The Cité des Enfants, Paris' renowned museum for kids, is a haven of fun and education for children aged two and up. With its interactive exhibits, special-effects cinema La Géode, planetarium, and retired submarine, there is something for everyone. A range of combination tickets are available for booking online, but advance reservations are strongly advised for weekend and school-holiday visits, as well as for the year-round Cité des Enfants educational play sessions (1½ hours, for ages two to seven years and five to 12 years). Bring a picnic, bring the family and have a great day out!
