A must see for Paris. If you want to go up, I recommend buying your tickets online well in advance of your trip. If you want to go up to the very top (3rd level) tickets can be hard to come by, as they limit the number of people up there. There is a lot of construction around the base of the tower, so be prepared to do some walking. A lot of street vendors are outside the tower selling souvenirs and wine/champagne. Lots of people picnic along the promenade - bring a blanket if you want!
