Friends! Suppose you were going to be in Paris for 8 days this June, with a spouse and a 14yo. What are some lesser known or not obvious things you would plan to do? Any recommendations? I mean besides the standard stuff like the Louvre, Catacombs, etc.

@mcnees the standard things will be overcrowded, most probably.
(certainly on weekends)

Chicago Institute of Art, actually, has such great collections that make it possible to skip Paris musea without too much to lose (and I did spend months in Paris in the past, so I can compare).
My personal choice of a museum would be Centre Pompidou.

Just walk around, sit in cafes, and look at buildings and people πŸ™‚. And don't forget parks, such a Jardin du Luxembourg, Jardin des Tuileries, and Bois de Boulogne.
