Climbing the huge dome designed by Filippo Brunelleschi (the largest masonry dome ever built), is one of the most physically challenging activities to do in the center of Florence, not something for the faint hearted, nor the recently knee-operated!
The question that everyone has on their mind, while facing the climb, is "how many steps are there in Florence's Duomo?". Depending on the sources, the number varies from 414 to 463, the only solution is to count, climb and count, climb and count!
Anyway, the effort is definitely worth it and a fun experience for everyone: kids will love the adventure, adults will love the view.
The dedicated entrance for the Cupola experience is located in the north side of the Duomo. Reservation is mandatory (some combo tickets are also available).
