Although I was in and around Paris for 3.5 days, we only spent one day walking around downtown Paris (the other 2 days were Disneyland and then a van out to Normandy). It was great fun to walk around to see many of the sights. We did not go up into the Eiffel Tower as the wait would have eaten up a good chunk of our day, but we did walk by.

We walked to the L'arc de Triomphe which you can walk up the 284 steps to get an amazing view of Paris (and without the 2 hours wait!). Here was the view down the Champs Elysees. Which way to go? by John Wolff, on Flickr
