Hi Grannynise. How wonderful that you are taking your 11 year old granddaughter to Paris. I used to live there and for decades afterwords took students on study trips there. I suggest the following to do with an 11year old:
-Tour Eiffel + rides on the beajtiful caroussel( merry-go-round) opposite it. Buy multiple tickets as she will want to go round and round
- Bateaux Mouches( pick up onquai opposite Eiffel Tower( or Bateaux Parisiens, pickup under the "Pont neuf" which is actually the oldest bridge in Paris, despite the name. Worth doing this twice: once inthe morning and in the early evening, another time. It is magical to see the lights of Paris go on from your river vantage point.
--Notre Dame + climb up to the top for a spectacular human view of the city, a view of the famous bell, and she might know ghe qtory of the hunchback, otherwise, you can tell her
--La Sainte Chapelle , just a five minute walk from Notre Dame( within the grounds of the Supreme Court), fabulous ( and small) jewel of a chapelle: you will both be enchanted by the stained glass windows
--Centre Pompidou: musuem of modern art with much to interest a child, not least of all the structure itself, the escalator that gives a fabulous free view of Paris and the artists, jugglers, street performers outside
--I'd skip the Louvre( too big for first visit and tortuous and crowded to wade through to see only highlights, BUT take her to see the pyramid in the courtyard and have a chat about the juxtaposition of this in such a classical surrounding( free here). AND DO CROSS "Le Pont des B eaux Arts" in front of the Louvre and watch the artists drawing on the pavement
--Musee D'Orsay: great but will be crowded. Head for the ground floor only for the highlights, if you go.
--MUSEE RODIN- wonderful visit of Rodin's sculptures and gardens. The Thinker is in the garden and would provoke a great discussion with an 11year old. OPPOSITE is The Invalides with its golden dome. You can tell her about Napoleon, who is buried there
--JARDIN DE LUXEMBOURG: forget Eurodisney, go here for fun and real Parisian atmosphere. There is a wonderful lake where children sail model boats AND a terrofic activities playground which costs about 6 euros per person to enter( they stamp your hand) and she will have a great time on all the marvellous equipment, then you can lunch or have a snack in the outdoor café
--I would also tell an 11 year old about the Latin Quarter and walk around it, drinking inthe atmosphere and student life
--FINISH up with a visit to MONTMARTRE, which is in the 18th arrpndissement in Northern Paris: fun and full of stories to delight her, as well as fabulous views( beware of pickpockets
--ALSO, take her for a great ice-cream CHEZ BERTHILLON on the ILE ST LOUIS and let her see Paris from this tiny island on the Seine, behind Notre Dame
PM me if you would like more info. I could go on forever.
Have fun, both of you!
