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.

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.
