Paris With Kids: Parks and a Science Museum
Buying one ticket at Cité des Sciences and assuming it covers the children’s section too is the single most common planning mistake families make here, and it is an easy one to avoid once you know the two are sold separately.
Jardin d’Acclimatation: 42 rides in the Bois de Boulogne
This historic amusement and family park in the Bois de Boulogne runs 42 rides alongside a mini-farm and playgrounds, open 365 days a year: weekdays 11am to 6pm, and Wednesdays, weekends and school holidays 10am to 6 or 7pm depending on season. Garden entry alone runs about EUR7 adult, while the unlimited-rides Liberty Pass costs around EUR46; children under 80cm and disabled visitors enter free, per the park’s own site . Book a Jardin d’Acclimatation 1-day unlimited pass if the rides matter more than the garden alone, since the two price tiers are genuinely different products.
Cité des Sciences, and the separate ticket inside it
Europe’s largest science museum sits in Parc de la Villette, with standard exhibition entry running about EUR15 adult, EUR10 reduced, and EUR4 for ages 2 to 5. Cité des Enfants, the museum’s dedicated children’s section, is a separate ticket, not included with the main exhibition pass: full price around EUR13, reduced EUR10, ages 2 to 5 about EUR3.50, sold as timed 90-minute sessions that need booking ahead, per cite-sciences.fr . Book Cité des Sciences entry and check at checkout whether Cité des Enfants needs its own add-on for your dates, since assuming one ticket covers both is the trap here.
Building a day around both
Jardin d’Acclimatation and Cité des Sciences sit roughly across the Bois de Boulogne and Parc de la Villette from each other, on opposite sides of the city, so pick one per day rather than trying to combine them; both are full half-day-to-full-day destinations on their own.
What this category is not
Neither of these venues is Disneyland Paris, and neither needs the same multi-day-ticket planning; both work as a single, self-contained day. For the bigger theme-park version of a Paris family day, see the day trips guide rather than expecting either of these to scale up the same way.
Verdict: book Cité des Sciences and Cité des Enfants as two separate line items in the same checkout, not one, and confirm your session time for Cité des Enfants before you arrive, since its 90-minute slots do sell out on weekends. For the wider trip, start at the main Paris guide .
Check the specific weekday before you go. Jardin d’Acclimatation’s shorter weekday hours catch families out more often than its weekend and school-holiday hours, which run later.
