geneva does it. The border is 10–20 minutes by tram or train — Annemasse, Ferney-Voltaire, Saint-Julien — and groceries, restaurants and fuel are around 40% cheaper there. An ID card is enough for the trip. Watch the limits on the way back into Switzerland: purchases over 300 francs are meant to be declared, and meat and alcohol have their own quantity limits. On Saturdays, French supermarkets near the border are packed and the queues long.
How many days do I need for Geneva?+
For the city alone, 2 days is enough — the first for the old town, the cathedral and the lake, the second for the Palace of Nations and CERN. But Geneva is best used as a base for day trips: Chamonix beneath Mont Blanc is 1.5 hours by bus, Lausanne with the Lavaux vineyards 40 minutes by train, and Annecy 1.25 hours away. So 3–4 days is more sensible than 2. For comparison, Zurich alone offers more, while Geneva's strength lies in its surroundings.
When does the Jet d'Eau run, and is it always visible?+
It runs year-round from morning until around 11pm, and is lit up after dark from spring to autumn. It doesn't always run, though: it's switched off in strong wind, since it would spray the whole harbour, and in frost, when the pier would ice over. In winter it often keeps shorter hours. When it's on, you can walk out along the pier right up to the jet, but in a westerly wind you'll get soaked — bring a windbreaker.
Is French spoken in Geneva, or does English work?+
The official language is French, but Geneva is Switzerland's most international city, and English gets you by almost everywhere — in hotels, restaurants and shops. German, on the other hand, often doesn't, which surprises people. A little French goes a long way: saying "bonjour" on entering a shop is a social requirement here, and skipping it is considered rude.
When is accommodation cheapest?+
Counter-intuitively, in summer and at weekends. Geneva's hotels rely on conferences held by international organisations, so prices climb on weekdays in spring and autumn and drop in July and August, when the UN is on holiday, and at weekends year-round. The difference between a Tuesday in May and a Saturday in August can be double. If you're on holiday, aim for a summer weekend; if you must travel on a weekday, book well ahead or stay just across the border in France.
