• Stairs or elevators to the first two levels; the climb is about 600 steps, and only elevators go on to the top
• Glass floor on the first level, 57 meters up, where kids can look straight down at the people below
• Sparkling lights after dark, when 20,000 bulbs flash for five minutes on the hour, worth staying out for

The Eiffel Tower is the 330-meter iron tower on the Champ de Mars, with three levels open to visitors. The first level has a glass floor where kids can stand and look straight down to the ground.

Stairs climb about 600 steps to the second level, and elevators go all the way up. The top, at 276 meters, holds a champagne bar and Gustave Eiffel's old private apartment.
