I will be traveling to Paris with my adult children and 3 kids (ages 11 and two 8 year olds). Looking for fun things to do with kids. Thanks in advance
Run over to Trip Advisor and they have a sidebar in the Paris forum that is about things to do with kids in Paris -- so a start..
If you are there in good weather the old fashion amusement park Jardin Acclimatation which is adjacent to the Louis Vutton Fondation museum is fun for younger kids. If you go to the museum (we have been to three exhibit there and each one has been outstanding) then admission into the gardens is free. You can buy ride tickets on machines throughout the park.
The Chateau Vincennes is in Paris on the edge of the Bois de Vincennes and it is a classic old fortress castle - the sort of thing little kids imagine when you say castle. I bought my then 7 year old grandson a model castle of cardboard there that was very high quality and fun to put together.
Again in good weather, you can rent model sailboats in the Luxembourg Gardens and the Tuilleries to sail on the fountain pools -- out kids enjoyed doing it.
Time of year is important. spring summer and fall, there are lots of outdoor things to do as well as nearby day trips to interesting places. In winter, I'd be thinking about museums and how to make that experience fun for the kids.
