According to the Notre-Dame de Paris web site, there were 387 steps (!) to the top of the Tower. And no, there wasn't an elevator. John and I climbed and climbed. I thought I was gonna pass out! But the view was phenomenal and the effort was totally worth it.
We stayed in line for a couple hours in the cold before entering the base of The Tower of the Notre-Dame de Paris. We actually visited The Tower a couple days after visiting the cathedral because we wanted to start early in the day!
There were cool things and people to see while we stayed in line:
Looking up at the gargoyles (as "water spouts.")
A postal car parked across street.
A kid chasing pigeons.
A gentleman with a fresh baguette.
A girl rollerblading with her dog.
Looking down at the feet that belonged to the couple that was in front of us.
Couple guys getting ready to decorate the store-front for Christmas.
