FREE rooftop views: If you don't have time or a desire to go up to the top of the Eiffel Tower or the Arc de Triomphe, head over to the Galeries Lafayette. This department store has a rooftop that is open to the public and is much less crowded than the other view points. You can get panoramic views of Paris for free! Just take the escalators all the way to the top. There is a pricey bar at the top as well.
