Le Café des Sciences sur Paris

An inexhaustible source of knowledge for young and old alike, in every field and in every conceivable form. You can easily spend several days there without monotony or boredom.

A fantastic place to spend the day with children. The new Children's City (for older kids) has been a huge success. All the exhibitions are high quality, not to mention the planetarium, which is superb! The only downside is the extremely poorly designed online ticketing system. When you buy a ticket for the Children's City plus the exhibitions, the process becomes incredibly complex, with time slots to select on different pages and no way to go back without canceling your order. Having to use a pen and paper to check that all the time slots work seems a bit odd in 2026.

A place full of discovery and fun! Book in advance (although you will still have to wait).

Great day out for the family. The space is fantastic and cool on a very hot day. The Submarine visit was fascinating. The planetarium movie was great fun. And we stayed until the last minute. Highly recommended!

Learn, learn, learn... Well, that's where you need to go!

We visited the Children's City (ages 2-6) and unfortunately, 1 hour 30 minutes is far too short to experience all the different areas. We didn't dawdle, but if you want to see everything, the allotted time is clearly insufficient, especially considering the 15-minute show. It's a shame! We had to rush our 4-year-old son and weren't able to finish the adventure at the Children's City.

Update: I had been waiting for the reopening & renovations and I’m not disappointed ! Absolutely wonderful ! One has to give credit where it’s due. ….. First off, I want to say that this place is worth taking the kids to—not because it's well-managed, but because kids will still have fun regardless. Our 3-year-old son had an absolute blast, and the little details that bug adults tend not to matter as much to children. That being said, there are definitely some areas for improvement: The facility is quite run-down, with visible signs of mold, decay, and years of neglect. It’s clear that very little funding has gone into renovations. The kids' show lasted about 15 minutes and lacked creativity. It was just a lady moving two dolls around on a table—disappointing and uninspired. There are some serious safety concerns. There are rods that children can play with in the construction play area, but they’re heavy and could easily cause head injuries. There are also no proper breaks on these rods . This kind of oversight is unacceptable in a space for young children. Fingerprint stains and general grime cover most of the glass surfaces. The "aquarium" looks like an asian sea food restaurant. The bathrooms are in poor condition—with broken or non-working hand dryers. The on-site café is well below average. It sells overpriced drinks and snacks with no added value or appeal. In the wet play area, the aprons provided didn’t fasten properly for any of the kids. The Velcro was worn out and just hung open. One of the main interactive displays was clearly broken and left running on an automated loop, falsely presented as interactive. It’s a real shame, because the original idea behind this was obviously visionary and brilliant for its time. But the current execution feels like it’s just being used as a cash grab, with minimal effort put into upkeep or service. Overall, quite disappointing—especially if you've visited similar science exhibits in other countries that are clean, engaging, and well-maintained

A nice and very educational place for young and old, unfortunately a major problem with the management of the planetarium…

A beautiful place for family discoveries.

Nice interactive museum. Some zones were closed for construction
