Kristinm, you've also got the Bois de Boulogne nearby. We spent part of an afternoon rowing a boat around the Lac Inferieur and it was a blast. There's a rental fee and you need to leave a fifty euro deposit, it was great. The Foundation Louis Vuitton is there, too-it had not yet opened when we were there, but it's a stunning building to see, even if you don't go in. There is a Velib location too, in case you want to ride a bike through the area.
Also close by is the quirky Museum of Counterfeits, which I recommend. Examples there of real and fake Chanel, clothing, car parts, champagne, etc, quite interesting.
Here's a gallery from our day in the area:
