A must do- but you might want to take the elevator to the top! We climbed (and climbed and climbed!) the narrow spiral staircase and it was an experience! In fact my sisters and I sat to rest a couple of times (we're in our 50s) and younger people had to step over us, lol! A great memory! The view from the top at night is phenomenal, the lights of cars up and down the Champs Elysses truly creates a moving spectacle of light. The Eiffel Tower sparkles in the distance and life is good in the City of Light.
