Frequently Asked Questions About Visiting France
Entry requirements depend on your passport. Check your specific requirements on the France page at Yoogo.
France uses the euro (EUR). Credit and debit cards, including contactless payments, are accepted almost everywhere, though carrying a small amount of cash is useful for markets, small cafes, and rural areas.
France is generally safe, though pickpocketing is common in tourist hotspots such as the Paris Metro, around the Eiffel Tower, and on crowded trains. Keep valuables secure, stay alert in busy areas, and be aware of occasional strikes or demonstrations that can affect transport.
France has an excellent rail network, with TGV high-speed trains linking major cities in hours. Paris has a comprehensive metro and RER system, while regional trains, buses, and rental cars make exploring the countryside, wine regions, and coast straightforward.
Late spring (April–June) and early autumn (September–October) offer pleasant weather, fewer crowds, and lower prices. July and August bring warm Mediterranean weather but also peak tourism, while winter is ideal for Alpine skiing and Christmas markets in Alsace.
French is the official language. English is widely understood in Paris and major tourist destinations, though less so in rural areas, and making an effort to greet people with a polite 'bonjour' is genuinely appreciated.
No special vaccinations are required for most travellers, though routine immunisations should be current. Tap water is safe to drink throughout the country, and healthcare is of a high standard, though travel insurance is recommended for visitors.
A service charge (service compris) is included by law in restaurant bills, so tipping is not obligatory. Rounding up the bill or leaving a few euros for good service is appreciated but never expected.
France has strong 4G and 5G coverage, and EU roaming rules mean many European SIMs work without extra charges. Travel eSIMs and local prepaid SIMs are widely available, and free Wi-Fi is common in cafes, hotels, and public spaces.
Always greet shopkeepers and servers with 'bonjour' on entering and 'au revoir' on leaving, as it is considered basic politeness. Meals are unhurried, dress tends to be smart-casual in cities, and speaking quietly in public is the norm.
