Saint-Quentin-en-Yvelines
Go only for a reason: France Miniature with kids, the velodrome, or Chevreuse hiking. As a base for Paris it loses to staying in Paris.
Saint-Quentin-en-Yvelines (SQY) is a 1970s new town of eleven communes southwest of Paris, not a historic town. It holds France Miniature, a national velodrome and the gateway to the Haute Vallée de Chevreuse park, plus a large stock of late-20th-century architecture. Most visitors come for one of those, not for the place itself.

Get around
The town is spread over 11 communes and public transport is thin for its size. SQYBUS buses link the centres, €1.90 a single bought on board (cards often not accepted), and run infrequently at weekends. Walking between communes is cut by the N12, motorways and the railway. A car or bike makes the area far easier.

Etiquette, safety and scams
Etiquette
- Greeting: Say 'bonjour madame/monsieur' on entering any shop, bus or office; avoid: Asking a question before saying bonjour — it is read as rude
- Cheek kisses (la bise): Follow the other person's lead; one to four kisses depending on region; avoid: Initiating la bise with strangers or in business
- Addressing people: Use 'vous' and titles until invited otherwise; avoid: First names and 'tu' with older people or staff
- Restaurants: Wait to be seated in restaurants; call the waiter 'monsieur' or 'madame'; avoid: 'Garçon', snapping fingers, asking for the bill before you are finished
- Conversation: Debate is a pleasure; food, politics and philosophy are fair game; avoid: Asking about salary or religion; loud voices on trains
- Dinner at a home: Bring flowers (not chrysanthemums), chocolates or a good bottle; arrive 10–15 minutes late; avoid: Cutting the tip off a cheese wedge or asking for ketchup
- Dress: Smart-casual in cities; covered shoulders in churches; avoid: Beachwear in town centres
Scams and watch-outs
- Trappes has a reputation for crime and past riots; avoid the Merisiers estate, especially after dark.
- SQYBUS buses are infrequent on Sundays and public holidays; check the last bus before an evening out.
- France Miniature closes in winter and opening hours vary by day: check the official site before travelling.
- The N12 and motorway junctions are not pedestrian-friendly; do not plan to walk between communes.
The town centre is calm and middle-class; the main caution is Trappes, which has a history of crime and riots — avoid the Merisiers estate, especially at night. Elsewhere, normal big-city awareness is enough.
