The actual Palace of Versailles is a pain in the butt. You'll wait in line a while -- we waited an hour -- and once you get inside it's so crowded you can hardly see anything. The real treat is the gardens. Way in the back you'll find the Petit Trianon, and behind that you'll find the Queen's Hamlet, or Hameau de la Reine. My guidebook didn't even mention the Hamlet! It's like a little movie set of a rustic village from the late 1700s, featuring thatched cottages, a pond filled to the brim with fish, gardens full of flowers and vegetables, and a farm with cows, goats, sheep, donkeys, chickens and even rabbits. The Hamlet was far and away the biggest hit of our trip to Paris with the kids -- an absolute delight. They imagined the Queen romping around with her friends, pretending to be one of the "unwashed masses," which is exactly what happened here.

Open 9am to 6:30pm from April 1 to October 31. 9am to 5:30 from November 1 to March 31. Closed Monday and public holidays.
An awesome combination of superb palace and stunning gardens. Makes a great day trip from Paris which is 30 minutes away by train (and then a 10 minute walk from Versailles Rive Gauche train station to the palace). Tuesday and Sunday are the busiest days – and the website has a updated chart on what days will be busy and quiet. Gardens are stroller friendly but strollers can’t go into the palace rooms. Be prepared for lots of walking. Bike rentals available from both near the train station and inside the palace complex. Row boat rental at the garden’s Grand Canal. 

Parc de la Villette

Nestled in the far north of Paris is an under-appreciated park that is at the center of the Cité des Sciences et de L'Industrie, an ultramodern complex that itself encompasses a cultural center, a concert hall, a museum, and much more. The Parc de la Villette is a great place for kids and adults to explore and offers equal parts fun, beauty, and opportunities for learning. The Parc de la Villette's multi-themed gardens, open "prairies", and cultural center, and open-air cinema area are guaranteed to provide you with a memorable day in one of the city's less-explored areas.

• The Parc de la Villette have 10 thematic and original gardens that will easily amuse both adults and kids, including:
• Bamboo garden
• Dragon garden
• Fog garden
• Mirror garden
• Wind garden
• Dunes garden

La Villette (15)

This modern park and museum complex reinvigorated the former abattoir district with its red follies and themed gardens. On the northern edge, the Cité des Sciences (advance booking recommended, especially during the school holidays) swarms with kids, for its interactive exhibits in the Explora display, its excellent children's section and spherical Géode IMAX cinema. South of the canal are the Cité de la Musique music museum and concert hall, Zénith rock venue and Grande Halle, last remnant of the livestock market. Numerous events include circus, theatre, a summer outdoor film festival and Jazz à la Villette in September. The park is free but there are the following charges for the museums - Cité des Sciences: Explora, €8; 6-24 years, students, over 60s, €6; children under 6, free; Cité des Enfants, children 2-12, €8. Cité de la Musique museum: €7; under 26, free

2 km Chapelle'st

http://www.davidlebovitz.com/2009/04/ten-great-things-to-do-with-kids/
This is a reclaimed industrial landscape turned into futuristic park. Most of the playful park structures were designed by Bernard Tschumi with a child’s imagination in mind. 

La Chapelle

http://goparis.about.com/od/parisneighborhoods/a/lachapelle-guide-paris.htm

The La Chapelle neighborhood owes much of its current cultural landscape to the 1980s, when large numbers of ethnic Tamils fled the violent civil wars in Sri Lanka and landed in France.
