When in Paris, one can't help but notice the Eiffel Tower sooner or later. Designed by Gustave Eiffel, and built in 1889 just in time for the opening of the World Fair, the Eiffel Tower is one of the world's most recognizable structures. It has become not only a symbol of Paris but also an icon for the entire French nation.
So then, a visit to the Eiffel Tower should be the staple on every Paris tourist list of things to do. Depending on your physical constitution, you may either ride the elevator or climb the more than 300 steps each to the first and second levels. Restaurants are located on each of these levels which are a tad pricey but provide a great view over the city.
The third level, at the top of the tower, can only be reached by elevator. To access the Eiffel Tower, tickets must be purchased, and lines may be long. Regardless, if you've never been here before you will not want to miss this.
